4. It is normal for the X9700c controller connected to the I/O module to reset itself. The seven-segment
display of the X9700c enclosure will no longer show “on,” and the X9700c controller will have
an amber warning light. If the I/O module had previously failed, the X9700c controller will
already be in this state.
5. Remove the I/O module.
6. Replace the I/O module (it will not engage with the disk drawer unless the drawer is fully pushed
in).
7. Re-attach the SAS cable. Ensure it is attached to the “IN” port.
8. Change the firmware of the I/O modules to the version included in the ExDS 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 a 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 ExDS 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. Disconnect all power cables from the X9700cx enclosure until the LEDs on the rear of the
unit extinguish. Reconnect the power cables to the enclosure.
f. 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.
9. 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 this 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. In addition, if exds_stdiag continues
to report that the firmware levels are below the recommended version, you must repeat the
firmware update process in its entirety starting at step 8 above until the firmware levels are correct.
