System Crashes During stmsboot
During the reboot following stmsboot enable (-e), disable (-d ), or update (-u) operations, if
your system hangs, panics, or fails to boot, follow the instructions below to recover your
original conguration.
▼
To Recover from a System Crash
Boot the system from another disk, CD, DVD, or over the network.
Run the fsck your-root-device command where your-root-device is your original root device.
# fsck your-root-device
Mount your original root device.
# mount your-root-device /mnt
Restore your original fp.conf le (for FC multipathing) or mpt.conf (for SAS multipathing) as
follows.
■
If you ran the stmsboot -e command or stmsboot -d command:
– For SAS multipathing, type the command cp /mnt/etc/mpxio/mpt.conf
/mnt/kernel/drv/mpt.conf
– For FC multipathing, type the command cp /mnt/etc/mpxio/fp.conf
/mnt/kernel/drv/fp.conf
■
If you ran the stmsboot -u command, and you modied either the fp.conf le or the
mpt.conf undo the changes you made to this le by editing either the
/mnt/kernel/drv/fp.conf or the /mnt/kernel/drv/mpt.conf les.
Undo any other changes you made to the multipathing conguration prior to running the
stmsboot command.
For example, if you modied the scsi_vhci.conf le, undo the changes you made to this le by
editing the /mnt/kernel/drv/scsi_vhci.conf le.
If you modied the device settings of your storage arrays, restore their original settings.
Restore your original /etc/vfstab le:
# cp /mnt/etc/mpxio/vfstab /mnt/etc/vfstab
The /mnt/etc/mpxio/vfstab le is a copy your original /etc/vfstab le that the stmsboot
command saved prior to updating your vfstab le. A /mnt/etc/mpxio/vfstab le will not
exist if the stmsboot command has not modied your vfstab le.
