Figure 55 Label Disk Device
Screen
From this screen, you can perform these tasks:
•Select Label Type - Specify VTOC or EFI label types for your
disks. VTOC labels were 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. EFI labels are required if you
plan to create LUNs that are larger than 2TB. (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.
•Label - Label any unused devices or relabel any device
•Unlabel - Unlabel any device in use by the file system
•Probe - Pulse a disk’s activity light
2From the Disk Devices list, select the device you want to label,
unlabel, or probe, and then click Label.
Caution: If you unlabel a device, all data on that device will
be lost. Additionally, the unlabeled device will no
longer be used by a StorNext file system until it is
relabeled.
