If you get one of these messages during the upgrade, the firmware upgrade failed, but the unit continues working with the existing firmware 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.

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 nonvolatile storage (NVRAM) on the CTP become 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 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 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
To safely upgrade firmware on a edge switch, perform the following:
1.Upgrade HAFM software on the HAFM server/appliance to 07.01.00 (minimum).
2.Download firmware
3.Back up the edge switch configuration using the Backup & Restore Configuration option under the Product Manager Maintenance menu.
4.Upgrade the firmware to
Considerations for downgrading the version of firmware
Directors or edge switches are not required to be offline before performing a firmware 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 HP StorageWorks Edge Switch Element Manager User Guide for more information. EWS also provides an option to print or save product configuration to a file. Refer to your HP StorageWorks Embedded Web Server User Guide for more information.
