Symptom Reason Solution
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 are using Microsoft Windows you can
use the StorView “Rescan” feature to relo-
cate the storage solution(s).
StorView displays a
message: “No storage
solution found.”
The host operating
system is not able to see
the storage solution.
Ensure that the Fibre devices appear in your
HBA’s BIOS.
Ensure that you have the latest driver
installed for your HBA.
Probe the SCSI enclosure to ensure that you
see the solution.
Reboot the host and the storage system.
I received the following
message: “Lost commu
-
nication with server. The
server may be down.”
During heavy host opera-
tions and/or data I/O, the
system may become too
busy to complete CGI
requests from the GUI in
the time allocated.
After several updated attempts have failed
you will see this message. At this time you
can try to use the Browsers’ refresh func
-
tion to reload the StorView GUI. If that is
unsuccessful, you may need to stop and then
restart the StorView Server service. If you
continue to receive that message, close the
browser and wait until I/O traffic has settle
down before opening the StorView GUI back
up. You will still continue to receive email
notifications and Event logging.
During heavy data
I/O, when I try to make a
configuration change I get
a failure saying that the
controller is busy
The controller’s onboard
resources are consumed.
Configuration changes during heavy I/ O are
not recommended. You can either wait until
there is less data traffic or keep re-trying the
command until it is successful.
Enclosure Main screen
image is dimmed or
greyed out.
Enclosure Support option
has been disabled.
Access the Controller Information window by
clicking the Controller icon. Verify the option
“Enclosure Support” is checked and click
Apply. Close the window.
