Validating The Firmware Download - HP AA979A - StorageWorks SAN Switch 2/8V Administrator's Manual

10. Restore firmware on the "new" standby CP
a. Wait one minute and start a telnet session on the new standby CP, which is the old active CP.
b. Enter the firmwareRestore command. The standby CP will reboot and the telnet session will
end. Both partitions will be made equal after several minutes.
c. Wait 5 minutes and log into the switch. Enter the firmwareShow command and verify that all
partitions have the original firmware.
If an AP blade is present: Blade partitions always contain the same version of the firmware on
both partitions (it does not keep two copies). The firmware is stored on the blade's compact flash
card and is always synchronized with the active CP's firmware. Thus, if you restore the active CP
firmware, the blade firmware is automatically downloaded to become consistent with the new CP
firmware (the blade firmware is basically restored).
Your system is now restored to the original partitions on both CPs. Make sure that servers using the fabric
can access their storage devices.
If you wish to upgrade a Director with only one CP in it, follow the procedures in
firmware on switches" on page 160. Note, however, that upgrading a Director with only one CP in it will
be disruptive to Fibre Channel traffic.

Validating the firmware download

Validate the firmware download by running the following commands: firmwareShow, nsShow,
nsAllShow, and fabricShow.
NOTE: When you prepared for the firmware download, you should have issued either the
supportShow (4.2.x or earlier) or supportSave (4.4.x or later) command. While you can issue the
command again and compare the outputs from before and after, be aware that it may take as long as 30
minutes for the command to execute. To save time, it is recommended that you use the commands listed
below, which are all are subsets of the supportSave output.
All of the connected servers, storage, and switches should be present in the output of these commands. If
there is a discrepancy, it is possible that a device or switch cannot connect to the fabric and further
troubleshooting is necessary.
firmwareShow
Displays the current firmware level on the switch. For Directors this command displays the firmware loaded
on both partitions (primary and secondary) for both CPs. HP recommends maintaining the same firmware
level on both partitions of each CP within the Director.
nsShow
(Optional) Displays all devices directly connected to the switch that have logged into the Name Server.
Make sure the number of attached devices after the firmware download is exactly the same as the number
of attached devices prior to the firmware download.
nsAllShow
(Optional) Displays all connected devices to a fabric. Make sure the number of attached devices after the
firmware download is exactly the same as the number of attached devices prior to the firmware download.
fabricShow
(Optional) Displays all switches in a fabric. Make sure the number of switches in the fabric after the
firmware download is exactly the same as the number of attached devices prior to the firmware download.
