To Verify That the Label of a RAID Volume Is Valid

Language:

Note - For your reference, this section provides an example procedure for a SPARC system that runs the Oracle Solaris OS. For an x86 system that runs a supported OS, you would use the fdisk command for that OS to verify the label of a disk. For more information about labeling disks using the fdisk command, see the documentation for your OS.

Become the root user on the system, and issue the format command.
