Firmware installation

This section includes ﬁrmware installation information.

Prerequisites for installing and using ﬁrmware 09.00.00

Consider the following prerequisites for ﬁrmware 09.00.00:

• If you are using HAFM, ﬁrmware 09.00.00 requires HAFM 07.01.00 or later. This minimum

version lets you manage Edge Switches and Directors running 09.00.00 ﬁrmwar e. Howe ver, to

use all the new features and enhancements for ﬁrmware version 05.xx.xx and later, upgrade

HAFM to 08.09.01, which only runs on the HAFM Appliance (see Table 3).

• Check with HP Customer Support for the latest shipping version of HAFM. HAFM s hould be at the

minimum level before installing the new ﬁrmware.

• 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 utiliza tion, 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 per formed using HAFM Basic using Internet

Explorer 5.00.3315.1000x. If this operation is per formed, the download operation may not

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

NOTE:

HAFM is not required for operating hardware products using the 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 09.00.00 is nondisruptive to attached devices. The Director or Edge Switch is

not required to be off line before performing an upgrade operation. Limitations to upgrades are clearly

identiﬁed if there are any limitations to performing the operation.

Consider the following when upgrading ﬁrmware:

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

conﬁguration. See the HP StorageWorks Director Element M anager user guide for more

information. HAFM Basic also provides an o ption to print or save product conﬁguration to a ﬁle.

See the HAFM Basic user guide for more information.

• All products must be running ﬁrmware 08.xx.xx or later before upgrading to 09.00.00. If a

switch is operating with a ﬁrmware level earlier than 08.xx.xx, you must upgrade to 08.02.00

before installing 09.00.00

• Upgrades and downgrades a re supported only within a major release, such as 08.xx.xx to

08.xx.xx, or from one major release to the next, such as from 07.01.03 to 08.02.00, or 08. 02.00

to 09.00.00. If HAFM Basic is used for upgrades and downgrades, and this rule is not followe d,

errors occur and there may be a disruption to at tached devices.
