Hi-Track Enterprise RAID Agent
Release Notes Hitachi Data Systems

This document describes enhancements and bug fixes to Hi-Track through version C.E.

C.E Mar 15, 2017

Bug Fixes

- [237] Some dump polling failures that occur after dump polling successes go unlogged. Version C.E fixes this.
- [238] MiscFront.dat would always identify the first storage system as the site manager in the case that the site manager is a customer-supplied platform. Version C.E fixes this error.
- [239] An error occurred when an administrator on the dump web interface tried to delete itself. Version C.E no longer allows for an administrator to do this.
- [240] Rebooting the SVP during a dump request would result in a dump requested soon thereafter failing. Version C.E fixes this error.
- [241] Performance data generation would sometime stop if the data files were corrupted. Version C.E fixes this bug.
- [242] FFI parts files older than 72 hours were not actually deleted. Version C.E fixes this bug.
- [243] Systems with serial numbers starting with one or more zeros (including after the 4 or 2 prefix on VSP Gx00/Fx00 or HUS VM systems) are properly supported.
- [244] Systems with Windows 10 installed are now properly identified as such in Hi-Track data.
- [245] Systems that cannot support dump requests are no longer included in dump polling to HDS. This would include those with a SVP Agent version below C.7, or USP or NSC systems.
- [246] The Help button in the Service Manager did not work. Version C.E fixes this bug.
- [247] The log viewer window would sometimes stop responding. Version C.E fixes this bug.
- [248] A rare issue would sometimes occur where a daily transport and a SIM would conflict. Version C.E fixes this bug.
- [249] The batch dump report API function would fail if a FFI dump had ever been generated on the system. Version C.E fixes this bug.
- [250] After changing the dump polling proxy settings to or from SOCKS, or after receiving a dump request under SOCKS, the service manager would poll twice under both SOCKS and non-SOCKS proxy settings. Version C.E fixes this bug.
- [251] Centralized dump requests submitted with any blank fields would fail if the service manager used a SOCKS proxy. Version C.E fixes this bug.

Changes

- [252] Compression pool and virtual volume data is transported on VSP Gx00/Fx00 and G1x00/F1500 systems if the microcode installed is capable of generating this data.
- [253] The installed version of Microsoft IIS Express has been upgraded from 7.5 to 8.0. Customers who have IIS Express 10.0 installed will also be able to use it with the SVP Agent.
- [254] The self-signed SSL certificate for the web dump interface has been upgraded to support SHA-256.
- [255] A new listing of all the dump files that have been transferred to HDS has been added. It can be accessed by clicking "View Transported Dump Files" on the AutoDumps tab.
- [256] A new option to send an email whenever a dump request is received has been added under the Notifications tab.
- [257] A new option to send emails as plain text only has been added to the Notifications tab.
- [258] A new option to disable transport of Hi-Track data in the regular "call-home" process has been added. It is highly recommended that this data be allowed to transfer to HDS (and that this option is not used) for improved customer support.
- [259] The default dump polling interval has been changed from every 120 seconds to every 180 seconds. Any value below 180 seconds will be ignored, and the site manager will poll every 180 seconds in this scenario.
- [260] The serial number of the affected system is now included in a SIM notification email.
- [261] SIMs generated during a daily or weekly transport will now be transported immediately to HDS rather than at the end of the transport.
- [262] A storage system that can no longer initiate communication with the site manager will no longer transport Hi-Track environment data to HDS. A healthcheck case will be opened on Siebel so that the connection issue can be investigated.
- [263] The integrated nsoftware IPWorks! SSL components have been upgraded from version 8.0 to 9.0.
- [264] The "Trigger Dump For All Subsystems" button was removed from the Service Manager GUI.
- [265] Logging for AutoDump requests and polling has been improved.

- [227] Hi-Track checks the VSP Gx00 identifying registry key on every BackSvc start-up instead of checking only once at install.

C.B May 07, 2015

Bug Fixes

- [213] The Hi-Track Site Manager does not properly carry over the proxy type configuration when upgraded to C.A.. As a result, Hi-Track does not correctly recognize the proxy configuration or changes made to it. Version C.B fixes this.

C.A April 22, 2015

C.9 March 23, 2015

Bug Fixes

- [199] AutoDump Polling Configuration Window Hangs on Close: The AutoDump Polling Configuration sub-window of the Hi-Track Service Manager may hang for a noticeable amount of time if the Apply or Close buttons are pressed immediately after the Test button has been pressed. Version C.9 fixes this.
- [200] Selected checkboxes reset after a few seconds on the AutoDump Web Interface's Home page. Version C.9 fixes this.
- [201] The OK button doesn't appear after adding or editing a Subsystem's IPv4 or IPv6 Registration Address. Version C.9 fixes this.
- [202] A changed IPv4 or IPv6 Registration Address requires a manual restart of the SVP Agent service in order to update the Site Manager with the changed address if the SVP Agent service is running when the change is made and already registered and connected to the Site Manager. Version C.9 fixes this.
- [203] FrontSvc.ConnectToBack error messages spam the Site Manager logs upon continued failure. Version C.9 fixes this.
- [204] FrontSvc.ConnectToBack exceptions hang dump and file transfers. Version C.9 fixes this.
- [205] The Resend SIMs option resends SIMs every other day rather than every day. Version C.9 fixes this defect.

Changes

- [206] Adds support for HUS VMs configured with a Dense-60 drive boxes.
- [207] Added a Validate SSL Certificate option for polling any configured servers for dump polling. This option is disabled by default and can be found in the Hi-Track Service Manager's AutoDump Polling Configuration sub-window.
- [208] Added an Interface Configuration dialog under the Hi-Track Service Manager's AutoDumps tab from which the admin password for the AutoDump Web Interface can be reset to the default value.
- [209] Collects Protection Level Information on VSPs.

C.8 Nov 24, 2014

Bug Fixes

- [183] SIM report failure: Hi-Track can fail to report SIMs under these specific conditions. 1) Both dialup and IP transport methods are configured. 2) The IP transport methods configured do not work. 3) The dialup method is listed at 1st (that is at the top of) in the contact methods list. Version C.8 fixes this.
- [184] VSP G1000 SVP Agent unexpected failure: The Hi-Track SVP Agent can unexpectedly shutdown and require restart on VSP G1000 systems on which 4 or more DKC batteries are configured. Version C.8 fixes this defect.
- [185] VSP G1000 BatteryLifeEach.Dat files are incomplete: The BatteryLifeEach.dat generated by Hi-Track SVP Agent on VSP G1000 systems is incomplete. Version C.8 fixes this.
- [186] SVP Agent fails to read microcode levels upon start-up. Version C.8 fixes this.
- [187] Unread microcode level restricts DAT File Generation for DAT files whose API is microcode level dependent. Version C.8 fixes this.
- [188] FTPS contact methods fail if the Transfer to HDS Only option is configured for it. Version C.8 fixes this.
- [189] Site Managers may register an incorrect IP address for SVP Agents on a different network if the IP address of the Site Manager starts with a different octet than the SVP Agent. This is not guaranteed to happen but may occur depending on the ordering of the SVP Agent's assigned IP addresses. Version C.8 fixes this.
- [190] The SVP Agent service runs when it shouldn't on non-subsystem machines. The service starts upon restart and cannot be stopped via the Service Manager because the UI control is not enabled. Version C.8 fixes this.
- [214] SIM triggered AutoDumps don't label the generated AutoDump with the triggering SIM code. Version C.8 fixes this.

Changes

- [191] VSP G1000 does not generate BatteryLife.dat due to dropped support.
- [192] SVP Agents may explicitly specify the IP address used to register with a Site Manager if the SVP Agent is not also a Site Manager.
- [193] Added IPv6 address support. Site Managers can be registered with IPv6 from an SVP Agent exactly as an IPv4 address would be registered. SVP Agents can define IPv6 addresses to use for registration from the Subsystems tab of the Hi-Track Service Manager if the SVP Agent is not also functioning as a Site Manager.
- [194] SIM triggered AutoDumps are now appended with _auto_SIMREF where SIMREF is the SIM reference that triggered the dump.
- [195] Added support for appending SR numbers to polling triggered AutoDumps.
- [196] Enhanced dump polling to better detail what stage of the dump process the Site Manager is on.
- [197] The Dump Interface now supports batched request.
- [198] Hi-Track is now FIPSs compliant and will run as intended on Windows operating systems with that FIPS compliance enabled.

C.7 April 21, 2014

Bug Fixes

- [172] IOException hangs Hi-Track transfer: An IOException during a transfer would cause the transfer process to hang until the Site Manager was restarted. Version C.7 fixes this.
- [173] SIM transport fails with incorrect contact method: The Site Manager may fail to transport a SIM on subsequent transfer attempts if the previous attempt failed due to an incorrectly setup contact method. Version C.7 fixes this.
- [174] HUS VM unable to determine the system type after install: The API used to generate BatteryLife.dat is not supported on the HUS VM systems. Version C.7 eliminates BatteryLife.dat generation for HUS VM systems.
- [175] The AutoDump Web Interface on Windows Server 2012 R2 or Windows 8.1: The AutoDump Web Interface component does not display on either Windows Server 2012 R2 or Windows 8.1. Version C.7 fixes this.
- [176] The AutoDump Web Interface error page: The error page for the AutoDump Web Interface does not display normally. Version C.7 fixes this.
- [182] VSP G1000 DAT generation halts on LuPath.dat: The SVP Agent hangs may hang on generation of LuPath.dat. Version C.7 fixes this.

Changes

- [177] VSPG1000 Support Added: VSPG1000 systems are officially supported in version C.7.
- [178] Collecting BatteryLifeEach Information: On HUS VM systems, Hi-Track uses an API to collect the life information of each battery.
- [179] Adding an SR to AutoDumps generated from the Web Interface: Users may now attach an SR number to an AutoDump request submitted by the AutoDump Web Interface.
- [180] Concurrent SIM transfer and AutoDump generation: AutoDump generation submitted by either the GUI or AutoDump Web Interface no longer blocks SIM transfer until the dump is generated.
- [181] The MakeHiTrackDb utility defaults: The MakeHiTrackDb utility now points towards default installation locations.

C.6 January 22, 2014

Bug Fixes

- [159] HUS VM SIM data corrupt: SIM messages transferred to Hi-Track from an HUS VM system with a serial number with leading zeros (after the leading "2" — i.e. "201234") were unreadable by the Hi-Track server. Version C.6 fixes this.
- [160] HUS VM unable to determine the system type after install: The SVP Agent for an HUS VM system is unable to determine the system type upon a fresh install. Version C.6 fixes this.
- [161] HiTrackLogs.zip fails to close: An open log file fails to zip during a transfer, causing the transfer to fail. Version C.6 fixes this.
- [162] SIMs Report When They Should Not: SIMs reported to the Hi-Track Center regardless of the front's "Report SIMs" setting. Version C.6 fixes this.
- [163] HUS VM SIM Emails Not Sent: SIMs reported to the Hi-Track Center were not emailed to their designated recipients. Version C.6 fixes this.
- [164] HUS VM Serial Truncation: The serial numbers of HUS VMs dropped the leading '2' after certain UI interactions. Version C.6 fixes this.
- [165] Duplicated localhost Subsystem Upon Install: The localhost subsystem entry is added twice to subsystems upon initial install. Occurs very rarely. Version C.6 fixes this.

Changes

- [166] Collecting DKU Type Information: On HUS VM systems, Hi-Track uses a new API to collect the life information of each battery.
- [167] Trigger AutoDumps from the Service Manager: AutoDumps can be generated and transferred to the Hi-Track Center from the Service Manager by either targeting a specific subsystem or all subsystems monitored by a Site Manager. This feature is supported on USP V/VM, VSP, and HUS VM.
- [168] Trigger AutoDumps from a Web Interface: AutoDumps can be generated and transferred to the Hi-Track Center from a web interface if this feature is enabled on the Site Manager's Service Manager. This feature is supported on USP V/VM, VSP, and HUS VM.
- [169] Trigger AutoDumps by SIM reference code: If enabled in the Service Manager, AutoDumps can be automatically generated and transferred to the Hi-Track Center if a reported SIM reference code matches one that's listed in the SIM AutoDump parameter file. This feature is supported on USP V/VM, VSP, and HUS VM.
- [170] Includes Pre-populated HTTPS, FTPS, and FTP Contact Methods in the "Add Contact" dialog for the Hi-Track Service Manager.
- [171] Changed Contact Method Passes to rotate through defined contact methods rather than try each method a specific number of times before moving on to another. Preference is given to IP transport methods and if these all fail within a timeout period then Dial-up transport methods are attempted. In addition, the default retries configuration parameters only apply to the dial-up transport methods. The IP transport methods are looped through where applicable until a transport timeout period elapses.

C.5 October 29, 2012

Bug Fixes

- [157] VSP systems failing daily transfers: Under some circumstances Hi-Track Agent version C.4 on VSP systems running some versions of V-04 microcode would crash during file generation and fail to transfer data files to the Hi-Track Center. Version C.5 fixes this problem.

- [158] Hi-Track Service Manager application prevents log off: Hi-Track Agent version C.4 installed on systems other than SVPs prevented the user from logging off of a console session unless the Service Manager application was closed. Version C.5 fixes this problem.

C.4 September 18, 2012

Bug Fixes

- [149] Dial-up incidental calls send wrong micro-code version for back systems: Under some circumstances a dial-up incidental call would report an incorrect microcode version for remote systems reporting a SIM. Hi-Track C.4 fixes this issue.

Changes

- [150] Support for HUS VM systems: Hi-Track was updated in C.4 to support HUS VM storage systems.
- [151] Collecting Storage System Data in XML format: on HUS VM systems or VSP systems with micro-code version 7004000000 and above, Hi-Track calls the appropriate API functions to collect storage configuration data such as package information as well as SSB and SIM data. Moreover, Hi-Track transports these new XML data files during the daily and weekly data transports.
- [152] Collecting Pool Information Ex2: On HUS VM systems or VSP systems with micro-code version 7004000000 and above, Hi-Track uses a new API to collect the ‘ex2’ version of the HDP pool data.
- [153] Collecting License Information Ex: On HUS VM systems or VSP systems with micro-code version 7004000000 and above, Hi-Track uses a new API to collect the ‘ex’ version of License data.
- [154] Collecting Each Battery Life Information: On HUS VM systems or VSP systems with micro-code version 7002500000 and above, Hi-Track uses a new API to collect the life information of each battery.
- [155] Additional information included in SIM notification emails: Additional information including error location and HDD serial number (when applicable) is now included in notification email messages if the system is configured for email notification.
- [156] Changed the Service Manager application to support minimize, restore, display in taskbar, and to not enforce an "always on top" window state.

C.3 May 1, 2012

Bug Fixes

- [147] SVP Agent Service (BackSvc.exe) consumes a high percentage of CPU time: In Hi-Track C.2, if the SVP agent service runs continuously for a long period of time, it would eventually uses near 100% of the CPU. As a result, the Hi-Track application may not be able to write to log files or transport data to the center. We have reports indicating that the issue has occurred as early as 30 days after starting the SVP agent service. Hi-Track C.3 fixes this.
- [148] Email Notification for Simultaneous SIMs: If simultaneous SIMs occur on an SVP, previous versions of Hi-Track may not send email notification for all of them. Hi-Track version C.3 was modified to send notification emails for all SIMs, including those that occur simultaneously.

C.2 October 31, 2011

Bug Fixes

- [136] Upgrading Hi-Track: When installing Hi-Track C.1 on a system that is running a previous version of Hi-Track, the C.1 installer incorrectly displays a message indicating that Hi-Track C.1 is already installed and prompts the end-user to either repair or remove Hi-Track. In C2, Removing the previous version of Hi-Track is part of the installation process and does not require user intervention.
- [137] SIMS Email Notification: Prior to version C.2, Hi-Track failed to send SIMS notification emails when deployed on a stand-alone system. Hi-Track C.2 fixes this.
- [138] SMTP authentication: In previous versions of Hi-Track, users could specify the email server username and password in the Notification tab but the Hi-Track application did not forward the authentication credentials to the SMTP mail server. Version C.2 correctly sets the username and password if the SMTP server requires authentication.
- [139] Site Manager Handle Count: if a dialup transport is defined as the only contact method and none of the dialup succeeds, the Hi-Track Site Manager consumes many file handles without releasing them. this is resolved in version C.2.
- [140] Proxy Server Domain Authentication: Hi-Track version C.2 was modified to support domain authentication for proxy servers.

Changes

- [141] Transporting Uncompleted SIMS: Hi-Track sends a list of uncompleted SIMs to the center during data transfer.
- [142] Manual Contact Method: Hi-Track C.2 introduces a new contact method called Manual that stores the collected data in the c:\HDS\FtpStage instead of sending it to the Hi-Track center.
- [143] Configurable SMTP Port: Allows users to specify the SMTP port for email event notification. The default port is 25.
- [144] HTTPS as Default Transport Method: Previous versions of Hi-Track were pre-configured with a dial-up transfer method. This has been changed in C.2 and Hi-Track displays a generic HTTPS connection as the preferred transfer method. As a result, ‘Answer incoming calls’ and ‘Enable RAS dial-back’ checkboxes are in the unchecked state by default.
- [145] Notification by SIM Severity: In version C.2, the Hi-Track application can be configured to send email notification based on the severity of SIMs.
- [146] Validating SSL Certificate: Previous versions of Hi-Track rejected SSL certificates that were signed by untrusted authorities. Therefore, it was not possible to employ the HTTPS method to transfer data to servers with self-signed SSL certificate. In version C.2, Hi-Track can be configured to skip the server certificate validation process and transfer data to any web server via HTTPS.

C.1 July 27, 2010

Bug Fixes

- [124] Collection of LUSE data: Prior to version C.1, Hi-Track did not completely retrieve the data about configured expanded LUSE. Version C.1 calls the appropriate APIs to collect all the LUSE information. It will gather the configured LUSE data on all the large RAID SVP types.
- [125] Log sizes grow unexpectedly: There was one report suggesting that the Hi-Track log file size becomes too large and takes all the C drive space. To prevent this rare incident from happening, Hi-Track was modified to check the log size before writing to it. In version C.1 or later, Hi-Track will overwrite the log file if the file size exceeds 2 megabytes.
- [126] Failing to FTPS to Solaris FTP Server: In rare occasions, Hi-Track reports an error when sending data via FTPS to Solaris FTP servers. Further investigation revealed that the error occurs on logoff event after data transfer is completed. Hi-Track version C.1 resolves this issue.
- [127] Stopping Site Manager Service: If there is no modem attached to the Hi-Track host system, the Site Manager Service cannot be correctly stopped as it is waiting for a reply from an absent modem. Hi-Track C.1 resolves this issue.
- [128] Reporting SSB data: Prior to version C.1, Hi-Track was not able to report all SSB data when the primary transfer protocol was HTTPS or FTP. This issue has been resolved in version C.1 and Hi-Track successfully transfers the SSB information to the center using HTTPS or FTP.
- [#] Standby SVP Agents don't switch to primary: For dual SVPs, when the primary SVP Agent fails, the standby SVP agent does not automatically switch to a primary. Switching requires manually restarting the standby SVP Agent's service. Hi-Track C.1 resolves this issue.

Changes

- [129] Support for VSP systems: VSP is the latest system of the large RAID family of HDS storage products. Hi-Track was updated in C.1 to fully support VSP storage systems.
- [130] Dial-up configuration on VSP: Hi-Track does not support dial-up data transfer or RAS dial-back by default on VSP storage systems as these systems do not have a built-in modem. However, users can optionally install one of the modems that is supported by Hi-Track (please refer to the Hi-Track help document for the list of Hi-Track approved modems). In version C.1, the Hi-Track Service Manager is able to detect whether the host platform is equipped with a modem. It allows dial-up data transfer and RAS dial-back only if finds a modem on the startup event.
- [131] Hi-Track Installation Location: In C.1, the Hi-Track installer will prompt the end-user to select a target installation directory. The default folder is “C:\Program Files\Hitachi Data Systems\Hi-Track\” for USP V/VM, NSC, and USP. For VSP, the default folder is “C:\Program Files (x86)\Hitachi Data Systems\Hi-Track.”
- [132] FTPS to non-HDS Centers: Prior to version C.1, Hi-Track was able to only transfer data securely to HDS centers. This restriction has been modified in version C.1 and Hi-Track can send data to any server using the FTPS transfer protocol. To use FTPS to send data to a non-HDS center, uncheck the box labeled Transfer to HDS only on the FTP Method Properties panel.
- [133] Collecting and Transporting csv.zip: If the appropriate command-line tool is installed on an SVP, Hi-Track will call it to collect the csv.zip data. Similar to dat.zip and config.zip, the csv.zip is stored in c:\hds and sent to the HDS center during data transfer.
- [134] SVP Agent Connectivity Test: In Hi-Track version B.D to C.0, any Vista computer failed the Ping portion of the SVP Agent Connectivity Test facility of the Hi-Track Service Manager. Hi-Track version C.1 was updated to resolve this problem.
- [135] Collection of SVP Antivirus data: Starting with version C.1, Hi-Track uses a different method to retrieve information from any antivirus installed on the host system. The new method works on all SVP types.

C.0 June 4, 2009

Bug Fixes

- [117] FCGS Symbolic data collection caused Hi-Track failures: Item #116 in version B.F was modified to only generate FCGS symbolic data if the USPV/VM subsystem is at or above the V04+1 microcode level. A workaround that was offered for this problem was to uncheck the box in the Service Manager program to disallow collection of FCGS data. If you cleared this checkbox to work around the problem, please replace the check in the checkbox after upgrading to C.0 and test a full transfer (including new file generation) to the Hi-Track Center. Watch both the Site Manager log and Agent log during file generation and transfer to ensure that it completes without errors.
- [118] Testing transfers in the Service Manager: If a user initiated a test Daily transfer in the Service Manager program and the day of the week was the same as the day of the week the system was configured to do weekly transfers, the call type would be changed to Weekly.
- [119] System Busy message: When attempting to initiate a data transfer to the Hi-Track Center while connected through a RAS session, the Hi-Track agent would respond that the system was busy regardless of the configured transport methods. Version C.0 will allow a transfer provided that the primary transport method is not dialup.

Changes

- [120] Collection of HDP data: A new API was added for USPV/VM systems to collect information about configured HDP pools and volume information. This API will be called and the data collected for systems running microcode versions V05 and above. This information is displayed on the Hi-Track web pages for USP V and USP VM systems configured with HDP pools and volumes.
- [121] FTP data transfers changed to PUT: For historical reasons, in the past FTP transfers to the Hi-Track Center have appended files to the Hi-Track FTP servers. With this version FTP transfers have been changed to uploads which will overwrite any existing files. This change will prevent misconfigured agents from causing problems with the Hi-Track FTP servers.
- [122] Installer change: A change was made to the agent bootstrap installer to automatically remove previous versions of the Hi-Track agent before installing a new version. This should result in a higher success rate for upgrade installs.
- [123] Return value from dialup command changed: The return value for a dialup Center command was changed in this version to acknowledge the command sent.
