This occurs only in certain units with CTP cards. Units with CTP2 cards do not have

this issue.

If you g et one of these messages during the upgrade, the firmware upgrade failed, but

the unit continues working with the existing firmware without an interruption in ser vice.

The upgrade process checks for sufficient memor y 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 o r host software that is affected by the

restart of the director CTP during a HotCAT download operation. Applications that rely

on inband management ser vers are especially prone to problems caused by processor

restart. For example, an app lication 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, p ower cycle, or firmware code

load. If the NVR AM in the active C TP has corrupted contents, the firmware load can

cause the configuration to reset to factory defaults, which cou ld 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 H AFM 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:
