Chapter 15 Troubleshooting Distributed Device Alias Services Initial Troubleshooting Checklist Send documentation comments to [email protected] Commit Failure Messages When a device alias commit fails, review the syslog messages for the switch where the command was issued. Example 15-4 shows that SAP 110 (IVR) failed validation on switch sWWN 20:00:00:0d:ec:04:99:40, which caused the commit to fail. Example 15-5 shows the failure message.

Table 15-1 CLI Commands for Troubleshooting Device Alias Issues CLI Command Description show cfs merge status name device-alias Displays information about the status of the CFS merge for the device alias database. show device-alias database Displays the entire device alias database. show device-alias internal validation info Displays information about the status of the validation process (part of a commit or merge). show device-alias merge status Displays the result of the device alias merge operation, and the reason for the result. show device-alias session status Returns the status of the last CFS command, such as clear, commit or abort. The last action result and reason fields help identify the reason for a failure. show device-alias status Displays configuration information for the device alias service, including whether fabric distribution is enabled, the number of device aliases in the database, lock information, and the database mode (basic or enhanced). Limitations and Restrictions The following limitations and restrictions are associated with the use of device aliases: • Enhanced mode operation is only supported on switches running SAN-OS Release 3.1(1) or later. • Interop mode VSANs do not accept enhanced mode (native alias-based) configurations.
