The NVSRAM in this folder is for the DS4300 storage subsystem configurations 
that have up to eight EXP100 (SATA) drive expansion enclosures only attached 
or up to seven EXP810 drive expansion enclosures with SATA disk drive modules 
(E- DDMs) ONLY attached. This NVSRAM file will disable the internal Fibre 
Channel drives slots in the DS4300 storage subsystem chassis. This is not the 
NVSRAM file for the DS4300 storage subsystems with the EXP700, EXP710 or 
EXP810 enclosure attached. This is also not the correct NVSRAM file for the 
DS4300 storage subsystems with the FC/SATA intermix premium feature, which 
will enable the intermix support of either the EXP700/EXP710 or the 
EXP710/EXP810 and the EXP100 drive expansion enclosures behind a DS4300 
storage subsystem. Please refer to the other sub-directory -
For_attachment_of_FC_enclosures_Or_FC-SATA_intermix_only -  for the correct 
NVSRAM file for the DS4300 storage subsystems with FC/SATA intermix premium 
feature enabled or for the DS4300 storage subsystems having expansion 
enclosures with Fibre Channel drives attached.

ATTENTION: DO NOT LOAD THIS NVSRAM FILE INTO ANY OF THE DS4300 STORAGE SUBSYSTEM 
THAT HAVE DRIVES IN THE DS4300 CHASSIS DRIVE SLOTS. THIS WILL CAUSE THE DS4300 
STORAGE SUBSYSTEM NOT RECOGNIZING ANY OF THE DRIVES IN THE DS4300 CHASSIS. THIS 
COULD RESULT IN THE DEGRADATION OF THE DEFINED RAID ARRAY OR A LOSS OF ACCESS 
TO DATA. IF THIS NVSRAM FILE IS LOADED INTO A DS4300 STORAGE SUBSYSTEM WITHOUT 
ANY DRIVE EXPANSION ENCLOSURES ATTACHED, IT WILL PREVENT THE STORAGE SUBSYSTEM 
FROM COMPLETING THE BOOT PROCESS THAT IS INITIATED TO ACTIVATE THE NEW NVSRAM 
SETTINGS, WHICH MIGHT RESULT IN LOST OF MANAGEMENT ACCESS TO the DS4300 STORAGE 
SUBSYSTEM. THERE IS NO SAFETY MECHANISM TO PREVENT THE UNINTENTIONAL LOADING OF 
THIS NVSRAM FILE. 


Please contact IBM support for more information, if required.


Note: The FC/SATA drive type intermixing behind a DS4000 storage subsystem 
requires the purchase of the FC/SATA intermix premium feature entitlement. 
Please contact your IBM resellers or representatives for more information.
