121 NO VOLUMES
DETECTED
Informational No configured volumes
were detected at power up.
If there are supposed to be
configured volumes, power
off the MSA1000 and then
all attached storage
enclosures. Unplug and
reinsert all SCSI drives
insuring they are fully
seated in their bays. Check
the cables connecting the
MSA1000 to any attached
storage enclosures. Power
on the attached storage
enclosures and then the
MSA1000.
122 NEW
VOLUME(S)
DETECTED
Informational Configured volumes from
another array controller
were migrated to this array
controller. The
configuration information
has been updated.
123 TOO MANY
VOLUMES DETECTED
Error The array controller only
supports a maximum of 32
configured volumes. More
volumes then that were
detected at power up. This
typically occurs when
migrating a set of volumes
from one array controller to
a different array controller
that already has configured
volumes on it. The migrated
volumes have not been
added.
Remove the migrated drives
and run the Array
Configuration Utility
(ACU). Delete any
unneeded volumes until the
number of existing volumes
plus the number of
migrated volumes is 32 or
less. Add the migrated
drives back.
