5.5 HP StorageWorks X9720 Network Storage System Administrator Guide (AW549-96026, March 2011)

Re-seating an X9700c controller
Make sure you are re-seating the correct controller. You should observe both a flashing amber LED
and the seven-segment display. An H1 or C1 code indicates controller 1 (left) is halted; an H2 or C2
code indicates that controller 2 (right) should be re-seated.
NOTE:
There is no need to disconnect the SAS cables during this procedure.
To re-seat the controller:
1. Squeeze the controller thumb latch and rotate the latch handle down
2. Pull the controller out until it has clearly disengaged—there is no need to fully remove the controller.
3. While the controller is still disengaged, ensure that the SAS cables are fully inserted.
4. Push the controller fully into the chassis so it engages.
The seven-segment display shows different codes as the controller boots. After a few minutes, the
seven-segment display should show a constant value (if you had previously run a firmware flash utility,
this can take up to 25 minutes). If the value is “on,” the controller is operating normally. Otherwise,
see “Identifying the failed component” on page 117 for more information.
Viewing software version numbers
To view version information for a list of hosts, use the following command:
<installdirectory>/bin/ibrix_version -l [-h HOSTLIST]
For each host, the output includes:
• Version number of the installed file system
• Version numbers of the IAD and File System module
• Operating system type and OS kernel version
• Processor architecture
The -S option shows this information for all file serving nodes. The -C option shows the information
for all X9000 clients.
The file system and IAD/FS output fields should show matching version numbers unless you have
installed special releases or patches. If the output fields show mismatched version numbers and you
do not know of any reason for the mismatch, contact HP Support. A mismatch might affect the operation
of your cluster.
