91Administering application volumes
Migrating ISP volumes to non-ISP volumes
migrated, their intent is preserved by ISP as for volumes that are created
directly using the
vxassist or vxvoladm commands.
Rules specified on the command line are applied to all the specified volumes.
Using a definitions file allows you to apply different rules to each volume.
Volumes that are specified on the command line are also associated with the
same storage pool. If a storage pool is not specified using the -P option, the
volumes are placed in the data storage pool of the disk group. Using a definitions
file allows the migrated volumes to be placed in different storage pools.
The following example demonstrates how to use a definitions file to migrate two
volumes to separate data and clone storage pools:
vxassist -M migrate <<!!
diskgroup "mydg"
volume "myvol" {
pool "mydatapool"
};
volume "snap_myvol" {
pool "myclonepool"
};
!!
Note the following limitations of the migration operation:
■ All non-ISP volumes that share a set of disks must be migrated in a single
operation.
■ Disks cannot be shared with any volumes that are not listed on the
command line or in a definitions file.
■ Volumes cannot share disks unless these disks are to be located in the same
storage pool.
■ Volumes with a usage type of root, such as those on a root disk that is under
VxVM control, cannot be migrated.
■ The disk group containing the volumes to be migrated must have a version
number of 120 or greater.
Migrating ISP volumes to non-ISP volumes
The vxassist reversemigrate operation allows you to convert ISP volumes to
non-ISP volumes. The converted volumes permanently lose any intent that was
associated with them when they were ISP volumes, and the
vxassist command
cannot be used to administer the configuration of any storage that is associated
with them.
Use the following command to migrate ISP volumes to non-ISP volumes:
