•

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
