QLogic 3810, QLogic 5000 Series, and QLogic 5800V Series Switch Firmware Version 7.4.0.29.00 50949-16 Rev A QLogic Corporation All rights reserved Table of Contents 1 Overview 2 Installing the Firmware Using Telnet 3 Interoperability 4 Documentation 5 Additional Information 6 Contacting Support 1 Overview The QLogic 3810 switch can be managed with the Command Line Interface (CLI) or with the QuickTools graphical user interface. It cannot be managed with Enterprise Fabric Suite (EFS). A hot reset (Non-Disruptive Code Load Activation or NDCLA) is not supported when downgrading firmware versions. A switch reset must be performed. Firmware 7.4 introduces IPv6. Changes made to support IPv6 require a switch reset for QLogic 5000 Series customers running firmware version 6.8 and earlier. Therefore, an NDCLA is not available for these customers. The maximum number of devices tested with this release are defined as follows: Maximum of 32 devices per port Maximum of 640 devices connected to the switch (any E-ports count as one device each) Maximum of 2,048 devices in the fabric The maximum number of hops (ISL links) tested per fabric is seven. You are allowed one active EFS or API session while executing an NDCLA when you have a fabric with switches with pre-6.x firmware. If all the switches in the fabric are at 6.x or later, then multiple EFS and/or API sessions are allowed. For the QLogic 5000 Series switches, the default setting for DefaultZone is ALLOW for ease of use by customers with small fabrics. For QLogic 9000 Series switches, the default setting for DefaultZone is DENY. The change was implemented for QLogic 9000 Series switches with firmware versions 6.2.1.03 and later. In fabrics with both 5000 Switch Firmware Version 7.4.0.29 Read Me Page 1 of 7
Series and 9000 Series switches, the best practice is, for security reasons, to set DefaultZone to DENY for all switches. When deactivating and reactivating a zone set, if a fabric has more than 64 devices and DefaultZone is set to ALLOW, devices may revert to being soft zoned and stay soft zoned after the zone set activation. A log message will be generated for the ports to which these devices are attached. A reset of the ports will be needed after zoning has been reactivated, if the user wishes the devices to be hard zoned. To hard zone the devices, the corresponding ports must be reset after the zone set is reactivated. If you are downgrading from firmware version 6.7 or later to version 5.0.1 or earlier on a QLogic 5000 Series switch with DefaultZone set to ALLOW and an active zone set, devices in different zones will see each other regardless of the DefaultZone setting. To maintain the correct firmware 5.0.1 behavior, you should set the DefaultZone parameter to FALSE before downgrading to firmware 5.0.1 or earlier. The Set Port State and Set Switch State CLI commands make temporary changes to the port and switch states respectively, and are not persistent across port and switch resets. Furthermore, changes you make to the switch configuration using Enterprise Fabric Suite and QuickTools will override these temporary changes. When a host connected to a port on a QLogic 5000/9000 Series switch sends an LINIT or LSTS ELS frame to a remote domain address, the requested initialization of the storage port occurs though the response from the storage port is blocked by the switch. Storage devices support a device-dependent number of host logins (PLOGIs). For each PLOGI that the storage device receives that exceeds this limit, the storage device sends an LS_RJT to the requesting host. If a host cannot successfully log in to a storage device due to this limit, the host may log out of the fabric (or drop the link), and retry the process. If this is happening in your fabric, you may observe a rising number of link failures (see the show port < port number>) and repeated alarms similar to the following: Alarm Msg: [Fri Jan 27 16:27:08.172 CST 2006][A][1004.0050 [Port: 3][Maximum hard zoning member limit exceeded, Reverting to soft zoning. Requires port reset.] This issue has been observed only in fabrics with large numbers (hundreds) of storage devices and hosts sharing a single zone. Large inactive zone sets may cause the switch to exceed its zoning database limits when activating or deactivating a zone set. You may see the error message Activation failed, SFC failure received from remote switch. To avoid this issue, the best practice is to manage the fabric from a single switch and to set the DiscardInactive attribute to True for the other switches in the fabric. A fabric that crosses time zones will produce time stamp differences in the different switch logs. If you are not using NTP to manage the date/time and manually change the date/time, and then change the time zone, the subsequent date/time will be incorrect. To avoid this issue, change the time zone first, and then the date/time. If you are not using NTP on a QLogic 5000 Series switch to manage the date/time and you downgrade the firmware to a version earlier than 6.7, the date/time will be incorrect because of a difference in the way time is stored in the firmware. You must manually reset the date/time. A switch configuration backup does not archive the primary or secondary secrets for any security groups. Therefore, after restoring the configuration, you must redefine the security secrets using the CLI. Otherwise, the restored switch will isolate from the fabric due to the missing secrets. When enabling SSH on a switch for the first time, the login session may become unresponsive for a short time while the SSH key is being generated. This is a one-time occurrence; the amount of time depends on the switch CPU workload. After the key generation completes, the switch resumes normal operation.

The CLI displays 64-bit port counters. By MIB definition, SNMP port counters are allowed to display only 32-bit counters. The SNMP port counters do not match the CLI port counters when the values exceed 32-bits. For Picolight Model #PL-XPL-VC-SG3-22 SFPs, the Tx Bias and Tx Pwr parameters will intermittently show values of 0.00 when the show media command is executed. The LowAlarm status on Tx Bias, Tx Pwr, and RxPower may also be displayed. The 0.00 values and alarms can be ignored when this occurs. This applies only if the switch has a SANdoctor license. For Agilent Model #AFBR-57R5AP SFPs, the Tx Bias parameter will go to LowAlarm status on show media commands that follow multiple show media n commands during port autospeed negotiation. This can also occur after moving ports between offline and online status. The LowAlarm status and any 0.00 values can be ignored in this situation. This applies only if the switch has a SANdoctor license. For some Seagate storage, the fcping command reports failed if the storage is attached to a remote switch. The command will work if the storage is attached to the local switch. This applies only if the switch has a SANdoctor license. When attaching an 8G Emulex adapter (LP 1200x) to a port on the QLogic 5800V/5802V switch to run at 8Gbps, the switch port speed must be set to 8G instead of the default of Auto, and the switch port type must be set to G_Port instead of the default of GL_Port. If the port speed and port type are not set as specified, the port may fail to come online. 8Gb SFPs do not support 1Gb speed. The port will be downed if an 8Gb SFP is inserted and the port speed is set to 1Gb. The embedded application for basic discovery, setup, configuration, and zoning management is QuickTools. While running QuickTools, if you change the IP address of the switch where QuickTools resides, the QuickTools session (at the old IP address) will stop responding. To work around this issue, specify the new IP address in a new browser window. When running QuickTools, Java plug-in caching should be disabled. If caching is enabled and you load a different version of QuickTools from a switch onto your client, the previously running version of QuickTools will load from the cache, even though the version number will be for the QuickTools loaded from the switch. Also, if you have Java plug-in caching disabled and you upgrade your Java version, caching may become enabled and will have to be disabled again. If Java support is disabled in the browser, or if scripting support is disabled in the browser, QuickTools will not launch. The scripting support is referred to as "Enable JavaScript" in most browsers, and as "Active scripting" or "Active Web Content" in Internet Explorer. When navigating within QuickTools, use the buttons within the application instead of the browser buttons to insure proper operation. When running QuickTools with Windows Internet Explorer, if you select a file that specifies Windows Internet Explorer as the default browser to use for that file type, when the page is brought up in the same Windows Internet Explorer browser window, QuickTools is automatically closed. You can work around this issue by opening a second Internet Explorer browser window after loading QuickTools in the first Internet Explorer browser window. Files that specify the use of Internet Explorer will open in the second window. If you disable QuickTools through the System Services dialog box while in a QuickTools session, you will still be able to manage the switch during the current browser session. You must close the current browser to apply the change. For QLogic switches with an IPv6 address, to run QuickTools on Windows Internet Explorer, you must use Internet Explorer 7.0 or later. To access the QuickTools online help on a browser other than Windows Internet Explorer, you must specify the directory location for your browser in the Preferences dialog box.

InteropMode set to Standard (FC-SW-2) supports Brocade, McDATA, and Cisco switches in their "interop" or "Open" modes: Brocade Silkworm 3200/3800; Firmware tested: v3.2.0 Brocade Silkworm 3900; Firmware tested: v5.30d Brocade Silkworm 3250, 200E, 4100; Firmware tested: v5.2.0b, v5.3.0d Brocade M4400, M4700, M6140; Firmware tested: 9.00.00 build 76, 9.01.00.50 Cisco MDS 9509, 9216, 9216i; Firmware tested: 3.0.2a, 3.1.2a, 3.2.(3) 3.1 Known Issues with Brocade/QLogic Operation that Are Not Documented in the Interoperability Guide: InteropMode of 1 (Interop_1) is no longer supported with firmware version 6.6 and later. Only InteropMode of 0 (Standard) is supported. Connecting a QLogic switch to a Brocade switch through G_Port will cause the Brocade switch to become inoperable. To work around this issue, change the QLogic port to a G_Port. The Brocade switch demonstrates this issue with non-qlogic switches also. With InteropMode set to Standard (FC-SW-2) and connected to a Brocade 3250 switch (4.2.0c firmware), Brocade BB credit negotiation does not work properly while traffic is running if the QLogic switch has fewer BB credits than the Brocade 3250 switch. To resolve this issue, reconfigure the BB credits on the Brocade switch to match those on the QLogic switch. With InteropMode set to Standard (FC-SW-2) and connected to a Brocade 3200/3800 switch (3.1.0 or later firmware) and a Brocade 3900 switch (4.1.0 firmware or later), if a cfgsave command is issued from the Brocade switch for a zone change with a full zone database, a non-standard value is included in the save command payload. The QLogic switch will reject the command, which causes the save to fail. A workaround is to issue a cfgenable command from the Brocade switch to activate and save the zone change. When in Standard mode in a fabric containing Brocade switches, the domain ID of the QLogic switch should be configured to a value in the range 0x61-0x7f. If the domain ID is not set to a value in this range, the interswitch link will fail. 3.2 Known Issues with McDATA/QLogic Operation that Are Not Documented in the Interoperability Guide: McDATA's EFCM Basic embedded application and CLI do not display devices attached to the QLogic switch. A workaround is to use the McDATA EFCM application, v7.0 or later. When in Standard mode in a fabric containing McDATA switches, the domain ID of the QLogic switch should be configured to a value in the range 0x61-0x7f. If the domain ID is not set to a value in this range, the interswitch link will fail. With a mixed fabric of QLogic and McDATA switches running in Standard mode, one the McDATA switches must be configured as the principal switch. If this is not done, you may see zoning, name server, and security issues. If there is a McDATA 6140 switch running firmware 09.00.00, build 76, anywhere in the fabric, the embedded CIM agent will return invalid port state, ProtocolEndpoint, and ActiveConnection information for remote switches in the fabric. To work around the issue, disable Management Server (OSMS) on the McDATA switch. This will discard port information on the McDATA switch, but other switches in the fabric will no longer be affected. When configuring fabric binding with a McDATA switch in the fabric, specify the binding domain ID to be the switch running domain ID minus 60hex. Switch Firmware Version 7.4.0.29 Read Me Page 5 of 7
3.3 Known Issues with Cisco/QLogic Operation that Are Not Documented in the Interoperability Guide: When using EFS to configure a security set with a Cisco switch in the fabric, the Cisco switch's base WWN does not appear in the drop-down menu of WWNs, and must be typed. The VSAN address structure does not share the Cisco switch base WWN. 4 Documentation Installation, setup and management of the QLogic 3800, 5000 and 5800V Series switches are described in the following guides: QLogic 3810 Quick Start Guide, 59267-01 Rev A QLogic 3810 Fibre Channel Switch Installation Guide, 59268-00 Rev C QLogic 3810 QuickTools Switch Management User Guide, 59269-00 Rev B QLogic 3810 Fibre Channel Switch Command Line Interface Guide, 59270-00 Rev B QLogic 5600 Series Quick Start Guide, 50328-12 Rev A QLogic 5600 Series Fibre Channel Switch Installation Guide, 59096-06 Rev B QLogic 5600 Series QuickTools Switch Management User Guide, 59235-03 Rev B QLogic 5600 Series Enterprise Fabric Suite User Guide, 59097-06 Rev B QLogic 5600 Series Fibre Channel Switch Command Line Interface Guide, 59183-03 Rev B QLogic 5800V Series Quick Start Guide, 50861-03 Rev A QLogic 5800V Series Stackable Fibre Channel Switch Installation Guide, 59265-02 Rev A QLogic 5800V Series QuickTools Switch Management User Guide, 59264-02 Rev B QLogic 5800V Series Enterprise Fabric Suite 2007 User Guide, 59266-01 Rev B QLogic 5800V Series Stackable Fibre Channel Switch Command Line Interface Guide, 59263-02 Rev B QLogic 3800/5800 Fibre Channel Switch Rack Mounting Guide, 59109-04 Rev.
