Important notes
This section provides information you should be aware of when running Fabric OS 4.4.x.
OS requirements
HP recommends using the latest software release versions to get the greatest benefit from the SAN.
Refer to the following web site for information:

Maximizing fabric availability during HP StorageWorks
SAN Switch 2/32 hot code activation
During code activation on a HP StorageWorks SAN Switch 2/32 running Fabric OS 4.1.0 or later,
data keeps flowing between hosts and storage devices. However, fabric services are unavailable
for a period of approximately 50 to 55 seconds. Possible disruption of the fabric can be minimized
by ensuring that switches logically adjacent to the SAN Switch 2/32 (directly connected via an ISL)
are running, at the minimum, Fabric OS v2.6.1 or later, v3.1.0 or later, or v4.1.0 or later. More
information is available in the firmware download section of the
HP StorageWorks Fabric OS
