Example of moving volumes to disk partitions on Solaris

This example shows how to move the data on a volume to a disk partition. In the example, there are three disks: disk1 and disk2 are subdisks on volume vol01 and disk3 is a free disk. The data on vol01 is copied to disk3 using the vxevac command.

These are the contents of the disk group voldg before the data on vol01 is copied to disk3.

Remove the evacuated disks from VxVM control.

# vxdg rmdisk disk1
# vxdg rmdisk disk2
# vxdisk rm c1t12d0
# vxdisk rm c1t14d0

Verify that the evacuated disks have been removed from VxVM control.

# vxdisk -g voldg list
DEVICE       TYPE      DISK         GROUP        STATUS

Check to see whether the volume you want to move first is mounted.

# mount | grep vol1
/vol1 on /dev/vx/dsk/voldg/vol1
read/write/setuid/log/nolargefiles/dev=12dc138 on Wed Apr  
3 10:13:11 2002

Create a partition on free disk space of the same size as the volume. In this example, a 2G partition is created on disk1 (c1t12d0s1).

Copy the data on vol01 to the newly created disk partition.

# dd if=/dev/vx/dsk/voldg/vol01 of=/dev/dsk/c1t12d0s1

In the /etc/vfstab file, remove the following entry.

/dev/vx/dsk/voldg/vol1 /dev/vx/rdsk/voldg/vol1 /vol1 vxfs 4 yes rw

Replace it with an entry for the newly created partition.

/dev/dsk/c1t12d0s1 /dev/rdsk/c1t12d0s1 /vol01 vxfs 4  yes rw

Mount the disk partition.

# mount -F vxfs /dev/dsk/c1t12d0s1 /vol01

Remove vol01 from VxVM.

# vxedit -rf -g voldg rm /dev/vx/dsk/voldg/vol01

To complete the procedure, follow the remaining steps.
