Considerations for downgrading the version of firmware

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

limitations to per forming the operation.

Before downgrading firmware, it is highly recommended that you back up the director

or edge switch configuration. Refer to your HP StorageWorks Edge Switch Element

Manager User Guide for more information. EWS also provides an option to print or

save product configuration to a file. Refer to your HP StorageWorks Embedded Web

Server User Guide for more information.

Before downgrading below 07.00.00-84, there can only be one user assigned access

rights as Administrator and one user assigned as Operator for Embedded Web Server

and CLI. If additional users were created, you have to delete them b efore downgrading.

Firmware 07.00.00-84 does not allow the last user with Administrator rights in

Embedded Web Server or CLI to be deleted. If no O perator user exists, firmware

07.00.00-84 aut

omatically creates one for each interface during the downgrade. If more

than one Adminis

trator and/or one O perator exists for Embedded Web Server and/or

CLI, when attempting to downgrade you are prompted to delete one of them first.

When downgrading to a release prior to 07.00.00-84, 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 is necessary

to allow the configuration to comply with previous releases’ configuration da tabase.

Firmware 07.00.00-84 services verify compatibility and prevent downloads until the

configuration conflict is resolved.

For procedures to

download firmware to the switch or director using the HAF M Element

Manager interfa

ce or EWS interface, refer to the following:

• The switch or director Installation and Service Manual. This publication

provides complete procedures for obtaining firmware from the HP web site and

downloading firmware to the switch o r director using HAFM.

• The switch or director Element Manager online help and User Manual. These

includes instructions for downloading firmware to the switch or director using the

HAFM interface.

• EWS User Manual. This provides procedures for downloading firmware to

the switch or director.

• EWS online help. This provides procedures for downloading firmware to the

switch or director.

Downgrading directly to a release before 06.00.00 from 07.00.00-84 is not allowed.

To downgrade to a release before 06.00.00, you must first downgrade to 06.YY.ZZ.
