Upgrading a Mirrored Volume Online
If this is an internal disk, it powers on and immediately begins to revive if you have
enabled AUTOSTART (page 6-12) and AUTOREVIVE (page 6-13) for both the
specific disk and for the subsystem.
6. If you do not have AUTOSTART and AUTOREVIVE enabled, start the volume and
revive the mirror disk:
-> START $DATA01
When the revive operation is complete on the mirror disk, the primary disk (with the
lower capacity) automatically enters the STOPPED state, substate HARDDOWN.
7. If the new disk has the same capacity but is faster, the primary disk does not
automatically stop when the revive operation is complete. Stop the slower disk and
put it into the STOPPED state, substate HARDDOWN:
-> STOP ($DATA-P, $DATA-B)
8. Physically remove the stopped primary disk.
9. Install the second higher-capacity or faster disk in the location where you removed
the disk.
10. If necessary, put the disk into the STOPPED state, substate DOWN:
-> RESET $DATA01
11. Bring up the volume:
-> START $DATA01
When the revive operation finishes on the primary disk, the entire mirrored volume is
available for use.
