Dan,
Yes, The system boots into AIX fine, all the daemons and background services
start normally.
Yes hdisk0 with rootvg is mounted properly with all the partitions hd1-7
Of course I reseated the scsi adapter and verified and re-verified the
cable/hardware connections.
All seem OK, and furthermore the RS/6000 bios detects the scsi adapter and
Hard drives correctly.
(So it is unlikely that it is a cable/connection/hardware problem).
Certaily an ODM corruption is a posibility, since I have used extendvg and
reducevg many times.
Also some other previously connected Hard drives were taken off-line and
stayed as "defined" then
afterwards I reconnected different hard drives but using the same scsi id of
the previously disconnected
hard drives, but were distinguished as a different drive, ie instead of
hdisk2 with scsi id 2, it was
detected as hdisk8 with scsi id 2. Doing all these operations over a period
of time certaily can corrupt ODM.
Anyway, any other ideas about how to rescue this system without digging too
much into ODM commands,
will be greatly appreciated.
