FW 07.01.02/HAFM SW 08.06.00 HP StorageWorks Edge Switch Release Notes (AA-RTDZH-TE, August 2005)

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 HAFM software is contained on the HP StorageWorks ha-fabric manager

documentation and software CD (Part Number 516-000024-720).

The previous minimum versions of HAFM allow you to manage directors or edge

switches running 07.01.02-4 ﬁrmware, but to be able to use all the new features and

enhancements, you need to upgrade HAFM to 08.06.00, which runs only on the 1U

rack-mount HAFM appliance.

As an alternative, you ca n perform the ﬁrmware upgrade directly to the director or edge

switch using their EWS.

Please contact your local HP technical resource if you ne ed to obtain a new HAFM

version.

Please contact your local HP technical resource to conﬁrm compatibility with devices

in your SAN before upgrading to this ﬁrmware version.

For more information on upgrading soft ware versions, refer to the HP StorageWorks

HA-Fabric Manager User Guide. The features of this software version are detailed in the

accompanying manuals listed in section Other edge switch documentation.

Zone FlexPar feature

Because zoni

ng is managed on a fabric-wide basis, a ll switches and directors in the

fabric must

maintain the same zoning conﬁguration. This conﬁguration is m aintained

automatically through the Fibre Channel protocol.

To keep this information current, RSCN messages are sent through the fabric to inform

attached devices when zoning changes occur, when devices become available, or

when devic

es become unavailable. In the case where devices become available or

unavailable, RSCNs are sent only to the devices in the same zone. Zoning changes,

however, trigger RSCNs to be sent to all of the devices in the fabric. As fabrics grow

larger and larger, the quantit y of RSCNs from zoning changes can create congestion

and disrupt devices, causing them to pause normal activity to determine the status of

the other devices. This can occur even if the new device is not zoned to talk to the

other devices in the fabric.

With th

e Zone FlexPar feature enabled, RSCN m essages for a zoning change are

handle

d like RSCNs for availability/unavailability changes. Speciﬁcally, RSCNs are

restricted to only those devices sharing at least one common zone with the device that

changed. This way, only devices that are impacted by the change in connectivity

recei

ve RSCNs.
