OS Requirements HP recommends using the latest software release version to get the greatest benefit from the SAN.
Important Notes 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 recently released switches to control the fabric. For example, use the v4.
Important Notes 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: If you are running Windows XP, upgrade your Java Plug-in to 1.4.1_06 or later. Installing Mozilla 1.4 on Solaris 8 and Solaris9 For instructions to install Mozilla 1.4 on Solaris 8 and Solaris 9, go to: http://ftp.mozilla.org/pub/mozilla.org/mozilla/releases/mozilla1.

Important Notes Table 4: Fabric OS Area Information (Continued) Fabric OS Area Description Fabric Device Management Interface (FDMI) An HBA will be allowed to register even though the originating port is not on the HBA's registered port list. This is intended behavior, included to test error cases. Fabric OS: CLI commands, failover, and port disable Changing port configurations during a failover might cause ports to be disabled.
Important Notes Table 4: Fabric OS Area Information (Continued) Fabric OS Area LTO 2 tape drive support Description When using the LTO 2 tape drive, the user must enter the following command on both Fabric OS v3.x and v4.x: switch> portcfggport port# where drive is plugged in This allows the tape drive to function in point-to-point mode rather than in loop mode. rsh and rlogin The programs rsh and rlogin are not supported in this release.
Important Notes Table 4: Fabric OS Area Information (Continued) Fabric OS Area Description Security: PKICERT utility, installing certificates PKICERT v1.0.6 is the most current version of the PKICERT utility. When running the PKICERT utility to install switch certificates in a fabric that did not previously contain switch certificates, select the option to specify that certificates are installed on only those switches that do not currently contain certificates.
Commands Modified in v4.2.x Table 4: Fabric OS Area Information (Continued) Fabric OS Area Description Zoning: license To use Zoning in a non-RCS (reliable commit service) mode fabric (that is, in a fabric containing switches with firmware versions other than v2.6.x, v3.1, and v4.1), HP recommends that all appropriate Zoning licenses be installed on all the switches in the fabric before attempting to bring a switch in to the fabric.

Documentation Updates portCfgislMode Add a Note regarding coexistence with the portCfgLongDistance command, as follows: Note: portCfgislMode and portCfgLongDistance cannot both be enabled at the same time; otherwise, fabric segmentation occurs HP StorageWorks Fabric OS 4.2.x Procedures User Guide On page 59, add the following note after the paragraph: Domain IDs are assigned dynamically when a switch is enabled.
Issues and Workarounds Issues and Workarounds Table 5 lists current issues that customers should be aware of and provides workarounds. Table 5: Issues and Workarounds Issue Workaround The message Oops: kernel access of bad area, sig: 11 is displayed and the switch is reset. The problem was caused by an error in the test script, in which the Zoning cfg command was issued to the Standby CP by accident. Downloading configurations by line too quickly on v4.2.x switches causes the switch to panic and crash.
Issues and Workarounds Table 5: Issues and Workarounds Issue SwitchCfgTrunk leaves ports disabled, if a long distance port is configured on the switch. Workaround There are two ways to avoid this issue: ■ (Recommended) Use the command port port cfg trunk port to enable the trunk for each port. ■ Disable the long distance ports before issuing switchcfgtrunk. Immediately after activating SCC policy, the retrieve sec policy through API fails.
