Booting up the new disk, the kernel boots up and everything seems to
go swimmingly, until it tires to mount /var and /usr.
It cannot find the souce domains for those directories which is:
usr_domain#usr -> /usr
usr_domain#var -> /var
I tried doing a mkfdmn /dev/rdisk/dsk6g usr_domain#usr in another
tru64 machine, but it said that it couldn't proceed because
usr_domain#usr already exists in the current tru64 machine (which it
did).
My question is how do I get around this or how do I force the creation
of those label/domains so that the partitions can be mounted ?
Thank you ! Any help is really really helpful, I'm not sure what to do
and I need to get the disk up.
There are symlinks in /etc/fdmns/usr_domain/* which point to the
disks associated with a domain.
Most likely when you inserted the new disks, they go new unique
device names.
There is a utility in /sbin/advfs/advscan, which can rebuild your
/etc/fdmns/* information.
Or you can just play with the /etc/fdmns/usr_domain/* symlinks
yourself. It is not rocket science, however, your mileage may
vary, object are closer than they appear in the side view mirror,
etc...
And if I were a disk device driver developer, instead of an
laid-off AdvFS developer, I might have suggested a command that
renames the devices to be what you want. But I'm not so I only
remember (just barely) the AdvFS commands :-)

Better way is change new dskNUMBER to dksOLDNUMBER - link name |
dsfmgr -e dskNEW (just inserted) dskOLD
dksOLD(this is located in /etc/fdmns/usr_domain)
before you must look which is the new
hwmgr -scan scsi
hwmgr -view dev
(last is the new one)
