restore of Sysback is missing TCPip info and Nonroot VGs
Desc: AIX 3.2.5
John restored a Sysback tape which contained only rootvg.
Now, his ttys, printers, and non root volume group data are
missing. TCP/IP applications like NIS and NFS are failing
Act: 'lspv' lists hdisk0,1,2,3,4,5,6,8,9,10 as part of vg1 and
hdisk7 as rootvg. This is correct, but none of the
file systems in vg1 list any data. We tried to export
and reimport vg1, but when mounting the filesystems, there
was no data in any of the filesystems except for a couple
'lqueryvg -Atp' on hdisk0 etc lists lv names, but the lvs
seem empty. John remembers after restoring the sysback tape,
a message was displayed stating that 'Non-root Volume Groups'
must now be restored.'
I finally figured out what happened. John booted from the
Sysback tape and chose to restore from it; at that point,
he was presented with a Menu:
1 Input Installation Device rmt0
2 Destination Disks scsi address for hdisk7
3 Startup Disk " " " "
4 Page Space
5 Filesystem Sizing Options
6 Import/Create USER VGs Create
The last option defaulted to CREATE and was not changed
to 'ignore or import' which caused all the information
on VG1 to be lost. The CREATE option should only be used
when the backup tape contains non-root volume groups
as well. Instead of 'importing' vg1 after restoring the
root volume group, vg1 was created effectively losing all
the pointers to the data on the vg1 disks.
The TCP/IP applications are failing because the interface
information is lost as well. The Cu* files do not contain
any information about Network adapters, ttys, or printers.
Next: John will try to restore the /etc/objrepos/Cu* files from
the Sysback tape and then work on restoring vg1 from other
Customer having problems getting token ring defined after
restoring from sysback backup (18.104.22.168). After the initial
restore none of the ttys/printers were defined (using 128 port
controller). The ttys/printers can back have restoring the
/etc/objrepos/CU* files. Still having problems with network.
checked /tmp and found reconfig1. This file is built by
the system when rebooting after restoring from sysback/mksysb.
Edited the file and removed all entries not related to the
token ring (ttys/printers) and then executed it. This still
failed to bring up the network. Ran cfgmgr and received a
method error relating to the token ring card.
checked and the tok0 (token ring card) was not listed by lsdev.
Decided to reboot and this should rebuild the ODM.
After system was rebooted, the token ring card now shows as
available and the network came up as well.
