If you get one of these messages during the upgrade, the firmware upgrade failed, but
the unit continues working with the existing fi rmware without an interruption in service.
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.
Upgrading firmw
areonanedgeswitchfrom04.xx.xxto05.xx.xx
An issue has bee
nidentified in release 04.xx.xx if the co ntents of the nonvolatile storage
(NVRAM) on the
CTP become corrupted. Once the con figuration has be en loaded,
this corrupt
ion is not detected until an IPL/IML, power cycle, or firmware code load.
If the NVRAM in the CTP has corrupted contents, the firmware load can cause the
configuration to reset to factory defaults, which could cause a system outage.
Edge switch p
roducts already running 05.01.00 or later continually validate the NVRA M
configurati
on, so risk of an outage is extremely low. For edge switch products running an
earlier ver
sion of firmware, the risk of an outage increases due to the NVRAM issue. If
an outage c
ompromises system integrity, H P recommends that the edge switch firmware
upgrade b
e a scheduled maintenance action that anticipates the failure of switch
connect
ivity. This issue was corrected with firmware 05. 02.00-13 and later.
To safely upgrade firmware on a edge switch, per form the following:
1. Upgrade HA FM software on the HA FM 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. Backuptheedgeswitchconfiguration using the Backup & Restore Configuration
optio
n under the Product Manager Maintenance menu.
4. Upgr
ade the firmware to 05.02.00-13 on each edge switch using the Send option
on the Firmware Library dialog box.
Considerations for downgrading the version of firmware
Directors or edge switches are not required to be offlinebeforeperformingafirmware
downgrade o peration. Limitations to downgrades are clearly identified if there are any
limitations to performing the operation.
Before downgrading firmware, it is highly recommended tha t you back up the director
or edge switch configuration. Refer to your HP StorageWorks Edge Switch Element
ManagerUserGuidefor more information. EWS also provides an option to print or
save product configuration to a file. Refer to your HP StorageWorks Embedd ed Web
Server User Guide for more information.
