Resolving Unnamed Devices Error Message

If you add new hardware or move hardware (for example, move a string of disks from one controller to another controller), Solaris Volume Manager will check the device IDs associated with the disks that moved, and update the c*t*d* names in internal Solaris Volume Manager records accordingly. If the records cannot be updated, the boot processes spawned by /etc/rc2.d/S95svm.sync (linked to /etc/init.d/svm.sync) will report an error to the console at boot time:

Unable to resolve unnamed devices for volume management.
Please refer to the Solaris Volume Manager documentation,
Troubleshooting section, at http://docs.sun.com or from
your local copy."

No data loss has occured, and none will occur as a direct result of this problem. This error message indicates that the Solaris Volume Manager name records have been only partially updated, so output from the metastat command will likely show some of the c*t*d* names previously used, and some of the c*t*d* names reflecting the state after the move.

If you need to update your Solaris Volume Manager configuration while this condition exists, you must use the c*t*d* names reported by the metastat command when you issue any meta* commands.

If this error condition occurs, you can do one of the following to resolve the condition:

• Restore all disks to their original locations. Next, do a reconfiguration reboot, or run (as a single command):

  /usr/sbin/devfsadm && /usr/sbin/metadevadm -r

  After these commands complete, the error condition will be resolved and you can continue.

• Contact your support representative for guidance

  Note –

  This error condition is quite unlikely to occur. If it does occur, it is most likely to affect Fiber Channel-attached storage.
