FW 07.01.02/HAFM SW 08.06.00 HP StorageWorks HA-Fabric Manager Release Notes (AA-RUR6G-TE, August 2005)

Some customer environments use application or host software that is affected by the

restart of the d irector 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 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 n onvolatile storage

(NVRA M ) on the CTP become c orrupted. Once the conﬁg uration has been loaded,

this corruption is not detected until an IPL/IML, power cycle, or ﬁrmware code load.

If the NVR A M i

n the CTP has corrupted contents, the ﬁrmwar e load can cause the

conﬁguration to reset to factory defaults, which could 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 recommends that the edge switch ﬁrmware

upgrade be a scheduled maintenance action that anticipates the failure of switch

connectivity. This issue was corrected with ﬁrmware 05.02.00-13 and later.

To safely

upgrade ﬁrmware on a e dge switch, perform the following:

1. Upgrade

HAFM software on the HAFM server/appliance to 07.01.00 (minimum).

2. Downlo

ad ﬁrmware 05.02.00-13 using the Firmware Library option under the

Product Manager Maintenance m enu.

3. Backuptheedgeswitchconﬁgu ration using the Backup & Restore Conﬁguration

option under the Product Manager Maintenance menu.

4. Upgrade the ﬁrmware to 05.02.00-13 on each edge switch using the Send option

on th

e Firmware Library dialog box.

Upgrading ﬁrmwareonadirectorfrom04.xx.xxto05.xx.xx

An issue has been identiﬁed in release 04.xx.xx if the contents of the n onvolatile storage

(NVRAM) on the active CTP become corrupted. Once the con ﬁguration 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 ﬁrmw are 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.
