HP 316095-B21 - StorageWorks Edge Switch 2/24 Release Note page 12

Prerequisites for installing and using firmware 08.01.00
If you are using HAFM, firmware 08.01.00 requires HAFM 07.01.00 or later, check
with HP Customer Support for the latest shipping version of HAFM. HAFM should 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 8.08.00 or higher before upgrading to firmware 08.01.00. If you upgrade
to firmware 08.01.00 using an HAFM release before 8.08.00, 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. In this situation, use the
switch's HAFM Basic interface (formerly EWS) to upgrade firmware. HAFM 8.08.00
will be available early December 2005.
Firmware upgrades or downgrades should not be performed via HAFM Basic using
Internet Explorer 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.
NOTE:
HAFM is not required for operating hardware products using the firmware.
All Directors and Edge Switches 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 08.01.00 is nondisruptive to attached devices. The Director or
Edge Switch is not required to be offline before performing an upgrade operation.
Limitations to upgrades are clearly identified if there are any limitations to performing
the operation.
Before upgrading firmware, HP recommends that you back up the Director or Edge
Switch configuration. 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 07.01.03 or later before upgrading to 08.01.00.
If a switch is operating with a firmware level earlier than 07.01.03, you must upgrade
to 07.01.03 before installing 08.01.00.
Upgrades and downgrades are 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 06.02.00 to 07.01.03
or 07.01.03 to 08.01.00. If HAFM Basic is used for upgrades and downgrades, and
this rule is not followed, errors occur and there may be a disruption to attached devices.
