Testing firmware The standby CP reboots and the current session ends. After several minutes, both partitions should have the same Fabric OS version. c) Wait five minutes and log in to the Director. d) Enter firmwareshow and verify that all partitions have the original firmware. Your system is now restored to the original partitions on both CPs. You should confirm that all the servers using the fabric can access their storage devices. Refer to Validating a firmware installation on page 31 for information on this task. If an FX8-24 blade is installed (Brocade DCX 8510 only): Blade partitions must always contain the same version of the firmware on both partitions. 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 (autoleveled) to become consistent with the new CP firmware (the blade firmware is restored). If you want to upgrade a Director that has only one CP installed, follow the procedures in Testing and restoring firmware on switches on page 33. Be aware that upgrading a Director with only one CP is disruptive to switch traffic. Test-driving a new firmware version on a Director This example shows how you might install a firmware version to "test drive" it without either overwriting the version you are currently using or rebooting your active CP. It is written at a moderately high level of abstraction, so you may need to look at the more detailed steps above if you have questions. 1. Enter firmwaredownload -sn to download the firmware to the standby CP without committing it. 2. Reboot the standby CP. 3. Enter hafailover on the active CP to cause the standby CP to come up as the active CP with the "test" firmware active. 4. Run tests as desired on the new firmware (active CP). 5. Once you have completed your testing, you have two choices: ∙ Option 1: "My tests are finished on the new firmware, but I want to go back to what I had before." 1. Enter hafailover on the active CP to get back to the original CP (running the original firmware). 2. Enter firmwarerestore on the standby CP. This will reboot the standby, swap the partitions and then run commit on the standby CP. ∙ Option 2: "My tests are finished on the new firmware, and I want to install it fully." 1. Enter firmwaredownload -sb on the current standby CP (with old code) This loads new firmware, reboots and then commits the firmware on standby. 2. Enter firmwarecommit on the current active CP (with new code). You are now done and both CPs have latest firmware committed and active. Both options are non-disruptive to Director traffic.

Test-driving a new firmware version on a Director
This example shows how you might install a firmware version to “test drive” it without either overwriting the version you are currently
using or rebooting your active CP. It is written at a moderately high level of abstraction, so you may need to look at the more detailed
steps above if you have questions.
1.
Enter
firmwaredownload -sn
to download the firmware to the standby CP without committing it.
2.
Reboot the standby CP.
3.
Enter
hafailover
on the active CP to cause the standby CP to come up as the active CP with the “test” firmware active.
4.
Run tests as desired on the new firmware (active CP).
5.
Once you have completed your testing, you have two choices:
∙
Option 1:
“My tests are finished on the new firmware, but I want to go back to what I had before.”
1.
Enter
hafailover
on the active CP to get back to the original CP (running the original firmware).
2.
Enter
firmwarerestore
on the standby CP.
This will reboot the standby, swap the partitions and then run commit on the standby CP.
∙
Option 2:
“My tests are finished on the new firmware, and I want to install it fully.”
1.
Enter
firmwaredownload -sb
on the current standby CP (with old code)
This loads new firmware, reboots and then commits the firmware on standby.
2.
Enter
firmwarecommit
on the current active CP (with new code).
You are now done and both CPs have latest firmware committed and active.
Both options are non-disruptive to Director traffic.
