Downgrades directly to 05.03.01 from 06.xx.xx is not concurrent when the second-generation Edge Switch 2/24 is configured in Open Fabric operating mode. In other words, downgrades in Open Fabric mode cannot be done with the second-generation Edge Switch 2/24 online without disrupting port operations. Since second-generation Edge Switch 2/24 switches cannot be downgraded earlier than 05.03.01, they must be configured in Homogeneous Fabric Interoperability mode to remain concurrent. If this process is not followed, I/O through the switch may be significantly disrupted or stopped. Recovery for this situation is accomplished by reactivating the current zone set.
If you are installing a new or replacement second-generation Edge Switch 2/12 or Edge Switch 2/24 into an existing 05.xx.xx fabric, HP recommends that you downgrade the unit before installing it into the fabric.
Downgrading to 05.05.00 is supported only on first-generation Edge Switch 2/12 switches. Second-generation Edge Switch 2/12 switches can be downgraded only to
05.05.01.Second-generation Edge Switch 2/24 switches can be downgraded only to 05.03.01.
If a Director 2/140 in a multiswitch fabric is downgraded earlier than 06.02.00, ISLs could 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:
The warning message is displayed when downgrading any model from 06.02.00, but only applies to downgrade operations for the Director 2/140.
Firmware downgrades should not be performed using EWS and Internet Explorer v5.00.3315.1000x. If this operation is performed, the download operation may not complete and may eventually time-out leaving the switch with the previous version of firmware.
HAFM upgrade required for firmware version 07.xx.xx
To upgrade to firmware 07.01.02-4, you must first upgrade the HAFM software to 07.01.00-9 minimum, 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 516-000024-820). An upgrade kit to HAFM 07.01.00-9 is also available, Part Number 320908-B22, for owners of license for previous versions. This HAFM upgrade is also available on the following HP web site: http://h18006.www1.hp.com/storage/saninfrastructure.html
