( continued )
Inadvertently pulled the
incorrect drive from the
enclosure and the
array is dead.
( continued )
Possible incorrect drive identification
and removal.
For RAID 0 arrays , if you inadvertently
remove a known good drive, the array
will become dead. Once you re-insert
the incorrectly removed drive the
array will return to its working state.
For RAID 1/10 arrays , if you
inadvertently remove a known good
drive, the array will become failed.
Once you re-insert the incorrectly
removed drive the array will return to
its previous state. If the array was
critical, you can then replaced the
known failed drive with a working drive
and assign it as a hot spare and the
array will begin rebuilding.
NOTE: For all arrays removing a drive
as described above will cause all
current processing I/O from the
controller to stop. Any I/O in progress
may have been lost or cause a corrupt
file. Be sure to verify all data stored
during this type of incidence to ensure
data reliability.
Expanding Array is
displayed as “Critical.” Known issue and should be corrected
in the next software release. During an array expansion, the array
remains in a fault tolerant state.
Should a drive failure occur during the
expansion the operation will continue
until it has completed, then if a hot
spare was assigned, a rebuild
operation will begin automatically. If a
hot spare is not assigned, replacing
the failed drive with a known good
drive after the expansion will cause a
rebuild to start, assuming you have
the Auto Hot Spare option selected in
the Controller Parameters.
During the rebuild operation the array
will be critical.
The controller’s IDs
and/or Configuration
WWN was changed
and now there is a
communication failure. When you changed the controller IDs,
a new nexus is established which
requires the operating system and
software to establish new
communication paths. If you using Microsoft Windows you
can use the StorView “Rescan”
feature to relocate the storage
solution(s).
