HP StorageWorks Director and Edge Switch Release Notes (09.09.08) (5697-0720, October 2010)

Before downgrading firmware, HP recommends that you back up the Edge Switch or Director
configuration. See the Director or Edge Switch Element Manager user guide for more information.
EWS (HAFM Basic) provides an option to print or save the 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 0x60 before downgrading to a version
earlier than 09.00.00.
• WWN aliases will be disabled when downgrading firmware in any Edge Switch or Sphereon
switch to a version earlier than 09.01.00.
• Downgrading directly to a version earlier than 09.07.00 from 09.09.08 is not allowed. To
downgrade to a version 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 from 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 will occur and there may be a disruption to attached devices.
