The upgrade process checks for sufficient memory before activating the new firmware
image. The firmware upgrade does not complete without sufficient memory. Please
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 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, 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 nonvolatile storage
(NVRAM) on the active CTP become 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 in the active CTP has corrupted contents, the firmware load can
cause the configuration to reset to factory defaults, which could cause a system outage.
By using the following procedure to upgrade firmware, configuration is preserved and a
system outage is avoided. This issue was corrected 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, perform the following:
1.
Upgrade HAFM software on the HAFM server/appliance to 07.01.00 (minimum).
2.
Download firmware 05.02.00-13 using the Firmware Library option under the
Product Manager Maintenance menu.
3.
Back up the director configuration using the Backup & Restore Configuration option
under the Product Manager Maintenance menu.
4.
Using the Product Manager, execute a CTP swap:
a.
From Product/Element Manager Hardware view, verify that an amber LED
indicator is not displayed for either CTP card.
b.
Right-click the CTP card you believe to be active. From the right-click pop-up
menu, choose FRU Properties. Verify that it is the active CTP card.
c.
Right-click the active CTP card and choose Switchover from the pop-up
menu.
The director loses its Ethernet connection for a short period during the
switchover process.
