Overview These release notes are intended for customers who purchased the 8/20q Fibre Channel Switch. The notes contain late-breaking and supplemental information for this product. It is important that you read these notes before installing your 8/20q Fibre Channel Switch. Because this information is updated periodically, HP recommends that you check the following HP website for the latest information: http://www.hp.com/go/8Gb-SSC.
Considerations for downgrading the firmware version Consider the following before downgrading firmware: • Downgrading the firmware to a previous version is a disruptive operation, so prepare attached devices for this disruption during the downgrade operation. • Before downgrading from firmware 8.0.2.02.00, change any ports configured as TR to GL using QuickTools or the CLI.
• One HP StorageWorks 8/20q Fibre Channel Switch (8 ports active) • One HP StorageWorks Fibre Channel Rack-Mount Kit • Four rubber mounting feet for the HP StorageWorks 8/20q Fibre Channel Switch (for desktop placement, if you are not using the rack-mount kit) •...
• Red Hat Enterprise Linux (RHEL) 4.5, 4.6, 5, 5.1, and 5.2 • SUSE Linux Enterprise Server (SLES) 9, SP3 and SP4; 10, SP1 and SP2 • HP-UX 11.23, 11.31 At this time, HP-UX is not supported with firmware 8.0.2.02.00. Support is expected in March 2009. For more details and the most recent information on supported operating systems, see the HP StorageWorks SAN Design reference guide located on the HP website: http://www.hp.com/go/...
or selecting the parent window while a child window was still open. If this occurred (a child window got behind a parent window) the parent appeared nonresponsive until the child window was closed. • Selective restore of Network Properties restored only Syslog information. •...
• Optical transceivers. Only the HP 8Gb Short Wave FC SFP+ (part number AJ718A) is supported for use in the HP StorageWorks 8/20q Fibre Channel Switch. This transceiver does not support 1 Gb/s port speed. If the port speed is configured as 1 Gb/s, the port is disabled and its state will be changed to Downed.
• The sum of the logged in devices plus the devices zoned with devices on that port is 64 or less. If these conditions are not satisfied, that switch port reverts to software enforced zoning (soft zoning). If the active zoneset is deactivated, where the fabric has more than 64 devices and default zoning is configured to ALLOW, the default zone created when the zoneset is deactivated will have more than 64 members.
Workaround: In QuickTools, select Fabric > Rediscover Fabric to refresh the PortWWN field in- formation. • Issue: When the maximum SMI-S connections are configured, the SMI-S listener may timeout and E_Ports may be taken offline and then back online. Workaround: Do not configure more than four SMI-S listeners. •...
Workaround: To update the IP address in SNMP, execute a switch reset. Note that this is a dis- ruptive action and should be planned for accordingly. • Issue: When upgrading firmware while in maintenance mode, the message "gpg: WARNING: This key is not certified with a trusted signature ..." is displayed. Workaround: This message is incorrect and may be ignored.
Using QuickTools To determine the current version of firmware using QuickTools: Log in to the 8/20q Fibre Channel Switch through a web browser using the switch IP address. Click the switch in the fabric tree displayed in the left panel. Select the Switch tab at the bottom of the faceplate display.
