HP StorageWorks Director and Edge Switch release notes (5697-8176, April 2009)

3. Back up the Edge Switch configuration by selecting Backup & Restore Configuration from the
Product Manager Maintenance menu.
4. Upgrade the firmware to 05.02.00-13 on each Edge Switch by selecting Send in the Firmware
Library dialog box.
Considerations for downgrading the firmware version
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 reasons for not performing
the operation.
Before downgrading firmware, HP recommends that you back up the Director or Edge Switch
configuration. Refer to the Director or Edge Switch Element Manager user guide for more information.
EWS (HAFM Basic) also provides an option to print or save product configuration to a file. See the
HAFM or EFCM Basic user guide for more information.
Consider the following when downgrading firmware:
• All installed QPM cards must be removed from the Director 2/140 if downgrading to a version
earlier than 09.00.00. All installed QPM cards must be removed from the Director 2/64 if
downgrading to a version earlier than 09.01.00.
• All trial PFE key features must be disabled before downgrading to a version earlier than 09.00.00.
• The domain ID offset must be set to the default value of 0x60 before downgrading to versions
earlier than 09.00.00.
• WWN Aliases will be disabled when downgrading firmware in any Edge Switch or Sphereon
switch to a release earlier than 09.01.00.
• Downgrading directly to a release earlier than 09.07.00 from 09.09.02 is not allowed. To
downgrade to a release earlier than 09.07.00, you must first downgrade to 09.08.01 or 09.07.02.
• Upgrades and downgrades are supported only within a functional release, such as 09.07.02 to
09.08.01, or from one functional release to the next, such as from 09.03.00 to 09.06.02, or
from 09.08.01 to 09.06.02. If HAFM Basic is used for upgrades and downgrades, and this rule
is not followed, errors occur and there may be a disruption to attached devices.
