Hi Farren,
Easiest is to create new DB & LOG volumes on the new disk of the same
amount largeness.
If you have done this with a 'dsmfmt' it is sufficient to create a
"second mirror" with 'dbcopy'.
In the q dbv the third column should be filled.
After is says Sync'd, and you have done the same for the log file (q
logv), you can remove the busted copy (dele dbv & dele logv), leaving
two volumes (one original and one copy) in place.

Subject: [ADSM-L] Recovery of mirrored db and log volumes
Hi TSMers
Running TSM 5.1.6.2 on Solaris.
Two of the internal disks in our sun E250 server are used to house the
database and log volumes and copies (using TSM's internal mirroring).
This
morning one of the disks failed and we are now awaiting a replacement. I
have had a look at the documentation for recovering mirrored volumes and
all I have found is this.
1) Query the database and log volumes
2) Place failed volumes off-line (TSM already did this for me)
3) Fix device
4) Allocate space for new copies with DSMFMT
5) Bring new volumes on-line.
Now, at the moment, the off-line copies are still defined within TSM, so
what I want to know is this. Once I have got the new disk in place and
created the necessary file systems, can I just recreate the required log
and DB volumes using the dsmfmt command and give them the exact same
location,name and size? I am assuming that if this is the case I can
then
just vary the off-line copy back on-line? Is this correct or am I
missing
something?
Many thanks in advance
