Important Notes 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 v4.2.x switch into a fabric consisting solely of Fabric OS v2.x/v3.x switches. Before adding a Fabric OS v4.2.x switch to such a fabric, refer to the HP StorageWorks Fabric OS 4.2.x Procedures User Guide for information on the Extended Edge PID format. Note: Note that in order to use the Extended Edge PID format, Fabric OS v2.6.2, v3.1.2, and v4.2.x must be deployed together, as applicable, to the switches. 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 v4.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. If a dialog box is displayed from the Switch Admin window of Advanced Web Tools and the user selects another dialog box from Advanced Web Tools, a window display error occurs. Workaround: HP recommends JavaTM 1.4.1_03. Two-Domain and Four-Domain Fabric Licensing If your fabric includes a switch with a license for a limited number of switches in the fabric and the fabric exceeds the limit, Advanced Web Tools allows a 45-day grace period during which you can still monitor the switch. Advanced Web Tools periodically displays warning messages. SAN Director 2/128 Fabric OS 4.2.x Release Notes 7

SAN Director 2/128 Fabric OS 4.2.x Release Notes
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 v4.2.x switch into a fabric consisting solely of Fabric OS v2.x/v3.x
switches. Before adding a Fabric OS v4.2.x switch to such a fabric, refer to the
HP StorageWorks Fabric OS 4.2.x Procedures User Guide
for information on the
Extended Edge PID format.
Note:
Note that in order to use the Extended Edge PID format, Fabric OS v2.6.2,
v3.1.2, and v4.2.x must be deployed together, as applicable, to the switches.
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 v4.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.
If a dialog box is displayed from the Switch Admin window of Advanced Web
Tools and the user selects another dialog box from Advanced Web Tools, a
window display error occurs.
Workaround:
HP recommends Java
TM
1.4.1_03.
Two-Domain and Four-Domain Fabric Licensing
If your fabric includes a switch with a license for a limited number of switches in
the fabric and the fabric exceeds the limit, Advanced Web Tools allows a 45-day
grace period during which you can still monitor the switch. Advanced Web Tools
periodically displays warning messages.
