HP 316095-B21 - StorageWorks Edge Switch 2/24 Release Note page 11

• 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 1 1.
• 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
management servers are especially prone to problems caused by processor restart. For example,
an application may be configured to poll the Director or Edge Switch at regular intervals. The
polling process could occur during a restart period, causing the application software to react
adversely. As a solution, shut down those applications driving inband requests during a firmware
upgrade, and then restart the applications after upgrade completion.
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 non-volatile 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.
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 HAFM software on the HAFM Server/Appliance to 07.01.00 (minimum).
2. Download firmware 05.02.00-13 by selecting Firmware Library from the Product Manager
Maintenance menu.
3.
Back up the Director configuration by selecting Backup & Restore Configuration from the Product
Manager Maintenance menu.
NOTE:
Step 4 is not required if you are upgrading from 05.xx.xx or later.
