Veritas Volume Manager (VxVM) provides utilities that you can use to convert objects, file systems, and device partitions controlled by the Sun Microsystems Solaris Volume Manager software (also known as Solstice Disk SuiteTM) software to VxVM control. The tools convert all Solaris Volume Manager objects into VxVM objects and encapsulate file systems and swap device partitions used by Solaris Volume Manager software. The conversion happens in place. You do not need to copy data into temporary storage. After the conversion, the Solaris Volume Manager software is disabled and can be removed.
The conversion utilities have the following characteristics:
/etc/vfstabare put under VxVM control.
metadbfor every diskset, and
prtvtocoutput for all disks.
/etc/vfstabis lost during the conversion. The partition is considered free space when the disk is converted to VxVM control. Even if the partitions are in use, such as for Oracle raw tablespace data, they are not encapsulated during the conversion. The raw partitions are lost when the disk layout changes. Either encapsulate the partition under Solaris Volume Manager control and allow the conversion to convert the resulting metadevice, or back up the partition, plan to create a new volume for it, and restore the partition after the conversion.
