This chapter explains how to convert your LVM, JFS and JFS2 configuration to a VxVM and VxFS configuration and presents the following main topics:
Converting LVM volume groups to VxVM disk groups
The conversion process also includes the conversion of JFS and JFS2 file systems stored in LVM volume groups to VxFS.
The basic tools for conversion are the VxVM commands, vxconvert and vxdiskadm. The discussion here details how to use these tools and gives some insights into how these tools work.
The disks on your system managed by LVM can be of two types: LVM disks in volume groups, and unused disks.
The former are disks that contain logical volumes and volume groups. Unused disks contain no user data, and are not used by any volume group, but have LVM disk headers written by cfgmgr. Conversion is done differently for these two types of disks.
For unused LVM disks you can use vxdiskadm. For LVM disks in volume groups, the primary tool for conversion is the vxconvert command.
