Figure 57  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
2
From 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.
