On Solaris11U2, /dev/odm may show 'Device busy' status when the system mounts ODM

If the system tries to mount Oracle Disk Manager (ODM) in a mode which is not supported by the installed license, the later ODM mount may not succeed and shows /dev/odm device busy error.

Workaround: There are two ways to resolve it.

Remove /dev/odm mount point and recreate it. Or reboot the system and then mount /dev/odm.
