User manual HP COMPAQ FIBRE CHANNEL SWITCH FIBRE CHANNEL SAN SWITCH 16 RELEASE NOTES

[. . . ] The v2. 1. 7 firmware is also available on the Compaq website at www. compaq. com/products/storageworks/hubs-and-bridges/firmwareupdate. html This firmware is for the Fibre Channel SAN Switch only and will not work if loaded into older Fibre Channel Storage Switches. Compatibility The Fibre Channel SAN Switch software (version 2. 1. 7 and above) is compatible with the Fibre Channel Switch software (versions 1. 6d), allowing both types of switches to operate in the same fabric. To accomplish this compatibility, the Fibre Channel SAN Switch must be configured to use a specific addressing mode. This mode is designated "VC Encoded Address Mode. " Invoke this mode using the configure command, as described in Appendix A of TM the Compaq StorageWorks Fibre Channel SAN Switch Management Guide. When using compatibility mode, the maximum switch count in a fabric is reduced from 239 to 32, and the maximum number of multicast groups is reduced from 256 to 31. [. . . ] Install the Windows NT FTP server on your system from your Windows NT installation CD. If you only use the FTP server for the firmware and configuration loads, you can specify the folder created in Step 1 as the FTP Publish Directory. Open the Internet Service Manager Tool found in the Start menu under Internet Information Service or Peer Web Service. Clear "Allow Anonymous Connections" if the password-restricted access is desired. Select the Directories tab then select the folder you created in Step 1. If this folder was not selected as the root folder add it to the list. Highlight the folder and make sure the read and write boxes are selected. Close the Internet Service Manager Tool. Perform a configuration save by using the Telnet command configUpload. In the instructions, the source files that are referred to are the standard Windows NT server or Workstation CD. FTP Service uses the standard users defined under Windows NT, so a valid local user and password is required. A user can be created using the Windows NT administrative tools. Appropriate permissions for the created folder (NTFS volumes only) must be setup to allow the user to have read and write privileges. Another link that may be used to create a specific directory structure for use of firmware downloads explains how to create a directory structure for a specific login, but this is not necessary if FTP is only being used for switch use. 8 Compaq StorageWorks Fibre Channel SAN Switch 16 Release Notes Telnet Command qlPortShowAll The qlPortShowAll command displays the following QuickLoop port information for each port: QuickLoop Mode Enabled--QuickLoop mode enabled Disabled--QuickLoop mode disabled Looplet State Online--Completed loop initialization Lipped--NL_port lipped Lipping--FL_port lipped Initializing--Loop initialization in progress Bypassed--Looplet being bypassed Error--Error found in this looplet Offline--Looplet offline Fabric--OLD_PORT state Not in QuickLoop Mode--Port is not in QuickLoop mode ssn The Fibre Channel SAN Switch has a software readable serial number that can be accessed by using the Telnet command "ssn. " Switches that have been upgraded to firmware v2. 1. 7 will not display the software readable serial number when this command is given, instead the switch World Wide Name (WWN) will display. If you have a switch with firmware v2. 1. 7 preinstalled and the switch displays the WWN instead of the software readable serial number, contact customer service. Compaq StorageWorks Fibre Channel SAN Switch 16 Release Notes 9 Known Issues This section describes the known issues and problems related to the Fibre Channel SAN Switches, as of 6/1/00. Fibre Channel SAN Switch Only eight E-ports per switch are supported. QuickLoop QuickLoop, with large numbers of looplets (16), can cause some adapters to time out during initialization, resulting in repetitive initializations. A new Telnet command has been added that can speed up initialization: qlUnmaskLipa [ 0 | 1 ] The parameter can be set to "0" or "1". When set to "0", initializing a looplet is off. When set to "1" (the default for new switches), initializing a looplet is on. When the parameter is set to initializing a looplet, the v2. 1. 7 QuickLoop masks the Arbitrated Loop Physical Address (AL_PA) bits in the Loop Initialization Procedure (LIPA) frame using the LIPA bitmaps of those looplets that stay online. Setting this option on disables the LIPA bitmap masking and opens AL_PAs for taking by devices in the looplet being initialized in the LIPA phase, thus allowing the Primary to claim the same AL_PA in the case of fail-back in Compaq's HA environment. Firmware v2. 1. 7 provides a Telnet command called backSpace. backSpace without any parameters, returns the current state of the parameter. [. . . ] Two longwave GBIC modules and a short single-mode test cable can be ordered in a kit (part number 340412-B21). In the Switch Management Application page of the Web Management Tools, the GBICs are identified differently depending on the type of GBIC and the supplier. Some examples of the displays include "ID" for VIXEL shortwave GBICs and "SW" for IBM shortwave GBICs. NOTICE The information in this document is subject to change without notice.
