Page 50: Solving Problems At The Component Level
The key to troubleshooting the SR2122-2 is to isolate the problem on a specific storage router component. The first step is comparing what the storage router is doing to what it should be doing. Because a startup problem is usually attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the storage router.
Page 51: Identifying Startup Problems
Observe the operation of the SR2122-2 and its front-panel LEDs to determine startup problems. LEDs indicate storage router status in the startup sequence. By checking the LEDs, you can determine when and where the storage router failed in the startup sequence.
Page 52: Troubleshooting The Power Supply
If the POWER LED is off after you connect the power supply to a new power source, replace the power cord. ■ If the POWER LED still fails to light when the storage router is connected to a different power source with a new power cord, the power supply is probably faulty.
Page 53: Troubleshooting A Network Or Fibre Channel Port Connection
■ If the LINK LED remains off, the cable is most likely not the problem. Continue to the next step. 2. Check the external end system, switch, or router to which the port is connected. ■ If the external end system, switch, or router is operating properly, continue to the next step.

Any instances with the primary attribute set to the name of the storage router will resume running on the storage router after it is rebooted. If you are not going to reboot the storage router immediately, use the failover scsirouter command to return the desired SCSI routing instances to the storage router.
Page 174: Backing Up System Configuration
Configuration files are normally maintained in the savedconfig directory on the storage router. You can use the copy command to copy the configuration file to a server running TFTP, allowing you to integrate the storage router backups with other software archives.
Page 175: Storing Backups To A Remote Tftp Server
Restoring configuration data copies all or part of the contents of the specified file into persistent memory; it does not always change the storage router's running configuration. For example, the configuration of a restored SCSI routing instance may only be completely visible via the show scsirouter command using the from bootconfig keywords, until the instance has been restarted.

Page 186: Reset To Remove Saved Configuration Files
Reset to Remove Saved Configuration Files Use the following procedure if a standalone storage router has joined a cluster and adopted the new cluster’s configuration. The procedure removes previously saved configuration files from the stand-alone period, but the storage router’s system configuration, management information, and SCSI routing instances remain unchanged.
Page 187: Recovering Passwords
Recovering Passwords The storage router management interface is password protected. You must enter passwords when accessing the storage router via Telnet (for the CLI) or the web-based GUI. Password protection can also be enabled for the storage router console interface, requiring that the same Administrator and Monitor mode passwords that are configured for the management interface be applied to the console interface.
Page 188: Making Changes To Instance Configurations
To assure that changes are correctly propagated to all storage routers within a cluster, always modify the configuration of a SCSI routing instance from the storage router where the instance is currently active. Frequently you will make changes to the SCSI routing instance configurations.
Page 189: Enabling And Disabling Connections
1. enable — Enter Administrator mode. 2. show scsirouter foo stats — Display status to confirm the SCSI routing instance, foo, is active on this storage router. 3. show scsirouter foo — Verify the name and current status of the target and access list.
Page 190: Stopping And Starting Instances
"21:00:00:05:ae:42:2f:12" Stopping and Starting Instances If the storage router is experiencing a problem with a specific set of IP hosts or storage resources, you may wish to stop the associated SCSI routing instance from running anywhere in the cluster. The no scsirouter enable command causes the specified SCSI routing instance to cease running on the storage router, but does not cause a failover to another storage router in the cluster.
Page 191: Viewing Operational Statistics
Use the show scsirouter stats command to display the status of the SCSI routing instance and to see the number of active connections and the number of logins that have occurred since the storage router was last restarted (or since statistics were last cleared).
Page 192: Manual Failover
While failover of SCSI routing instances is automatic, there may be times when you wish to manually move a SCSI routing instance from one storage router to another. The move may be temporary, after which the instance will be moved back to its original location.
Page 193: Failover As Permanent Move
If the instance’s configuration changes while the designated primary storage router for that instance is down (or otherwise removed from the cluster), the changes will not be propagated to that storage router. When the primary storage router reboots (or otherwise returns to the cluster), it will reassert itself as the primary and will start to run the instance using the last configuration it had before leaving the cluster.

Disable CDP for Selected Interfaces CDP can be enabled or disabled for the management, HA, and Gigabit Ethernet interfaces on the storage router. By default, all interfaces are enabled for CDP. To disable CDP for an interface: 1. enable — Enter Administrator mode.
Page 196: Modify The Cdp Holdtime And Timeout Values
Holdtime is the amount of time the receiving device should hold a CDP packet from the storage router before discarding it. The CDP holdtime value must be set to a higher number of seconds than the CDP timer value (the time between CDP transmissions from the storage router).
Page 197: Running Command Scripts
Scripts can be created on any system using any text editor and placed in the script directory (/ata3/script) of the target storage router using FTP. See “Using FTP with the Storage Router” also use the copy command to copy the script file to the storage router using HTTP or TFTP. Running Command Scripts Use the following procedure to execute the CLI commands stored in a script file.
Page 198: Managing The Log File
Managing the Log File The storage router can log event information to a series of log files, based on the routing rules specified in the storage router logging table. The default configuration routes all storage router event messages at notification level info or lower to the log file.
Page 199: Clearing The Log Files
Clearing the Log Files To periodically clear the storage router log files. 1. enable — Enter Administrator mode. 2. show logging size — Check the current size of the storage router log files (Example 3. show logging all or show logging last 50 — Display all the current log file entries (first command), or display a selected number of entries, such as 50, from the end of the file (second command).
Page 200: Using The Crash Log
Maintaining and Managing the Storage Router Using the Crash Log If the storage router experiences an unexpected problem that forces it to automatically reboot, a special log file is generated. The file is named crash.txt and is stored in the log directory (/ata4/log). You can display the contents of this file to the console using the show crash command.
Page 201: Using Ftp With The Storage Router
Using FTP with the Storage Router In certain cases, you may want to copy log files from the storage router to another server in your network for analysis purposes, or you may want to copy configuration or script files to another server prior to making them available to another storage router.
Page 202 The user name and the password are case-sensitive. Note: The storage router log files and crash trace files are stored in the /ata4/log directory. Saved configuration files are stored in the /ata3/savedconfig directory. Script files are stored in the /ata3/script directory.
Page 203: Understanding Diagnostics
Hardware diagnostics cannot be bypassed. If a hardware diagnostic fails, the storage router halts. The boot process cannot be re-initiated. If you experience a hardware diagnostic failure, contact HP technical support personnel as described in the Guide” Chapter for further instructions.
Page 204: Capturing System Messages At Bootup
Maintaining and Managing the Storage Router Capturing System Messages at Bootup The storage router logs a variety of messages to the console during the system boot process. If you are experiencing problems with the storage router, it may be helpful to capture these messages. Use the console interface to perform the boot process and capture the console log using typical external methods.
Page 205 The message is not logged; it is discarded. The message is logged to a serial console CLI session. The message is logged to the storage router log file. The message is logged to a remote syslog server. Use the logging syslog command to specify the IP address of the remote syslog server.
Page 206 By default, the logging table includes rules to log all messages at notification level notice (or numerically lower levels) to all destinations, and to log all messages at notification level info to the storage router log file. Any message that does not find a matching rule is not logged to any destination.
Page 207: Filtering And Routing Event Messages
Any message from the SNMP facility at notification level info, and any message from another facility at notification level info (or lower) would match on the second rule and be sent to the storage router console and log file. All messages from any facility at notification level debug would be discarded.
Page 208: Viewing And Saving The Log File
The storage router includes debug facilities for SCSI routing instances. Running debug traces can impact the operation of the storage router. If you experience problems with a SCSI routing instance that cannot be resolved, HP technical support personnel may ask you to capture some debug traces. They will assist you to properly configure the storage router to accomplish this task.

Page 227: Recommended Host/Storage Configurations
Recommended Host/Storage Configurations This appendix provides a brief overview of recommended host/storage configuration using the HP SR2122-2 IP Storage Router. Three configurations are discussed: ■ FCIP Only, page 228 FCIP with Local iSCSI ■ ■ FCIP with Remote iSCSI IP Storage Router SR2122-2 User Guide...
Page 228: Fcip Only
FCIP Only Two SAN islands may be joined into a single large, geographically dispersed SAN using the HP SR2122-2s as Fibre Channel to IP gateways to translate between Fibre Channel protocol and FCIP protocol. FCIP protocol transmitted over a WAN network is used to extend the connection between the two SAN islands beyond the nominal 10 km maximum length for direct Fibre Channel.
