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

9. If the seven-segment display now shows “on,” run the exds_stdiag command and validate
that both controllers are seen by exds_stdiag.
10. If the fault has not cleared at this stage, there could be a double fault (that is, failure of two I/O
modules). Alternatively, one of the SAS cables could be faulty. Contact HP Support to help identify
the fault or faults. Run the exds_escalate command to generate an escalate report for use by
HP Support as follows:
# exds_escalate
11. At this stage, an X9700cx I/O module has been replaced. Change the firmware of the I/O
modules to the version included in the X9720 Network Storage System:
a. Identify the serial number of the array using the command:
exds_stdiag
b. Run the X9700cx I/O module firmware update command:
# /opt/hp/mxso/firmware/exds9100cx_scexe –s
The command will pause to gather the system configuration, which can take several minutes
on a large system. It then displays the serial number of an array and asks if it should be
updated. If the serial number displayed is not the array to be updated, select N for “no.”
The command will continue to display serial numbers. When it reaches the desired array,
select Y to update the firmware.
NOTE:
If you reply Y to the wrong array, let the command finish normally. This can do no
harm since I/O has been suspended as described above (and the I/O modules should
already be at the level included in the X9720 Network Storage System).
c. After the array has been flashed, you can exit the update utility by entering q to quit.
d. Press the power buttons to power off the affected X9700c and X9700cx.
e. Re-apply power to the capacity block. Power on the X9700cx first, then the associated
X9700c. The firmware update occurs during reboot, so the reboot could take longer than
usual (up to 25 minutes). Wait until the seven-segment display of all X9700c enclosures goes
to the “on” state before proceeding. If the seven-segment display of an X9700c has not
returned to "on" after 25 minutes, power cycle the complete capacity block again.
12. Run the exds_stdiag command to verify the firmware version. Check that the firmware is the
same on both drawers (boxes) of the X9700cx. Following is an example of exds_stdiag output:
In the above example, the array serial number (box 1) is SGA830000M. The firmware level on
box 2 (left drawer of X9700cx) is 1.28. The firmware level on box 3 (right drawer) is 2.03. This
is unsupported because the firmware levels are not the same—the firmware must be updated as
described in step 11.
13. Mount the file systems that were unmounted in step 6 using the X9000 management console.
