Troubleshooting autoconfiguration failure
Common symptoms of library autoconfiguration failure include the following:
- The library is not listed in the Libraries folder in the Administration interface.
- The library is listed, but is listed as being unconfigured.
Common causes include:
- Device drivers are not properly installed.
- Autodetection fails to match a detected library with its devices due to:
- Out-of-date device firmware.
- Failure of the library to return its devices’ serial numbers.
- Autodetection failed to start on the storage nodes.
- Check for relevant messages.
-
From the command prompt, type the following command to verify that the library returns the serial numbers of its devices:
sn -a b.t.l.
where b.t.l. refers to the bus target LUN of the library. If the bus target LUN is not known, run the inquire command first, to obtain this information.
