HP 316095-B21 - StorageWorks Edge Switch 2/24 Release Note page 11

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 edge switch, perform the following:
1. Upgrade HAFM software on the HAFM server/appliance to 07.01.00
2. Download firmware 05.02.00-13 using the Firmware Library option under
3. Back up the edge switch configuration using the Backup & Restore
4. Upgrade the firmware to 05.02.00-13 on each edge switch using the Send
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.
Downgrading directly to a release before 05.00.00 from 06.02.00-22 is not
allowed. To downgrade to a release before 05.00.00, you must first downgrade to
05.YY.ZZ.
Upgrades and downgrades are supported only from one major release to the next,
such as from 05.xx.xx to 06.02.00-22. If EWS is used for upgrades and
downgrades, and this rule is not followed, errors occur and there may be a
disruption to attached devices.
