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 modecannotbedonewiththe
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, H P recommends that you downgrade
theunitbeforeinstallingitintothefabric.
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 e arlier than 06.02.00, ISLs
could become segmented if there are any other switches in the fabric o perating 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 d isplays 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 d ownload 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 soft ware to
07.01.00-9 minimum, if you are using the notebook HAFM server to m a nage 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 N umber 320908-B22, for
owners of license for previous versions. This HAFM upgrade is also available on the
following HP web site: h
