HP StorageWorks Director and Edge Switch Release Notes (09.09.08) (5697-0720, October 2010)

NOTE:
The following HP firmware versions are considered to be within one functional release:
• 09.09.08, 09.09.06, 09.09.05, 09.09.03, 09.09.02, 09.09.00
• 09.08.03, 09.08.01, 09.07.02

• 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 “Upgrading firmware on a Director from 04.xx.xx to 05.xx.xx” on page 11.
• 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, upgradehahm from 07.xx.xx to
08.02.00. Firmware 08.02.00 includes a fix to an 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.
• 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 firmware 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, the
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,
the configuration is preserved and a system outage is avoided. This issue has been resolved with
firmware 05.02.00-13 and later.
NOTE:
You must have maintenance authorization rights to access the HAFM Product/Element Manager menu
options used in this procedure.
To safely upgrade firmware on a Director:
1. Upgrade the HAFM software on the HAFM Server/Appliance to 07.01.00 (minimum).
