Most VM disks consist of the following regions:
A disk's type identifies how VxVM accesses a disk, and how it manages the disk's private and public regions.
The following disk access types are used by VxVM:
Auto-configured disks (with disk access type auto) support the following disk formats:
The vxcdsconvert utility can be used to convert disks to the cdsdisk format.
See the vxcdsconvert(1M) manual page.
By default, auto-configured non-EFI disks are formatted as cdsdisk disks when they are initialized for use with VxVM. You can change the default format by using the vxdiskadm(1M) command to update the /etc/default/vxdisk
defaults file.
Auto-configured EFI disks are formatted as sliced disks by default.
VxVM initializes each new disk with the smallest possible number of partitions. For non-EFI disks of type sliced, VxVM usually configures partition s3 as the private region, s4 as the public region, and s2 as the entire physical disk. An exception is an encapsulated root disk, on which s3 is usually configured as the public region and s4 as the private region.
