Hello List,
I was unfortunaly picked out to solve a LSM-problem and didn't work with it for about 4 years, so any help here is
desperately needed and apreciated.
My System is a Cluster, version 1.5x, and TRU64 V4.0D.
It looks like I have problem with my asedg disk group.
the failing device seems to be the rz25g in that group.
The Status iss "disabled".
I was personally not onsite yet, but what the user told me about how the problem occured it might well be, that there isn't necessarily a hardwareproblem on that phys. disk in the vol-group.
From what I remember from Volumes, they can be enabled and re-started from that state.
So my 3 questions are:
1.)
If the diskstatus has only to be changed to be enabled und started, what is the procedure to do that?
2.)
If I have to replace the disk and want to put the new disk in the same location, in what sequence and with what voldiskadm commands do I have to do that.
I think I have to remove the defective disk from the volgroup (how?), insert the new disk and initialize it for use with LSM (voldisksetup ..and what?) and integrate the new disk to the asedg diskgroup (how ?)
3.) For a general understanding: In case there would be only one underlaying physical disk on a volume, can this one disk be removed out of the diskgroup for replacement
or how would you replace a disk in that configuration?
Here are the corresponding lines from the log:

Wow, that's it.
