Figure 58 Label Disk Device
Screen
From this screen, you can perform these tasks:
•Select Label Type - Specify VTOC or EFI label types for your disks. (The default is EFI labels.) 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. If you need help determining label type, click the Label Help link.
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.
•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
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.
