HP AARTDZHTE/958000284008 manual Prerequisites for installing and using firmware

Prerequisites for installing and using firmware 07.01.02

If you are using HAFM, firmware 07.01.02 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.

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 may co-exist 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 07.01.02-4 is non-disruptive 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, it is highly recommended that you back up the director or edge switch configuration. Refer to your HP StorageWorks Edge Switch Element Manager User Guide for more information. Embedded Web Server (EWS) also provides an option to print or save product configuration to a file. Refer to the HP StorageWorks Embedded Web Server User Guide for more information.

All products must be running firmware 06.00.00 or later before upgrading to 07.01.02-4. If a switch is operating with a firmware level earlier than 06.00.00, you must upgrade to 06.xx.xx before installing 07.01.02-4.

Upgrades and downgrades are supported only from one major release to the next, such as from 06.xx.xx to 07.01.02-4. If EWS 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 to firmware 06.02.00-22 requires you to upgrade from 04.xx.xx to 05.xx.xx in the process, there are special considerations, as detailed in the section, Upgrading firmware on an edge switch from 04.xx.xx to 05.xx.xx.

Asmall number of early-shipped Surestore Director FC-64 units may receive one of the following messages when they upgrade to firmware 05.02.00-13:

•HAFM—Firmware cannot be loaded due to insufficient CTP memory.

•EWS—File System Error: Insufficient memory for new firmware version.

This occurs only in certain units with CTP cards. Units with CTP2 cards do not have this issue.
