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:

Procedure 1.

Upgrade HAFM software on the HAFM Server/Appliance to 07.01.00 (minimum).

Download ﬁrmware 05.02.00-13 by selecting Firmware Library from the Product Manager

Maintenance menu.

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.

Using the Product Manager, execute a CTP swap:

From the Product/Element Manager Hardware view, verify that an amber LED indicator is

not displayed for either CTP card.

Right-click the CTP card you believe to be active, and then select FRU Properties. Verify that

it is the active CTP card.

Right-click the active CTP card and select Switchover.

The Director loses its Ethernet connection for a short time during the switchover process.

When switchover occurs, the green LED illuminates on the backup CTP card to indicate that

it is now the active card.

Upgrade the ﬁrmware to 05.02.00-13 on each Director by selecting Send in the Firmware Library

dialog box.

Upgrading ﬁrmware on an Edge Switch from 04.xx.xx to 05.xx.xx

An issue has been identiﬁed in release 04.xx.xx if the contents of the NVRAM on the 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 CTP has corrupted contents, the ﬁrmware load can cause the

conﬁguration to reset to factory defaults, which can cause a system outage.

Edge switch products already running 05.01.00 or later continually validate the NVRAM conﬁguration,

so risk of an outage is extremely low. For Edge Switch products running an earlier version of ﬁrmware,

the risk of an outage increases due to the NVRAM issue. If an outage compromises system integrity, HP
