172 Installing and maintaining firmware
Overview of the firmware download process on directors
The following summary describes the default behavior of the firmwareDownload command (without
options) on the 4/256 SAN Director and DC Director. After you enter the firmwareDownload
command on the active CP blade the following actions occur:
1. The standby CP blade downloads firmware.
2. The standby CP blade reboots and comes up with the new Fabric OS.
3. The active CP blade synchronizes its state with the standby CP blade.
4. The active CP blade forces a failover and reboots to become the standby CP blade.
5. The new standby CP blade (the active CP blade before the failover) downloads firmware.
6. The new standby CP blade reboots and comes up with the new Fabric OS.
7. The new active CP blade synchronizes its state with the new standby CP blade.
8. The firmwareCommit command runs automatically on both CP blades.
TIP: After you start the process, do not enter any disruptive commands (such as reboot) that will interrupt
the process. The entire firmware download and commit process takes approximately 15 minutes. If there is
a problem, wait for the time-out (30 minutes for network problems). Disrupting the process can render the
switch inoperable and require you to seek help from HP.
Do not disconnect the switch from power during the process because the switch could become inoperable
upon reboot.
4/256 SAN Director and DC Director firmwareDownload procedure
There is only one logical switch address for the 4/256 SAN Director and DC Director.
NOTE: By default, the firmwareDownload command automatically upgrades both the active and
standby CP on the 4/256 SAN Director. It also automatically upgrades both the active and the standby CP
and all co-CPs on the CP blades. It automatically upgrades all AP blades in the 4/256 SAN Director and
DC Director using auto-leveling.
To upgrade firmware on 4/256 SAN Director and DC Director (including blades):
1. Verify that the FTP or SSH server is running on the host server and that you have a user ID on that
server.
2. Obtain the firmware file from the HP website at http://www.hp.com
and store the file on the FTP or
SSH server.
3. Unpack the compressed files preserving directory structures.
The firmware is in the form of RPM packages with names defined in a .plist file. The .plist file contains
specific firmware information and the names of packages of the firmware to be downloaded.
4. Connect to the switch and log in as admin.
5. Use the firmwareShow command to check the current firmware version on connected switches.
Upgrade the firmware, if necessary, before proceeding with upgrading this switch.
See ”Checking connected switches” on page 168
6. Enter the haShow command to confirm that the two CP blades are synchronized. In the following
example, the active CP blade is CP0 and the standby CP blade is CP1:
switch:admin> hashow
Local CP (Slot 5, CP0): Active, Warm Recovered
Remote CP (Slot 6, CP1): Standby, Healthy
HA enabled, Heartbeat Up, HA State synchronized
