The NVSRAM in this folder is for the DS4300 storage server configurations that 
have up to eight EXP100 (SATA) drive expansion enclosures only attached. This 
NVSRAM file will disable the internal Fibre Channel drives slots in the DS4300 
storage server chassis. This is also not the correct NVSRAM file for the 
DS4300 storage servers with the FC/SATA intermix premium feature, which will 
enable the support of the EXP700/ EXP710 and the EXP100 drive expansion 
enclosures behind a DS4300 storage server. Please refer to the CD that is 
shipped with the FC/SATA intermix entitlement for the correct NVSRAM file for 
the DS4300 storage server with FC/SATA intermix premium feature.


ATTENTION: DO NOT LOAD THIS NVSRAM FILE INTO ANY OF THE DS4300 STORAGE SERVERS 
THAT HAVE DRIVES IN THE DS4300 CHASSIS DRIVE SLOTS. THIS WILL CAUSE THE DS4300 
STORAGE SERVER 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 SERVER WITHOUT 
ANY DRIVE EXPANSION ENCLOSURES ATTACHED, IT WILL PREVENT THE STORAGE SERVER 
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 
SERVER. 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 server 
requires the purchase of the FC/SATA intermix premium feature entitlement. 
Please contact your IBM resellers or representatives for more information.
