SUMMARY: LSM - Cannot reattach plex, subdisk mode is RELOCATE (RLOC)

All,

Not many responders, many thanks to Roberto Mackun and John Lanier for
their input.


RESOLUTION
==========

On the advice of our vendor, we waited for scheduled reboot.  After reboot,
the disks were no longer in relocate state.  Re-established the mirrorset
OK and re-syncing data currently in progress.

Best regards,

Shaun



Original question
=================

We had a power failure which affected one half of an LSM mirror.  Now the
power is OK we cannot reattach the DETACHED plexes.

Command I am using to reattach;
# volplex -g rootdg att vol-dsk3h vol-dsk3h-01
lsm:volplex: ERROR: Volume vol-dsk3h, plex vol-dsk3h-01, block 0: Plex
write:
        Error: Write failure
lsm:volplex: ERROR: sd dsk3h-01 in plex vol-dsk3h-01 failed during attach
lsm:volplex: ERROR: I/O error on plex vol-dsk3h-01, not attached to volume
vol-d
sk3h


How can we get these plexes reattached ?  What does subdisk mode of
RELOCATE (RLOC) mean?

All pointers appreciated.

I would check the binary.errlog for any traces of a HDD failure or
errors. I suspect write failures and I/O errors are indicative of a HDD
problem.

John Lanier;

May want to try:

#volmend fix clean plex_name

..on all the plexes that are detached/stale.
