Moving a JFS FIle to a New Volume Group
1. backup data you intend to migrate
2. unmount fs where lv resides
3. copy the source logical volume to the desired volume group with the cplv
command.
For example, where myvg is the NEW volume group and mylv is the name of
the user's
logical volume, enter:
cplv -v myvg mylv
4. All JFS require a log device. If JFS log does not already exists on the
new volume group,
mklv -t jfslog myvg 1
This will return a new jfslog such as loglv00. This will need to be
reformatted with the
logform command to function as a JFS log.
logform /dev/loglv00
5. Change the filesystem to reference a log device that exists in the new vg
and the new
logical volume with the chfs command.
For example where myfilesystem is the name of the user's filesystem,
enter:
chfs -a dev=/dev/lv00 -a log=/dev/loglv00 /myfilesystem
6. RUn fsck to ensure filesystem integrity,
fsck -p /dev/lv00
7. Mount the file system. For example, where myfilesystem is the name of the
user's
file system, enter:
mount /myfilesystem
At this point the migration is complete and any applications or users can
now access the
data in this filesystem. To change the logical volume name, proceed to
step 8. Note: If
you receive errors from the preceding step do not continue, contact AIX
support center.
8. Remove the source logical volume with the rmlv command:
rmlv mylv
9. Rename and reset any needed attributes on the new logical volume with the
chlv or chmod commands.
For example, where mylv is the name of the user's logical volume, enter:
chlv -n mylv lv00

Hi,
I am looking for best method/command/steps to move all the user filesystems
from jdadata volumegroup to a new volumegroup jdadata1.
current raid array needs to be rebuilt since we have issues on the raid
array.
fortunately we are adding a new diskarray.
help apperciated.
I have looked at using WSM, smit backup and restore.
