*2.0 Microcode Change History*
*Release date* *Change Description*
8/2002 Code level SB0A,
Reliability enhancement to improve the idle time sweep algorithm and
optimize track following.
Enhancement were also made to the drive's Predictive Failure Analysis
(PFA) algorithm where the the warning from the drive will be tripped
earlier than before when it see hard read and write errors.
9/2001 Code Level S9RA,
1- Reset Monitor Process: Reset handling were developed to further
reduce the potential of a drive hanging the SCSI bus.A new timer process
that monitors SCSI reset was added.
2- Apply same write ERP(Error Recovery Procedure) steps for reserved
area as user data area.
5/2001 Code evel S9HA:
1- In microcode level S96F, Drive idle time functions--which include
surface safe sweep functions--are only invoked after 10 continues
minutes of drive idle time. System functions in certain
configurations/RAID environments can prevent the drives from going into
safe sweep function due too frequent because read ops performed as part
of RAID parity checking, etc happens every 10 to 20-seconds . In
microcode S9HA, drive idle time function as described above is invoked
after accumulating 120 of 5second idle periods, instead of the default
of 10 minutes continuous idle time.
10/2000 Code level S96F: Fixes and enhancement to improve disk drive
reliability and logic changes to prevent conditions that may result in a
possible
error that could overwrite sectors of data.
8/2000 Code level S93H-Original Release

files in case you need to restore your system.
/Caution:/ The microcode download process is nondestructive to the hard
disks; however, as a precaution, ensure that a backup operation has been
performed on the affected systems PRIOR to the microcode installation.
/Can microcode be installed Concurrently?/
NO. If the disk is part of rootvg or used as a paging device, microcode
download can ONLY be performed while node is "Network Booted" into
"Diagnostic Standalone Mode".
/Is system reboot needed to activate the microcode: /Yes
/Installation Time: /Installation time will vary depending upon the
system configuration
/Procedure for SP System (Nodes):/
Note: Make sure that node on which work is to be performed has been
"fenced" from the switch.
1. Obtain proper microcode diskette from from your IBM Service
Representative.
2. Copy microcode file from diskette onto CWS:
restore -xvq
(file will be copied into the "etc/microcode" directory)
3. Move microcode file from "etc/microcode" directory to the appropriate
Spot(s) that are used by the customer for the node(s) to be updated.
ie:
/spdata/sys1/install/aix4??/spot/spot_aix4??/usr/lib/microcode
(??= level of AIX on your system)
4. To set the Node(s) to boot from network, from CWS, run command:
spbootins -r diag [frame#] [node#] [node count]
(example - - spbootins -r diag 1 13 1)
5. From Perspectives, perform a "Shutdown" for the node(s) to be updated.
