All,
By request, here is the procedure that I followed to recreate the hardware
database files.
1. View the current disk layout (print this out for later reference).
# hwmgr -view dev
2. If the system disk is under LSM control then detach one half of the root
mirror
# volplex det rootvol-02
3. Drop the system to single user mode
# init s
4. Move the hardware database files and devices to a backup area
# mkdir /backup
# cd /backup
# mkdir etc disk rdisk tape ntape cport member
# mv /etc/dec* /etc/dccd* /etc/dcdd* /etc/dfsc* /backup/etc
# cd /cluster/members/member
# mv .Booted etc/cfginfo etc/dfsl* /backup/member
# mv /dev/disk/* /backup/disk
# mv /dev/rdisk/* /backup/rdisk
# mv /dev/tape/* /backup/tape
# mv /dev/ntape/* /backup/ntape
# mv /dev/cport/* /backup/cport
5. Halt the system and boot to single user mode
# halt
>>> boot -fl s
6. In single user mount to root file system and compare the new device
database with the old one
# mountroot
# hwmgr -view dev
7. Use dsfmgr to rename any devices that have changed
# dsfmgr -m dskX dskY
8. Halt and reboot to multiuser (this will automatically reattach the
rootvol-02 plex)
# halt
>>> boot
Regards
Steve
