8 Installing and maintaining firmware In this chapter, you will see references to optional port blades installable in the SAN Director 4/256: • Port blades contain Fibre Channel ports. • FC blades contain only Fibre Channel ports: FC4-16, FC4-32, FC4-48. • AP blades are "intelligent" blades: B-Series Multi-protocol (MP) Router blade and FC4-16IP blade • CP blades have a control processor (CP) used to control the entire switch; they can be inserted only into slots 5 and 6. IMPORTANT: At the time of this document's release, HP does not support the FC4-16IP blade. Consult http://www.hp.com for the latest, updated information. About the firmware download process The firmwareDownload command downloads uncompressed switch firmware from an FTP server to the switch's nonvolatile storage area. In the SAN Director 2/128 and 4/256 SAN Director, this command (when not using any options flags) by default downloads the firmware image to a standby CP, if there is one, to prevent disruption to application services. This operation depends on high-availability (HA) support. If HA is not available, you can upgrade the CPs one at a time, using the -s option. CAUTION: To ensure non-disruptive downloads on non-Director-class switches, please ensure that the firmwareDownload is completed successfully on each switch in a serial fashion. Enter the firmwareDownloadStatus command on the switch before moving on to the next switch. Fixed-port models and each CP blade of the SAN Director 2/128 and 4/256 SAN Director models have two partitions of nonvolatile storage areas (a primary and a secondary) to store two firmware images. The firmwareDownload command always loads the new image into the secondary partition and swaps the secondary partition to be the primary. It then reboots the partition and activates the new image. Finally, it performs the firmwareCommit procedure automatically, to copy the new image to the other partition. If you are using a 4/256 SAN Director with one or more AP blades: The Fabric OS automatically detects mismatches between the active CP firmware and the blade's firmware. By the end of the firmware download process the active CP and the B-Series MP Router blade will be running the same version of firmware. Upgrading and downgrading firmware "Upgrading" means installing a newer version of firmware; "downgrading" means installing an older version of firmware. In most cases, you will be upgrading firmware; that is, installing a newer firmware version than the one you are currently running. However, some circumstances might require installing an older version; that is, downgrading the firmware. The procedures in this section assume that you are upgrading firmware, but they work for downgrading as well, provided the old and new firmware versions are compatible. Also, always reference the latest Fabric OS release notes for updates that may exist regarding downgrades under particular circumstances. Using the CLI (or Web Tools), you can upgrade the firmware on one switch at a time. You can use the optionally licensed Fabric Manager software tool to upgrade firmware simultaneously on multiple switches. For more details on Fabric Manager and other licensed software tools, go to the HP web site, http://www.hp.com. Fabric OS 5.2.x administrator guide 153

Installing and maintaining firmware

In this chapter, you will see references to optional port blades installable in the SAN Director 4/256:

•

Port blades contain Fibre Channel ports.

•

FC blades contain only Fibre Channel ports: FC4-16, FC4-32, FC4-48.

•

AP blades are “intelligent” blades:

B-Series Multi-protocol (MP) Router blade

and FC4-16IP blade

•

CP blades have a control processor (CP) used to control the entire switch; they can be inserted only into

slots 5 and 6.

IMPORTANT:

At the time of this document’s release, HP does not support the FC4-16IP blade. Consult

http://www.hp.com

for the latest, updated information.

About the firmware download process

The

firmwareDownload

command downloads uncompressed switch firmware from an FTP server to the

switch’s nonvolatile storage area.

In the SAN Director 2/128 and 4/256 SAN Director, this command (when not using any options flags) by

default downloads the firmware image to a standby CP, if there is one, to prevent disruption to application

services. This operation depends on high-availability (HA) support. If HA is not available, you can upgrade

the CPs one at a time, using the

-s

option.

CAUTION:

To ensure non-disruptive downloads on non-Director-class switches, please ensure that the

firmwareDownload

is completed successfully on each switch in a serial fashion. Enter the

firmwareDownloadStatus

command on the switch before moving on to the next switch.

Fixed-port models and each CP blade of the SAN Director 2/128 and 4/256 SAN Director models have

two partitions of nonvolatile storage areas (a primary and a secondary) to store two firmware images. The

firmwareDownload

command always loads the new image into the secondary partition and swaps the

secondary partition to be the primary. It then reboots the partition and activates the new image. Finally, it

performs the

firmwareCommit

procedure automatically, to copy the new image to the other partition.

If you are using a 4/256 SAN Director with one or more AP blades:

The Fabric OS

automatically detects mismatches between the active CP firmware and the blade’s firmware. By the end of

the firmware download process the active CP and the B-Series MP Router blade will be running the same

version of firmware.

Upgrading and downgrading firmware

“Upgrading” means installing a newer version of firmware; “downgrading” means installing an older

version of firmware.

In most cases, you will be

upgrading

firmware; that is, installing a newer firmware version than the one you

are currently running. However, some circumstances might require installing an older version; that is,

downgrading

the firmware. The procedures in this section assume that you are upgrading firmware, but

they work for downgrading as well, provided the old and new firmware versions are compatible. Also,

always reference the latest

Fabric OS release notes

for updates that may exist regarding downgrades

under particular circumstances.

Using the CLI (or Web Tools), you can upgrade the firmware on one switch at a time. You can use the

optionally licensed Fabric Manager software tool to upgrade firmware simultaneously on multiple switches.

For more details on Fabric Manager and other licensed software tools, go to the HP web site,

ttp://www.hp.com
