If upgrading firmware requires an upgrade from 04.xx.xx to 05.xx.xx in the process,
there are special considerations, as detailed in the section,
director from 04.xx.xx to
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:
firmware 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:
Step 4 of the following procedure is not required if you are upgrading from 05.xx.xx or
later.
To safely upgrade firmware on a Director:
1.
Upgrade HAFM software on the HAFM Server/Appliance to 07.01.00 (minimum).
05.xx.xx.
