HP StorageWorks Director and Edge Switch release notes (5697-8176, April 2009)

Firmware installation

This section includes firmware installation information.

Prerequisites for installing and using firmware 09.09.02

Consider the following prerequisites for firmware 09.09.02:

• HAFM should be at the minimum level before installing the new firmware. Before upgrading to

firmware 09.09.02, EFCM must be at 09.07.00 or later if you are using EFCM to manage your

Directors or Edge Switches. EFCM is not required, but is recommended for managing your Directors

or Edge Switches.

NOTE:

HAFM is not required for operating hardware products; however, it is recommended for managing

your Directors or Edge Switches.

• HAFM is not able to configure the McDATA 4 Gb/s Intrepid 6000 QPM (QPM) when installed

into a Director 2/64. The QPM can be configured using HAFM Basic or the CLI. McDATA EFCM

9.0 or later is capable of configuring the QPM when installed into a Director 2/64.

• If you are using HAFM to upgrade firmware, an Edge Switch 2/24 must be managed with HAFM

08.08.00 or higher before upgrading to firmware 08.xx.xx or later. If you upgrade to firmware

08.xx.xx or later using an HAFM release earlier than 08.08.00, the firmware upgrade may fail.

Firmware 08.01.00 introduced slightly more processor utilization, which can cause the download

to occasionally exceed HAFM's timeout. As an alternative to HAFM, use the switch's HAFM Basic

interface (formerly EWS) to upgrade firmware.

• Firmware upgrades or downgrades should not be performed using HAFM Basic from Internet Ex-

plorer 5.00.3315.1000x. If this operation is performed, the download operation may not complete

and may eventually time out, leaving the switch with the previous version of firmware.

• All Edge Switches and Directors in the same fabric should have the same firmware level installed.

Although products can coexist in a fabric running different levels of firmware, all products must

be at the same major functional release level.

Upgrading from an earlier version of firmware

Upgrading to firmware 09.09.02 is nondisruptive to attached devices. The Director or Edge Switch

is not required to be offline before performing an upgrade operation. If there are any limitations to

performing an upgrade operation, they are clearly identified.

Consider the following when upgrading firmware:

• Before upgrading firmware, HP recommends that you back up the Director or Edge Switch config-

uration. See the HP StorageWorks Director Element Manager user guide for more information.

HAFM Basic also provides an option to print or save product configuration to a file. See the HAFM

Basic user guide for more information.

• All products must be running firmware 09.07.02 or later before upgrading to 09.09.02. If a

switch is operating with a firmware level earlier than 09.07.02, you must upgrade to 09.07.02

or 09.08.01 before installing 09.09.02.

• Upgrades and downgrades are supported only within a functional release, such as 09.07.02 to

09.08.01, or from one functional release to the next, such as from 09.03.00 to or from 09.06.02,

or 09.06.02 to or from 09.08.01.
