1.1  Limitations
---------------------

NOTE: For limitations in certain operating system environment, refer to the 
readme file that is included in the DS3000 Storage Manager host software 
package for that operating system environment.

Limitations with versions 07.35.41.02 release.
  
1. DS3300 Linux hardware initiator iSCSI solution is currently only 
   supported when using a version of SANSurfer for iSCSI starting with
   version 5.00.32. 

2. IBM AIX currently only supports the DS3400 storage subsystem.

3. During deletion of a logical drive it is possible that a "ghost" (I.E. a 
   logical drive displayed with a dotted line picture) will be visible.  If 
   this occurs you will need to go to Modify -> Edit Host-to-Logical Drive 
   Mappings.  Then select the logical drive in question and click on the remove 
   option.  This will destroy the "ghost" logical drive.
   
4. Arrays created using RAID levels 3,5, or 6 that will be mapped to an AIX host,
   need to contain at a minimum five (5) hard drives.

5. VMware is currently only supported on the DS3300 using software 
   initiator.

6. There is no Solaris management client for DS3000 storage subsystems.

1.5 Level Recommendation for the update
-----------------------------------------

     1. Storage Controller Firmware versions:
        a. DS3200: FW_DS3200_07354102
	b. DS3300: FW_DS3300_07354102
	c. DS3400: FW_DS3400_07354102
                                                       
     2. Storage Controller NVSRAM versions: 
        a. DS3200 - Single Controller: N1726D32LR335V02.dlp                  
        b. DS3200 - Dual Controller  : N1726D320R335V06.dlp 
        
        c. DS3300 - Single Controller: N1726D33LR335V02.dlp                  
        d. DS3300 - Dual Controller  : N1726D330R335V05.dlp
         
        e. DS3400 - Single Controller: N1726D34LR335V02.dlp                  
        f. DS3400 - Dual Controller  : N1726D340R335V05.dlp 

       
      Note: The DS3000 storage subsystems that are shipped from the factory
            may show the NVSRAM version with a different first character 
            prefix other than the "N" prefixed as stated. As long as 
            the rest of the version information after the first 
            character are the same, both the manufacturing NVSRAM 
            version and the "N" prefixed NVSRAM version are the same. 
            You do not need to update your DS3000 storage subsystem with 
            the  "N" prefixed NVSRAM version as stated above. For 
            example, for a DS34000, the N1726D340R917V15 and 
            M1726D340R917V15 (or C1726D340R917V15 or D1726D340R917V15, 
            etc...) versions are the same because both versions share 
            the same "1726D340R917V15" string. The M1726D340R917V15 (or 
            C1726D340R917V15 or D1726D340R917V15, etc...) version was 
            loaded to the DS3400 storage subsystem at the factory. The 
            N1726D340R917V15 version is the one that was posted to the 
            DS3000 support web site for download.             
                                          
   Refer to the following IBM System Storage™ Disk Storage Systems 
   Technical Support web site for the latest released code levels.

3.0  Helpful Hints 
------------------

1. The IBM System Storage DS3000 Storage Manager version 10 Installation 
   and Support Guide for Microsoft Windows Server, Linux, Novell 
   Netware, and VMWare ESX Server are available on IBM's Support Web Site
   as a down-loadable Portable Document Format (PDF) file.
   
2. The IBM System Storage DS3000 Storage Manager version 10 Installation 
   and Support Guide for AIX and Linux on POWER is available on IBM's 
   Support Web Site as a down-loadable Portable Document Format (PDF) file. 

3. The DS3000 Premium Feature - storage partitioning, plus Copy Services 
   Premium Features - FlashCopy, VolumeCopy and FlashCopy VolumeCopy 
   - are options purchased separately. 
   
4. Enablement of the 07.35.41.02 controller firmware provides support for up 
   to 4 storage partitions for the DS3200, DS3300 and DS3400 . If additional 
   storage partitions are needed, various storage partition feature upgrade 
   options can be purchased to increase the maximum number of supported storage      
   partitions.
   
5. The Storage Manager (SM) host software version 10.35 client script 
   window looks for the files with the file type of  ".script" as the possible
   script command files.
   
6. If the management port is connected to a network infrastructure that will 
   periodically be performing security port scans, please ensure that the 
   switch port that connects to the management port(s) is set to auto-negotiate.  
   In some instances, when a port is set to a dedicated link speed, after a port 
   scan the management port will become unresponsive and will not recover until 
   after the storage subsystem is power cycled. 
   

=======================================================================

4.0 Configuration Information
-----------------------------

        
4.1 Configuration Settings
--------------------------

1. By default the Storage Manager 10.35 software does not 
   automatically map logical drives if storage partitioning feature is
   enabled. This means that the logical drives are not automatically 
   presented to host systems. 
                                          
   Refer to the IBM DS3000 Storage Manager documentation or online help 
   to learn more about creating storage partitions and changing host types.

2. When you are configuring the DS3300 or DS3400 storage subsystems as 
   boot devices, contact IBM support for supported configurations and 
   instructions for configuring LUNs in the IBM storage subsystems as 
   boot devices. 

=======================================================================

4.2 Unsupported configurations
------------------------------

   The configurations that are currently not being supported with controller 
   firmware version 07.35.41.02 in conjunction with DS3000 Storage Manager 
   version 10.35 are listed below:

   1. A configuration in which either a software or hardware iSCSI initiator
      is directly connected to a DS3300 storage subsystem.
      
   2. A configuration in which the host is connected to a iSNS server using 
      only IPv4 and the DS3300 is connected to the iSNS server using only 
      IPv6.
