HP 316095-B21 - StorageWorks Edge Switch 2/24 Release Note page 12

• Upgrades and downgrades are supported only from one major release to the next, such as from
08.xx.xx 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.
• Before downgrading to a release prior to 07.00.00, there can be only one user assigned as
Administrator and one user assigned as Operator for HAFM Basic and the CLI. If additional users
were created, you must delete them before downgrading. However, firmware 07.xx.xx does
not allow the last user with Administrator rights in HAFM Basic or the CLI to be deleted. If no
Operator user exists, firmware 07.xx.xx automatically creates one for each interface during the
downgrade. If more than one Administrator and/or one Operator exists for HAFM Basic and/or
the CLI, when attempting to downgrade, you are prompted to delete one of them first.
• When downgrading to a release earlier than 07.00.00, any modifications to the port RX
BB_Credit settings using the new enhanced port configuration capability must be changed back
to a configuration supported by older firmware. This enables the configuration to comply with the
previous release's configuration database. Firmware 07.xx.xx services verify compatibility and
prevent downloads until the configuration conflict is resolved.
• Downgrading to release 06.xx.xx with the Preferred Path feature configured can cause loss of
this function. HP recommends that Preferred Path be disabled before downgrading. To do this,
deselect the Enable Preferred Path check box in the Configure Preferred Paths dialog box.
• The Director 2/140 and Edge Switch 2/24 cannot be downgraded to a version earlier than
04.01.00. The Edge Switch 2/12 cannot be downgraded to a version earlier than 05.05.00.
Second-generation Edge Switch 2/12 and Edge Switch 2/24 switches cannot be downgraded to
a version earlier than 06.02.00. The Sphereon 4700 or 4400 switches cannot be downgrade
to a version earlier than 08.00.00.
• If a Director 2/140 in a multiswitch fabric is downgraded to a version earlier than 06.02.00, ISLs
can become segmented if there are any other switches in the fabric operating with a firmware
version earlier than 06.01.00. To prevent this situation, downgrade all Director 2/140s in the
fabric to 06.01.00 before downgrading any products in the fabric to 05.xx.xx. This problem only
exists with Director 2/140s in the fabric. HAFM displays a warning message if a downgrade
from 06.02.00 is attempted, but you can continue with the downgrade if desired.
NOTE:
A warning message appears when downgrading any model from 06.02.00; however the message
applies only to downgrade operations for the Director 2/140.

HAFM upgrade required for firmware 09.06.02
Consider the following HAFM requirements for firmware 09.06.02:
• To upgrade to firmware 09.06.02, you must first upgrade the HAFM software to 07.01.00-9
if you are using the Notebook HAFM Server to manage the Director or Edge Switch. The
HAFM software is contained on the HP StorageWorks HA-Fabric Manager Documentation and
Software CD (Part Number 516-000024-710). This HAFM is available on the HP website
http://h18006.www1.hp.com/storage/networking/index.html. Select Retired Products and
navigate to your switch model, and then to Download drivers and software.
• If you are using the 1U rack-mount HAFM Appliance to manage the Director or Edge Switch,
the minimum HAFM version required is 07.02.00-9, which is the minimum version installed. This
