HP 316095-B21 - StorageWorks Edge Switch 2/24 Freigabemitteilung

NOTE:

The following HP firmware versions are considered to be within one functional release:

09.08.03, 09.08.01, 09.07.02

09.06.02

09.03.00, 09.02.00, 09.00.00

08.02.00, 08.01.01, 08.01.00

07.01.03, 07.01.02, 07.00.00

If you use HAFM Basic for upgrades and downgrades, and the release version rule is not followed,

errors will occur and there may be a disruption to attached devices.

If upgrading firmware requires an upgrade from 04.xx.xx to 05.xx.xx, there are special consider-

ations, as described in

If upgrading firmware requires an upgrade from 06.xx.xx, upgrade from 06.xx.xx to 07.01.03.

Firmware 07.01.03 includes a fix to an issue that can occur under very specific conditions when

firmware is upgraded from 06.xx.xx to 07.xx.xx . Other versions of 07.xx.xx should not be used

in the upgrade process.

If upgrading firmware requires an upgrade from 07.xx.xx, 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 Surestore Director FC-64 units that were shipped early may display one of the

following messages during the process of upgrading to firmware 05.02.00-13:

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

HAFM Basic—File System Error: Insufficient memory for new firmware

version.

This occurs only in certain units with control processor (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. Before activating the new firmware image, the

upgrade process found that there was insufficient memory to complete the upgrade. 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 management

servers are especially prone to problems caused by processor restart. For example, an application

may be configured to poll the Edge Switch or Director at regular intervals. The polling process

could occur during a restart period, causing the application software to react adversely. As a

solution, before the upgrade shut down the applications driving inband requests, and then restart

the applications after the upgrade is complete.

Upgrading firmware on a Director from 04.xx.xx to 05.xx.xx

An issue has been identified in release 04.xx.xx if the contents of the nonvolatile random access

memory (NVRAM) on the active CTP are corrupted. Once the configuration has been loaded, this

corruption is not detected until an IPL/IML, power cycle, or firmware code load. If the NVRAM on the

active CTP has corrupted contents, the firmware load can cause the configuration to reset to factory

defaults, which can cause a system outage. By using the following procedure to upgrade firmware,

configuration is preserved and a system outage is avoided. This issue has been resolved with firmware

05.02.00-13 and later.
