1 Gathering information for your switch support provider 1. Connect to the switch and log in using an account with admin permissions. 2. Enter the appropriate supportSave command based on your needs: • If you are saving to an FTP or SCP server, use the following syntax: supportSave [-n] [-c] When invoked without operands, this command goes into interactive mode. The following operands are optional: -n—Does not prompt for confirmation.
Building a case for your switch support provider 1 Capturing output from a console Some information, such as boot information is only outputted directly to the console. To capture this information, you must connect directly to the switch through its management interface, either a serial cable or an RJ-45 connector that is specifically used for Ethernet connection to the management network. 1. Connect directly to the switch using hyperterminal. 2.
1 Building a case for your switch support provider • Are there VE, VEX, or EX ports connected to the chassis? Yes or no. Use the switchShow command to determine the answer. • How large is the fabric? Use the nsAllShow command to determine the answer. • Do you have encryption blades or switches installed in the fabric? Yes or no. • Do you have Virtual Fabrics enabled in the fabric? Yes or no. Use the switchShow command to determine the answer.
Building a case for your switch support provider 1 • Are specific devices affected? - If so, what are their World Wide Number Names? • What happened prior to the problem? • Is the problem reproducible? - If so, what are the steps to reproduce the problem? • What configuration was in place when the problem occurred? • A description of the problem with the switch or the fault with the fabric.
1 Building a case for your switch support provider Gathering additional information The following features that require you to gather additional information. The additional information is necessary in order for your switch support provider to effectively and efficiently troubleshoot your issue. Refer to the chapter or document specified for the commands used for the data you must capture: • • • • • • 10 Configurations, refer to Chapter 3, “Connectivity”.

2 Frame Viewer Frame Viewer When a frame is unable to reach its destination due to timeout, unroutable, or destination unreachable, it is discarded. You can use Frame Viewer to find out the flows that contained the dropped frames, which can help you determine which applications might be impacted. Using Frame Viewer, you can see exactly what time the frames were dropped. (Timestamps are accurate to within one second.) Additionally, this assists in the debug process.
Switch message logs 2 However, in this limited example, the Track Change feature reports this event inaccurately to the system message log; it appears that the login was successful. This scenario only occurs when the maximum number of users has been reached; otherwise, the login information displayed in the system message log reflects reality. Refer to the Fabric OS Administrator’s Guide for information regarding enabling and disabling Track Changes (TC).
2 Switch boot Switch boot Symptom The enterprise-class platform model rebooted again after an initial bootup. Probable cause and recommended action This issue can occur during an enterprise-class platform bootup with two CPs. If any failure occurs on the active CP, before the standby CP is fully functional and has obtained HA sync, the standby CP may not be able to take on the active role to perform failover successfully. In this case, both CPs reboot to recover from the failure.
Switch boot 2 • Software Fault: Kernel Panic - If the system detects an internal fatal error from which it cannot safely recover, it outputs an error message to the console, dumps a stack trace for debugging, and then performs an automatic reboot. - After a kernel panic, the system may not have enough time to write the reboot reason, causing the reboot reason to be empty. This is treated as a reset case.
2 FC-FC routing connectivity 3. Enter the supportSave command to go into interactive mode. Alternatively, if using a USB device, enter usbstorage -e. 4. Respond to the prompts. 5. Once the supportSave command had completed, contact your service support provider to provide them with the data. The following message is an example of the screen on a Brocade DCX. Fabos Version 7.1.
FC-FC routing connectivity 2 On the edge Fabric OS switch, make sure that the source and destination devices are properly configured in the LSAN zone before entering the fcPing command. This command performs the following functions: • Checks the zoning configuration for the two ports specified. • Generates an ELS ECHO request to the source port specified and validates the response. • Generates an ELS ECHO request to the destination port specified and validates the response.
2 FC-FC routing connectivity Example using fcPing with a single destination (in this example, the destination is a device node WWN) switch:admin> fcping 20:00:00:00:c9:3f:7c:b8 Destination: 20:00:00:00:c9:3f:7c:b8 Pinging 20:00:00:00:c9:3f:7c:b8 [0x370501] with 12 bytes of data: received reply from 20:00:00:00:c9:3f:7c:b8: 12 bytes time:825 usec received reply from 20:00:00:00:c9:3f:7c:b8: 12 bytes time:713 usec received reply from 20:00:00:00:c9:3f:7c:b8: 12 bytes time:714 usec received reply from 20:00:
FC-FC routing connectivity FIGURE 1 2 Superping and fcPing paths In the following example, Superping is invoked using the fcPing --allpaths command to destination domain 165. The following example displays each hop in (Domain1/Index1-> Domain2/Index2) format. To reach destination domain 165 from source domain 3 there are two unique end-to-end paths. In the first path, the frame traverses from egress port index 205 on source domain 3 to ingress port index 25 on domain 207.
2 FC-FC routing connectivity Consider the following example in which a few errors are recorded on ISLs 3/205-->2/25, 3/204-->2/27, 2/42-->101/3, and 2/1-->101/8. The potential faulty link is internal port 0/284 on domain 2 with the maximum of 100 percent failure.
FC-FC routing connectivity 2 Routing and statistical information The pathInfo command displays routing and statistical information from a source port index on the local switch to a destination port index on another switch. This routing information describes the full path that a data stream travels between these ports, including all intermediate switches. ATTENTION Using the pathInfo command when exchange-based routing is turned on can provide different paths with each attempt.

3 Port initialization and FCP auto-discovery process • VEX_Port—A virtual EX_Port. It connects a Fibre Channel router to an edge fabric. From the point of view of a switch in an edge fabric, a VEX_Port appears as a normal VE_Port. It follows the same Fibre Channel protocol as other VE_Ports. However, the router terminates VEX_Ports rather than allowing different fabrics to merge as would happen on a switch with regular VE_Ports. Figure 2 shows the process behind port initialization.
Link issues 3 Link issues Symptom Port LEDs are flashing. Probable cause and recommended action Depending on the rate of the flash and the color of the port LED, this could mean several things. To determine what is happening on either your port status LED or power status LED, refer to that switch’s model hardware reference manual. There is a table that describes the purpose of the LEDs and explains the current behavior as well as suggested resolutions. Symptom Port LEDs are steady.
3 Connection problems Checking the logical connection 1. Enter the switchShow command. 2. Review the output from the command and determine if the device successfully logged in to the switch. • A device that is logically connected to the switch is registered as an F_Port, L_Port, E_Port, EX_Port, VE_Port, VEX_Port, or N_Port. • A device that is not logically connected to the switch is registered as a G_Port or U_Port, if NPIV is not on the switch. 3.
Connection problems 3 Checking the Name Server 1.
3 Link failures 4. Enter the fcpProbeShow command to display the FCP probing information for the devices attached to the specified F_Port or L_Port. This information includes the number of successful logins and SCSI INQUIRY commands sent over this port and a list of the attached devices. 5. Check the port log to determine whether or not the device sent the FLOGI frame to the switch, and the switch probed the device.
Link failures 3 Checking for a loop initialization failure 1. Verify the port is an L_Port. a. Enter the switchShow command. b. Check the last field of the output to verify that the switch port indicates an L_Port. If a loop device is connected to the switch, the switch port must be initialized as an L_Port. c. Check to ensure that the state is online; otherwise, check for link failures.
3 Marginal links 4. Skip over the loop initialization phase. After becoming an active port, the port becomes an F_Port or an E_Port depending on the device on the opposite side. If the opposite device is a host or target device, the port becomes an F_Port. If the opposite device is another switch, the port becomes an E_Port. If there is a problem with the host or target device, enter portCfgGPort to force the port to try to come up as point-to-point only.
Marginal links 3 Only one frame is transmitted and received at any given time. An external cable is not required to run this test. The port LEDs flicker green rapidly while the test is running. Table 5 shows the different loopback modes you can use when using portLoopbackTest to test a marginal link.

Device login issues 3 Device login issues A correct login is when the port type matches the device type that is plugged in. In the following example, it shows that the device connected to Port 1 is a fabric point-to-point device and it is correctly logged in an F_Port. switch:admin> switchshow switchName:brcd5300 switchType:64.
3 Device login issues 3. Enter the portCfgShow command to see if the port is configured correctly. In some cases, you may find that the port has been locked as an L_Port and the device attached is a fabric point-to-point device such as a host or switch. This would be an incorrect configuration for the device and therefore the device cannot log in to the switch. To correct this type of problem, remove the Lock L_Port configuration using the portCfgDefault command.
Media-related issues 3 6. Enter the portLogDumpPort portid command where the port ID is the port number; then, view the device-to-switch communication. switch:admin> portlogdumpport 8 | more time task event port cmd args ------------------------------------------------Thu Nov 6 16:52:39 2008 16:52:39.066 PORT scn 8 1 00010004,4302000f,02000000 16:52:39.066 PORT scn 8 2 ce3dfab0,d9672800,00000002 16:52:39.066 PORT scn 8 2 ce3dfab0,d9672800,00000080 16:52:39.
3 Media-related issues The following procedures are for checking switch-specific components. Testing the external transmit and receive path of a port 1. Connect to the switch and log in as admin. 2. Connect the port you want to test to any other switch port with the cable you want to test. 3. Enter the portLoopbackTest -lb_mode 2 command. Testing the internal components of a switch 1. Connect to the switch and log in as admin. 2.
Segmented fabrics 3 Segmented fabrics Fabric segmentation is generally caused by one of the following conditions: • Incompatible fabric parameters (refer to “Reconciling fabric parameters individually” on page 37) • • • • • • • Incompatible zoning configuration (refer to Chapter 9, “Zoning”) Domain ID conflict (refer to “Reconciling fabric parameters individually” on page 37) Fabric ID conflict (refer to Chapter 7, “Virtual Fabrics”) Incompatible security policies Incorrect fabric mode Incorrect policy
3 Segmented fabrics 8. Enter the configure command to edit the appropriate fabric parameters for the segmented switch. 9. Enable the switch by entering the switchEnable command. Alternatively, you can reconcile fabric parameters by entering the configUpload command for each switch and upload a known-good configuration file. If you do this option, the two switches must be the same model.
Segmented fabrics 3 Example of setting the domain ID switch_89:FID89:admin> switchdisable switch_89:FID89:admin> configure Configure...

3 Port mirroring Port mirroring With port mirroring, you can configure a switch port to mirror the traffic between a specific source and destination port. This is only supported between F_Ports. This is a useful way to troubleshoot a problem port without bringing down the host and destination links to insert an inline analyzer. Port mirroring captures traffic between two devices. It mirrors only the frames containing the SID/DID to the mirror port.
Port mirroring 3 • Deleting a port mirroring connection with IOD enabled causes frame drop between two endpoints. • Using the firmware download procedure to downgrade to previous Fabric OS releases that do not support port mirroring requires that you remove all the port mirroring connections. If you downgrade to a previous version of Fabric OS, you cannot proceed until the mirroring connections are removed.

4 Configuration upload and download issues • The FTP or SCP server’s IP address cannot be contacted. Verify that you can connect to the FTP server. Use your local PC to connect to the FTP server or ping the FTP server. Example of a successful ping C:\> ping 192.168.163.50 Pinging 192.168.163.50 with 32 bytes of data: Reply from 192.168.163.50: bytes=32 time=5ms TTL=61 Ping statistics for 192.168.163.
Configuration upload and download issues 4 • On a Virtual Fabrics-enabled switch, you do not have the chassis role permission set on your user account. Implement one change at a time, then issue the command again. By implementing one change at a time, you are able to determine what works and what does not work. Knowing which change corrected the problems help you to avoid this problem in future endeavors. Symptom The configuration download fails.
4 Brocade configuration form • Enter the configDownload command, without the -vf operand, to download the regular configuration data. This step does not cause a reboot. However, the configDownload command issues a notice that "A switch reboot is required for the changes to take effect." There is no reliable mechanism to determine, which parameters may or may not require a reboot.

5 Firmware download issues NOTE This message only appears with Fabric OS v7.1.0 and earlier versions. Symptom The blade is faulty (issue slotShow to confirm). Probable cause and recommended action If the port or application blade is faulty, enter the slotPowerOff and slotPowerOn commands for the port or application blade. If the port or application blade still appears to be faulty, remove it and re-insert it into the chassis.
Firmware download issues 5 Wait at least 15 minutes for the commit operation to complete, then use the firmwareShow command to verify the partitions are synchronized. In some older versions of firmware, the firmware commit operation may not be started automatically on the switch (or on the standby CP in the director). In this case, you can enter the firmwareCommit command manually on the switch (or on the standby CP in the director) to synchronize the partitions.
5 Firmware download issues Symptom Cannot download the requested firmware. Probable cause and recommended action The firmware you are trying to download on the switch is incompatible. Check the firmware version against the switch type. If the firmware is incompatible, retrieve the correct firmware version and try again. Example of error message SW3900:admin> firmwaredownload Server Name or IP Address: 192.168.126.115 User Name: userFoo File Name: /users/home/userFoo/firmware/v7.1.
Troubleshooting with the firmwareDownload command 5 Troubleshooting with the firmwareDownload command A network diagnostic script and preinstallation check is a part of the firmware download procedure. The script and preinstallation check performs troubleshooting and automatically checks for any blocking conditions. If the firmware download fails, refer to the Fabric OS Message Reference for details about error messages. Also refer to, “Considerations for downgrading firmware” on page 56.
5 USB error handling USB error handling Table 11 outlines how the USB device handles errors under specific scenarios and details what actions you should take after the error occurs. TABLE 11 USB error handling Scenario under which download fails Error handling Action An access error occurs during firmware download because the removal of the USB device, or USB device hardware failure, and so on. Firmware download times out and commit is started to repair the partitions of the CPUs that are affected.
Considerations for downgrading firmware 5 Upgrade to 7.2 is not allowed since base switch has R_RDY enabled ports. Please disable the R_RDY enabled ports in base switch using portcfgislmode command. Firmware upgrade to Fabric OS 7.2.0 or higher is not allowed when there are more than 4 chassis connected through Inter-Chassis Links (ICLs) and the Enterprise ICL (EICL) license is not installed in the system. Note that even with an EICL license installed, only 9 chassis are allowed to connect through ICLs.
5 Considerations for downgrading firmware Downgrade is not allowed because there are few ports other than the first octet of the blade/switch configured for 10G/N10 speeds.Please change the octet speed combo of those ports to 1 using "portcfgoctetspeedcombo" CLI and change their speeds using "portcfgspeed" CLI. Downgrade is not allowed because Monitoring and Alerting Policy Suite (MAPS) is enabled. Please disable MAPS using "mapsconfig --disable" before proceeding. Downgrade to pre-7.
Considerations for downgrading firmware 5 Blade types Where blades are incompatible with a firmware download, they must be removed or powered off before a firmware download begins, as noted in the following message. Message The FC10-6 (type 39) blade is not supported by the target firmware. Please use slotshow to find out which slot it is in and remove it first. Probable cause and recommended action The firmware download operation was attempting to upgrade a system to Fabric OS v7.2.
5 Considerations for downgrading firmware Platform The following system message pertains to switch features or fabric-wide settings that must be removed or disabled before downgrading the firmware. Message Downgrade is not allowed because VF is enabled. Please run "lscfg - -config" and "lscfg - -delete" commands to remove the non-default LS first, then run "fosconfig - -disable vf" to disable VF before proceeding.

7 Fabric identification issues • Admin Domains are mutually exclusive with Virtual Fabrics. When Virtual Fabrics is enabled, all access control is based on the Virtual Fabrics context. • Traffic Isolation zones with no failover option are not supported in logical fabrics. TI zones defined in the base fabric for logical fabric traffic must allow failover. NOTE The configure command has a “Disable FID check” fabric parameter option, which can be used to disable the FID check for FICON logical switches.
Base switch issues Symptom 7 The switch with domain with firmware version has joined the FID fabric and may not be compatible with XISL use. Probable cause and recommended action This message indicates the specified switch in the logical fabric that is using XISLs is running an incompatible firmware version and must be upgraded to Fabric OS v6.2.0 or later. Base switch issues All logical switches in a fabric should have the same base switch attribute.
7 Logical switch issues Logical switch issues CAUTION When a logical switch is created, all configuration for the logical switch is set to factory defaults. When a logical switch is deleted, all configuration for the logical switch is deleted permanently and is not recoverable. Symptom The indicated slot is empty. Probable cause and recommended action You used the lsCfg command and an empty slot was specified. Re-issue the command with the appropriate slot number.
Switch configuration blade compatibility Symptom 7 A non-GE blade is within the slot range. Probable cause and recommended action You are attempting to configure a GE port on a slot that does not contain GE ports. Symptom A port or ports is already in the current switch. Probable cause and recommended action You may not move a port to the same switch. Symptom The maximum number of switches for this platform has been reached.
7 Gathering additional information Use the lsCfg –restore_slot_to_default command to correct the problem. Once the configuration discrepancy has been fixed, you may use slotPowerOff followed by slotPowerOn to recover.

9 Segmented fabrics If you enter the cfgShow command to display information about all zones, the TI zones appear in the defined zone configuration only and do not appear in the effective zone configuration. 1. Connect to the switch and log in as admin. 2. Enter the zone --show command where .name is the name of the zone to be displayed. If the name is omitted, the command displays information about all TI zones in the defined configuration.
Zone conflicts Symptom 9 Zone conflict appears in logs and fabric is segmented. Probable cause and recommended action This issue is usually caused by incompatible zoning configurations. Verify the following is true: • The effective cfg (zone set) on each end of the segmented ISL is identical. • Any zone object with the same name has the same entries in the same sequence. Symptom Fabric segmentation is caused by a “configuration mismatch”.
9 Zone conflicts TABLE 14 Commands for debugging zoning (Continued) Command Function cfgDisable Disables the active (effective) configuration cfgEnable Use to enable and activate (make effective) the specified configuration. cfgSave Use to save changes to the zone configuration database. cfgTransAbort Use to abort the current zoning transaction without committing it. cfgTransShow Use to display the ID of the current zoning transaction.
Zone conflicts 9 Correcting a fabric merge problem quickly 1. Determine which switches have the incorrect zoning configuration; then, log in to the switches as admin. 2. Enter the switchDisable command on all problem switches. 3. Enter the cfgDisable command on each switch. 4. Enter the cfgClear command on each switch. 5. Enter the cfgSave command on each switch to commit the change. ATTENTION The cfgClear command clears the zoning database on the switch where the command is run. 6.
9 Zone conflicts If the zoneset members between two switches are not listed in the same order in both configurations, the configurations are considered a mismatch; this results in the switches being segmented in the fabric. For example: [cfg1 = z1; z2]is different from [cfg1 = z2; z1], even though the members of the configuration are the same. One simple approach to making sure that the zoneset members are in the same order is to keep the members in alphabetical order. Reordering the zone member list 1.

9 Gathering additional information • If they are in the same zone, perform the following tasks: Enter the portCamShow command on the host port to verify that the target is present. Enter the portCamShow command on the target. Enter the nsZoneMember command with the port ID for the zoned devices on the host and target to determine whether the name server is aware that these devices are zoned together. 3. Resolve zoning conflicts by putting the devices into the same zoning configuration. 4.

Appendix Hexadecimal Conversion B Hexadecimal overview Hexadecimal, also known as hex, is a numeral system with a base of 16, usually written by means of symbols 0–9 and A–F (or a–f). Its primary purpose is to represent the binary code that computers interpret in a format easier for humans to remember. It acts as a form of shorthand, in which one hexadecimal digit takes the place of four binary bits.
