7Fabric OS 3.1.3a Release Notes
Important Notes
This section provides information you should be aware of when running
Fabric OS 3.1.3a.
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:

Mixed Fabric Environment with Different Switch Platforms
Fabric OS v2.6.2, v3.1.2, and v4.2.x introduced a new switch PID format:
Extended Edge PID (Format 2). Extended Edge PID is useful if you introduce a
Fabric OS 3.1.3a switch into a fabric consisting solely of Fabric OS v2.x/v3.x
switches. Before adding a Fabric OS v3.1.3a switch to such a fabric, refer to the
HP StorageWorks Fabric OS Procedures 3.1.x/4.1.x User Guide for information
on the Extended Edge PID format.
Note: Switches must operate with Fabric OS v2.6.2, v3.1.2, v4.2.x or later to use the
Extended Edge PID format.
If Extended Edge PID is set (before a downgrade from the current Fabric OS
release to an earlier Fabric OS release that does not support the Extended PID
format), PID needs to be set back to a supported format, such as Core PID
(format 1) or native PID (format 0).
Advanced Web Tool Updates
When using a mixed fabric—that is, a fabric that contains v4.x, v3.x, and v2.x
switches—HP recommends that you use the most advanced switches to control
the fabric. For example, use the 4.x switches as the primary Fibre Channel Switch
(FCS), as the location to perform zoning tasks, and as the time server. HP also
recommends that you use the most recently released firmware to control the
fabric.
If you use Advanced Web Tools to change the switch name, the HP StorageWorks
SAN Director 2/128 Telnet console prompt does not update to the new name until
a new Telnet window is opened.
