Tools > File Systems > Label Disks

Each drive used by StorNext must be labeled.

Note: A new drive must be labeled only one time.

You can label a drive from any StorNext server or client that has a fibre channel (FC) connection to the drive. The two types of labels are EFI and VTOC.

Label Type Description


EFI labels are required if you plan to create LUNs that are larger than 2TB.

Note: For Solaris, EFI labels are also required for LUNs with a raw capacity greater than 1TB. EFI labels will not work with the IRIX operating system.

EFI labels are the default for StorNext.


VTOC labels are used for all operating systems in previous StorNext and Xsan releases, and are still required for the SGI IRIX operating system, Solaris releases prior to Solaris 10 Update 2, and LUNs less than 1TB.
