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

All products must be running firmware Version 04.00.00 or higher before
upgrading to Version 05.02.00-13.
All products must be running Version 02.00.00 or higher before upgrading to
Version 04.01.02-04. Upgrading to Version 04.01.02-04 from Version 02.00.00
or higher is nondisruptive to attached devices.
Firmware that predates the 01.03.00 or 01.04.00 firmware release must first be
upgraded to a 01.03.xx or 01.04.xx firmware version, and then upgraded to
Version 02.00.00 or higher, before the upgrade to Version 04.01.02-04 can be
completed.
A small number of early-shipped Surestore Director FC-64 units may receive one
of the following messages when they upgrade to Firmware V05.02.00-13:
This would only occur in certain units with CTP cards. Units with CTP2 cards
will not have this issue.
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 will not complete without
sufficient memory. Please contact HP customer support if you receive this
message.
Considerations for Downgrading the Version of Firmware
Directors and 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
edge switch or director configuration in the event that a failure should occur.
Refer to the switch or director Product Manager user guide for more information.
Embedded Web Server (EWS) also provides an option to print or save product
configuration to a file. Refer to the HP StorageWorks Embedded Web Server User
Guide for more information.
Downgrading directly to a version prior to 04.00.00 from Version 05.02.00-13 is
not allowed. To downgrade to a version before 04.00.00, you must first
downgrade to version 04.YY.ZZ.
