ssa boot hung on led554 after sysback install
Environment: R40 4.1.4
Description: Customer made a backup of the r40 system. Shutdown,
removed the scsi disk, added the ssa disk, rebooted from the sysback
tape, selected the ssa to install rootvg, then installed the system.
Customer stated that all the data restored but on the reboot the
system hung on led554.
Action: Sent customer led554.41.krn fax. Customer went through
all of the fax steps but still hung at led 554.
I determined that the installation occured this way.
1. The boot image was made on a system that currently has ssa up
2. The install image was made on the system where the new ssa
drives are to be attached.
3. The r40 was booted with the ssa boot image.
4. The ssa disk was selected as the rootvg pv and installed with
the install image. This install image was created on a different
system then where the boot image was created.
Thus the boot image used had built in ssa support allowing for a
full service mode boot to occur. But the rootvg that was placed
on the ssa disk did not have ssa device support. So on the reboot
using data from the rootvg disk hung on led 554 due to lack of
ssa device support.
Had customer confirm that all of the following filesets are installed
onto the system where the install image is to be created.
devices.ssa.disk.rte 184.108.40.206 SSA disk drive device drivers
devices.mca.8f79.rte 220.127.116.11 SSA adapter/router device drivers
devices.mca.8f79.diag 18.104.22.168 SSA adapter diagnostics support
devices.mca.8f79.com 22.214.171.124 Common SSA adapter support
ssadiskmc.mc 126.96.36.199 SSA disk drive microcode level 6561
Customer then remade his sysback backup, readded the ssa drive,
restored rootvg onto the ssa disk and rebooted.
This time the system booted with no problem.
