After a migration from AIX Version 3.2.5 to 4.1.4, the SSA disks are defined. This can be caused by conflicting 3.2.5 and 4.1.4 code for SSA on the system.
The solution is to remove the device and the software and then reinstall the 4.1.4 version of the software. In performing these steps you might encounter the following issues.
If there are any SSA devices defined on the system, remove them. To check for the defined devices, execute:
lsdev -C |grep ssa
To remove the devices, execute:
rmdev -l ssaX -d
The following filesets also need to be removed:
devices.mca.8f97.com devices.mca.8f97.diag devices.mca.8f97.rte
To remove devices.mca.8f97.com and devices.mca.8f97.diag, execute:
cat /CD/usr/sys/inst.images/devices.ssa.disk | restore -xvqf-
Attempting to remove the fileset devices.ssa.disk.rte may fail, giving an error in the predefined database for device ssa0. Proceeding with the removal requires some ODM cleanup. Execute the following sequence of commands only if you are fully knowledgeable about this process.
odmget CuAt | grep ssa0 odmdelete -q name=ssa0 -o CuAt odmdelete -q name=ssa0 -o CuDv odmget CuDep | grep ssa0 odmdelete -q value3=ssa0 -o CuDep odmget CuDvDr | grep ssa0 odmget CuVPD | grep ssa0 lsdev -Cc adapter -- ssa0 is gone
An initial attempt to remove the filesets devices.mca.8f97.com, devices.mca.8f97.diag, and devices.mca.8f97.rte produced the following error:
0301-154: bosboot missing protofile /usr/lib/drivers/ssapin
The next effort was to remove devices.mca.8f97.* with the following command sequence:
mkdir /cd mount -o ro -v cdrfs /dev/cd0 /cd restore -xvqf /cd/usr/sys/inst.images devices.mca.8f97
The following error occurred:
0511-156 cannot find device information
The next command executed was:
cat /CD/usr/sys/inst.images/devices.mca.8f97 | restore -xvqf-
Then there was another attempt to remove the devices, and the following error occurred:
0301-154: bosboot missing protofile /usr/lib/drivers/ssadiskpin
The next effort was to remove devices.mca.8f97.* again with the following command sequence:
mkdir /cd mount -o ro -v cdrfs /dev/cd0 /cd restore -xvqf /cd/usr/sys/inst.images devices.ssa.disk.rte
The following error occurred:
0511-156 cannot find device information
Next this command was executed:
cat /CD/usr/sys/inst.images/devices.ssa.disk | restore -xvqf-
The filesets devices.mca.8f97.com and devices.mca.8f97.diag were successfully removed.
