hp StorageWorks SAN Switch Software v3.0.2k CD
10 SAN Switch 2/8 Version 3.0.2k Release Notes
hp StorageWorks SAN Switch Software v3.0.2k CD
The hp SAN Switch 2/8 ships with the latest version of the firmware installed. A
copy of the latest version of the firmware as of this date, v3.0.2k, is also contained
on the hp StorageWorks SAN Switch Software v3.0.2k CD, part number
AG-RR86C-BE. The v3.0.2k firmware is also available on the HP website at:
http://www.compaq.com/products/storageworks/hubs-and-bridges/firmwareupdate.html
v3.0.2k Firmware Overview
Firmware v3.0.2k works with HP StorageWorks 2 Gb switch models only. The
firmware will not work if loaded onto HP StorageWorks 1 Gb switch models.
Additionally, firmware release v3.0.2k provides fixes for problems associated
with v3.0.2j.
Firmware v3.0.2k Updates
Enhancements to firmware V3.0.2k include:
■3.0.2k provides support for the hp StorageWorks MSA SAN switch 2/8.
■Fan errors no longer display after a specific interval (414 days) of run time.
■Extends name service query time to 1 second from 0.12 second.
■No longer sends PDISK to a single Arbitrated Loop Physical Address (ALPA)
on a single port on the switch.
■Supports both Microsoft Internet Explorer and Netscape Navigator Browsers.
■Commands are insensitive to letter case. For example, the command line
accepts fabricshow as well as fabricShow.
■Active Zone Configuration Warning: Web Tools now issues a warning before
disabling an active zone configuration. This lowers the risk that a Zoned
Fabric may become un-zoned. A "Confirm Zone Delete" window appears
confirming deletion of a zone. The window also notifies the user that the
specified zone member will be removed from corresponding configurations.
The user should click Yes to continue, and No to cancel the zone delete.

Hardware Updates
11SAN Switch 2/8 Version 3.0.2k Release Notes
Excessive Error Counts
Encoding Out Error counts vary under the following conditions:
■When the switch port is set to auto-negotiation, and an N-port device is
connected, the port synchronization takes longer to complete, and a larger
error count displays.
■If a 1Gbps signal is received and the speed negotiation is transmitting at
2 Gbps, a larger error count displays.If the portSpeed and N-port device are
configured to 2 Gbps, encoding out errors are minimal. Similarly, if the
portSpeed and N-port device are configured to 1 Gbps, encoding out errors are
minimal.
■If auto-negotiation is set, the potential error count can be excessive.
Hardware Updates
The following sections list SAN Switch 2/8 hardware updates.
Verify Licenses Before Replacing Hardware
Prior to replacing a switch or motherboard, display and record the current feature
licenses active in the unit. Additional licenses could have been added to the switch
after the installation. Licenses that are active can be viewed from a Telnet session
using the licenseshow command, or they can be viewed from the Web Tools
GUI.
Cables
Optical cables for the Fibre Channel SAN Switches must be ordered separately.
Cables that are 500 meters or less for 1 Gbps and 300 meters or less for 2 Gbps,
should be multi-mode Fibre Channel cables. Cables that are longer than 500
meters should be single-mode.
Multi-mode optical cables are connected to short-wave Small Form Factor
Pluggable (SFP) modules in Fibre Channel SAN Switches. Single-mode optical
cables are connected to longwave SFP modules in the Fibre Channel SAN
Switches. Multi-mode cables should use 50/125 optical fibers, SC Duplex
connectors with a PC finish.
Use of 62.5/125 should be restricted to situations where 62.5/125 optical fiber was
previously installed and the link lengths are to be kept shorter than 200 meters at 1
Gbps and shorter than 150 meters for 2 Gbps.

Compatibility
12 SAN Switch 2/8 Version 3.0.2k Release Notes
Compatibility
SAN Switch firmware v3.0.2k is compatible with the StorageWorks SAN Switch
software version 2.6.0h, allowing both 1 and 2 Gb switches to operate in the same
fabric.
For the latest supported configurations, please refer to the hp StorageWorks SAN
Design Reference Guide, part number AA-RMPNF-TE, available at:
http://www.compaq.com/products/storageworks/san/documentation.html
Note: hp StorageWorks 1 Gb switch models running software version 1.6d are not
supported with the SAN Switch 2/8.
The minimum supported firmware level for the StorageWorks Enterprise Virtual
Array is VCS v1.02. The upgrade of the Enterprise storage subsystem firmware
must be performed before the upgrade of the switch firmware. Please consult the
Enterprise Virtual Array technical documentation for specific information for
upgrading VCS firmware.
Important Information about the IV_Domain_Fabric License
Read the following sections for important information regarding the
IV_Domain_Fabric license installed on your SAN Switch 2/8 EL model only.
Four Switch Limitation
The SAN Switch 2/8 EL shipping configuration integrates the IV_Domain_Fabric
license. The IV_Domain_Fabric license limits the number of switches that can be
connected to a single fabric to four. If more than four switches (of any type) are
added to the fabric where EL switches are installed, Web Tools generates multiple
error messages.
Note: You can upgrade the 2/8 EL switch to full fabric support by installing an
optional upgrade license. See the “Four Switch Limitation Workarounds” described in
these Release Notes for instructions on how to purchase the Full Fabric license.

Management Station Requirements for Running Web Tools
13SAN Switch 2/8 Version 3.0.2k Release Notes
Four Switch Limitation Workarounds
Use one of the following workarounds to prevent four switch limitation errors.
■Upgrade the current HP StorageWorks SAN Switch 2/8 EL
IV_Domain_Fabric license to the optional Full Fabric license. The Full Fabric
license provides full fabric functionality, with no limits on the number of
switches in the fabric.
For purchasing information, contact your authorized HP Sales representative,
or go to the HP storage website at:
http://www.hp.com/country/us/eng/prodserv/storage.html
Note: Complete installation instructions are provided with each license. After the Full
Fabric license is installed, the fabric identifies the switch as a 2/8-EL with a Full Fabric
license, providing full fabric functionality.
■In fabrics which contain five or more switches, with at least one switch with
the IV_FABRIC license installed, reduce the number of switches to four or
less.
Management Station Requirements for Running Web Tools
