A new feature of Volume Manager 5.0 is the support of LUNs larger than 2TB with EFI disks, however, they are not supported for use with the default format, Cross-platform Data Sharing (CDS) compatibility format or for encapsulation.

Volume Manager only supports the initializing of a LUN that is greater than 2TB in the sliced or simple format. However, initializing a LUN that is greater that 2TB and the full capacity of the LUN is a known issued documented in incident 898242. This issue occurs because the initialization process incorrectly calculates the size of the LUN.

To initialize a disk in a format other than the default of CDS, use either of the below commands:

 

# /etc/vx/bin/vxdisksetup -i sdX format=sliced
 

# /etc/vx/bin/vxdisksetup -i sdX format=simple
 

For more information on the supported disk formats, please refer to the Volume Manager Administrator's Guide: Disk Devices: Private and public disk regions, located in the Related Documents section below.

To obtain the fix for Volume Manager incorrectly calculating the size of a LUN that is greater than 2TB, please contact Veritas Technical Support and refer to incident number below.
