Volume Manager Requirements

If you use Solstice DiskSuite/Solaris Volume Manager software, you must set aside a slice on the root disk for use in creating the state database replica. Specifically, set aside a slice for this purpose on each local disk. But, if you only have one local disk on a node, you might need to create three state database replicas in the same slice for Solstice DiskSuite/Solaris Volume Manager software to function properly. See the Solstice DiskSuite/Solaris Volume Manager documentation for more information.

If you use VxVM and you intend to encapsulate the root disk, you need two unused slices available for use by VxVM, as well as some additional unassigned free space at either the beginning or the end of the disk. See the VxVM documentation for more information about root disk encapsulation.
