220 Installing and maintaining firmware
During the upgrade process, the director fails over to its standby CP blade and the IP address for the
enterprise-class platform moves to that CP blade's Ethernet port. This may cause informational ARP address
reassignment messages to appear on other switches in the fabric. This is normal behavior, because the
association between the IP addresses and MAC addresses has changed.
IMPORTANT: To successfully download firmware, you must have an active Ethernet connection on each of
the CPs.
Enterprise-class platform firmware download process overview
The following summary describes the default behavior of the
firmwareDownload
command (without
options) on an HP StorageWorks 4/256 SAN Director, an HP StorageWorks DC SAN Backbone Director
and HP StorageWorks DC04 SAN Director Switch enterprise-class platforms. 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.
CAUTION: 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 your switch service provider .
Do not disconnect the switch from power during the process because the switch could become inoperable
upon reboot.
Upgrading firmware on enterprise-class platforms (including blades)
There is only one Logical Switch address for the HP StorageWorks 4/256 SAN Director, the HP
StorageWorks DC SAN Backbone Director and HP StorageWorks DC04 SAN Director Switch platforms.
NOTE: By default, the
firmwareDownload
command automatically upgrades both the active and
standby CP on the HP StorageWorks 4/256 SAN Director. It also automatically upgrades both the active
and the standby CP and all co-CPs on the CP blades in the HP StorageWorks DC SAN Backbone Director
and HP StorageWorks DC04 SAN Director Switch. It automatically upgrades all AP blades in the HP
StorageWorks 4/256 SAN Director, the HP StorageWorks DC SAN Backbone Director, and HP
StorageWorks DC04 SAN Director Switch platforms using auto-leveling.
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 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.
