Problem Fixed:

This new microcode level includes code changes to enhance long-term disk drive reliability.
 

Disk Drives Affected:

This microcode is for the following IBM SCSI hard disk drive:

  Size                         Model                  FRU # or             Assembly
                                                           FRU ASM#              P/N
----------------  -------------------   ---------------        ----------

18.2GB(80 Pin)  DDYS-T18350M      07K7406            07K7404
36.4GB(80 Pin)  DDYS-T36950M      07K7402            07K7400
 
 

Machines Affected:
All RISC/6000 and SP2 machine using these SCSI disk drives.
NOTE: The SP2 procedure requires copying microcode files to the appropriate SPOT(s). Therefore, it is highly  recommended that someone with an appropriate level of AIX experience and expertise performs the update, preferably the System Administrator or person(s) designated as responsible for making software updates to the system.
 

Operating System levels supported:

All levels of AIX that this product was announced on.
