    Hi Managers,

    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.

    Further information;
