Volume Manager Requirements

If you use Solstice DiskSuite software, you must set aside a slice on the root disk for use in creating the replica database. 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 replica databases in the same slice for Solstice DiskSuite software to function properly. Refer to the Solstice DiskSuite 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 end of the disk. Refer to the VxVM documentation for more information about encapsulation.
