Hello to one and all,
After the routine replacement of an SSA disk in a mirrored data VG on
a machine running AIX
4.3.3, the last step of the procedure called for
remirroring the disks using the "mirrorvg -m" command accompanied by a
specific list of hdisks. This step always takes quite a few hours,
and for extra security we always run it directly from the system
console (tty), to avoid any possible network issues.
This time, however, something went wrong, and it looks as though the
console was disconnected while the mirrorvg process was running.
Nobody had access to the server room, so we're certain that this was a
technical glitch and not the result of human error or intervention.
As a result, the mirrorvg process was orphaned and the volume group is
locked. Using the ps command to identify processes running under
'root', we find the following:
