Upgrading firmw
areonanedgeswitchfrom04.xx.xxto05.xx.xx
An issue has bee
nidentified in release 04.xx.xx if the contents of the nonvolatile storage
(NVRAM) on the
CTP become corrupted. Once the configuration has been loaded,
this corrupt
ion is not detected until an I PL/IML, power cycle, or firmware code load.
If the NVRAM in the CTP has corrupted contents, the firmwar e load can cause the
configuration to reset to factory defaults, which could cause a sys tem 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, HP recommends tha t the edge switch firmware
upgrade b
e a scheduled maintenance action that anticipates the failure of switch
connect
ivity. This issue was corrected with firmwar e 05.02.00-13 and later.
To safely upgrade firmware on a e dge switch, perform the following:
1. Upgrade HA FM software on the HAFM server/appliance to 07.01.00 (minimum).
2. Download firmware 05.0 2.00-13 using the Firmware Library option under the
Product Manager Maintenance menu.
3. Backuptheedgeswitchconfiguration using the Backup & Restore Configuration
optio
n under the Product Ma nager Maintenance m enu.
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 operation. Limitations to downgrades are clearly identified if there are any
limitations to performing the operation.
Before downgrading firmware, it is highly recommended that you back up the director
or edge switch configuration. Refer to your H P StorageWorks Edge Switch Element
ManagerUserGuidefor more information. EWS also provides an option to print or
save product config uration to a file. Refer to your H P StorageWorks Embedded Web
Server User Guide for m ore information.
