Important Notes

This section provides information you should be aware of when running Fabric

OS 4.2.x.

OS Requirements

HP recommends using the latest software release versions to get the greatest

benefit from the SAN.

Important Notes

7SAN 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 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.

Important Notes

8 SAN Director 2/128 Fabric OS 4.2.x Release Notes

These messages warn you that your fabric size exceeds the supported switch

configuration limit and tells you how long you have before Advanced Web Tools

will be disabled. After the 45-day grace period, you will no longer be able to

launch Advanced Web Tools from the switch if it still exceeds the limit.

Note: Two domain and our domain fabric licensing is applicable only to 2 Gb/sec

switches.

Browser Window Response After Failover

A browser window might stop responding after an HA failover immediately after

a zoning configuration is enabled or disabled. It is likely that the web daemon was

terminated by the HA failover before the HTTP request was returned.

Workaround: If the HA module does not respond, close the window and

relaunch the module. If the module is locked, shut down and relaunch the Web

Tools application.

Switch View Display Issue

If you frequently enable or disable a switch or perform a power cycle, the Switch

View may not display properly. Launching other Web Tools components might

then cause a browser crash.

Workaround: Upgrade your Java Plug-in to 1.4.1_06 or later, if you are

running Windows XP.

Installing Mozilla 1.4 on Solaris 8 and Solaris 9

For instructions to install Mozilla 1.4 on Solaris 8 and Solaris 9, go to the web

site:

http://ftp.mozilla.org/pub/mozilla.org/mozilla/releases/mozilla1.4/mozilla-sparc-sun

-solaris2.8_1.4.readme

Mozilla Browser Support for Switch Admin Module

The Mozilla browser does not support the Switch Admin module properly in

Fabric OS v2.6.x. In Fabric OS v2.6.2, a warning message is displayed. No

warning message is displayed in other 2.6.x versions.

Workaround: Use Netscape 4.7.7 or later.
