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 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 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 09.02.00 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 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 08.xx.xx or later before upgrading to 09.02.00. If a
switch is operating with a firmware level earlier than 08.xx.xx, you must upgrade to 08.02.00
before installing 09.02.00
• 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 07.01.03 to or from 08.02.00, or
08.02.00 to or from 09.02.00. 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.
• If upgrading firmware requires an upgrade from 04.xx.xx to 05.xx.xx in the process, there
are special considerations, as described in,
to 05.xx.xx" on page 11.
• If upgrading firmware requires an upgrade from 06.xx.xx in the process, upgrade from 06.xx.xx
to 07.01.03. Firmware 07.01.03 includes a fix to an issue that can occur when firmware is
upgraded from 06.xx.xx to 07.xx.xx under very specific conditions. Other versions of 07.xx.xx
should not be used in the upgrade process.
• If upgrading firmware requires an upgrade from 07.xx.xx in the process, upgrade from 07.xx.xx
to 08.02.00. Firmware 08.02.00 includes a fix to a issue that can occur when firmware is
upgraded from 07.xx.xx to 08.xx.xx for the Edge Switch 2/24 and Edge Switch 2/12. Other
versions of 08.xx.xx should not be used in the upgrade process.
• A small number of early-shipped Surestore Director FC-64 units may display one of the following
messages when upgrading to firmware 05.02.00-13:
• HAFM—Firmware cannot be loaded due to insufficient CTP memory.
• HAFM Basic—File System Error:
version.
This occurs only in certain units with CTP cards. Units with CTP2 cards do not have this issue.
If you receive one of these messages during the upgrade, the firmware upgrade has failed but the
unit continues to run with the existing firmware. The upgrade process checks for sufficient memory
before activating the new firmware image. The firmware upgrade cannot complete without sufficient
memory. Contact HP Customer Support if you receive this message.
• Some customer environments use application or host software that is affected by the restart
of the Director CTP during a HotCAT download operation. Applications that rely on inband
