HP StorageWorks Director and Edge Switch release notes Part number: AA-RW8NB-TE/958–000276–010 Second edition: (September 2006)
Description These release notes contain late-breaking and supplemental information for the Edge Switch and Director products. These release notes are intended for customers who purchased Director or Edge Switch products. Read these release notes before installing a Director or Edge Switch product. This information is available and periodically updated on the web site http://h18006.www1.hp.com/storage/saninfrastructure/index.html.
Table 1 lists the supported switches, including the McDATA switch name and the corresponding HP switch name (if applicable).
Consider the impact of the following limits when planning the fabric: • Fabric elements—Each fabric element is defined by a unique domain ID that ranges between 1 and 31; therefore, the theoretical limit of interconnected Directors in a single fabric is 31. The supported limit of interconnected switches in a single fabric is 24. Because this number is subject to change, contact your HP-authorized service representative for the current number of interconnected switches supported in a single fabric.
Fixes Table 2 lists issues that have been fixed in this release. Table 2 Fixes in this release Description Affected models After upgrading an Edge Switch 2/32, yellow triangles are shown on HAFM for all ports that are inactive but have optics in them. Edge Switch 2/32 (Sphereon 3232) Trace route port IDs have incorrect fill byte. Zero fill byte should be LSB not MSB according to GS-5 and SW-4 Firmware family Event 507 occurs after hot insert of multiple UPM cards.
Description Affected models CTP fails with 411 01 53 22 continuously until unit was IML’ed. Director 2/64 (Intrepid 6040 Director) Fault 01A029 occurs. Director 2/64 (Intrepid 6040 Director) Flow assigned internally to a backend port on a QPM is rerouted to newly configured preferred exit port without waiting for rerouting delay. This has potential to cause out-of-order frames and the impact/recovery is dependent on the end node.
Compatibility and interoperability This section describes Edge Switch and Director product compatibility. HAFM and firmware compatibility Table 3 lists the minimum version of HAFM that can run with the various versions of firmware for the Edge Switches and Directors. Table 3 HAFM and firmware compatibility Firmware version HAFM version 01.01.02 04.00.01 (HP EFCM) 01.02.02-06 04.01.02-14 (SDCM) 01.03.00-35 04.02.00-40 (HP EFCM) 01.04.00-01 04.02.00-40 (SDCM) 02.00.00-33 06.00.00-45 (HP EFCM) 02.
Standards compliance Table 4 lists Fibre Channel standards compliance for firmware 09.00.00. Table 4 Standards compliance Category Specifics Fibre Channel protocols FC-GS-3 FC-GS-4 FC-PH Rev 4.
Firmware installation This section includes firmware installation information. Prerequisites for installing and using firmware 09.00.00 Consider the following prerequisites for firmware 09.00.00: • If you are using HAFM, firmware 09.00.00 requires HAFM 07.01.00 or later. This minimum version lets you manage Edge Switches and Directors running 09.00.00 firmware. However, to use all the new features and enhancements for firmware version 05.xx.xx and later, upgrade HAFM to 08.09.
• If upgrading firmware requires an upgrade from 04.xx.xx to 05.xx.xx in the process, there are special considerations, as described in, "Upgrading firmware on a Director from 04.xx.xx to 05.xx.xx" on page 11. • If upgrading firmware requires an upgrade from 06.xx.xx in the process, upgrade from 06.xx.xx to 07.01.03. Firmware 07.01.03 includes a fix to an issue that can occur when firmware is upgraded from 06.xx.xx to 07.xx.xx under very specific conditions. Other versions of 07.xx.
4. Using the Product Manager, execute a CTP swap: a. From the Product/Element Manager Hardware view, verify that an amber LED indicator is not displayed for either CTP card. b. Right-click the CTP card you believe to be active, and then select FRU Properties. Verify that it is the active CTP card. c. Right-click the active CTP card and select Switchover. The Director loses its Ethernet connection for a short time during the switchover process.
• When downgrading to a release earlier than 07.00.00, any modifications to the port RX BB_Credit settings using the new enhanced port configuration capability must be changed back to a configuration supported by older firmware. This enables the configuration to comply with the previous release’s configuration database. Firmware 07.xx.xx services verify compatibility and prevent downloads until the configuration conflict is resolved. • Downgrading directly to a release prior to 08.xx.xx from 09.00.
• If you are using the 1U rack-mount HAFM Appliance to manage the Director or Edge Switch, the minimum HAFM version required is 07.02.00-9, which is the minimum version installed. This HAFM software is contained on the HP StorageWorks ha-fabric manager documentation and software CD (Part Number 516-000024-720). • The previous minimum versions of HAFM allow you to manage Directors or Edge Switches running 09.00.00 firmware. However, to use all the new features and enhancements, upgrade HAFM to 08.09.
Zoning limits Table 5 lists the supported zoning limits for the Edge Switches and Directors.
Support for speed Auto-Negotiate Auto-negotiate is supported. However, HP recommends that the port speed for E_Ports (for Interswitch links, or ISLs) be set to a specific port speed (1Gb/sec, 2Gb/sec, or 4GB/sec as appropriate for the speed of the Directors or Edge Switches being connected) instead of to Negotiate. Using a specific port speed decreases the time for a fabric build in response to some perturbation event in the fabric.
Using HAFM Basic To determine the current version using HAFM Basic (firmware 08.xx.xx or later): 1. Using the IP address of the switch, log in to the Edge Switch or Director through a web browser. The Fabric View appears. 2. Click Details for the Edge Switch or Director. The Product > Hardware view appears. The firmware version appears in this view. Using Embedded Web Server To determine the current version using the Embedded Web Server (firmware 07.xx.xx or earlier): 1.
