[...][The array seems a good idea, and i've used arrays briefly in the past. I'm having trouble with IFS though. This is running on Solaris8 using ksh.
You're using ksh88 and ksh88 doesn't support that syntax.
You should either use its supported syntax:
Or use ksh93 (if available under /usr/dt/bin/dtksh):
You don't need to modify IFS in this case.

vgmove
vgmove(1M)vgmove(1M)NAME
vgmove - move data from an old set of disks in a volume group to a new set of disks
SYNOPSIS
autobackup] diskmapfile vg_name
autobackup] diskfile diskmapfile vg_name
DESCRIPTION
The command migrates data from the existing set of disks in a volume group to a new set of disks. After the command completes successfully,
the new set of disks will belong to the same volume group. The command is intended to migrate data on a volume group from old storage to
new storage. The diskmapfile specifies the list of source disks to move data from, and the list of destination disks to move data to. The
user may choose to list only a subset of the existing physical volumes in the volume group that need to be migrated to a new set of disks.
The format of the diskmapfile file is shown below:
source_pv_1 destination_pv_1_1 destination_pv_1_2 ....
source_pv_2 destination_pv_2_1 destination_pv_2_2 ....
....
source_pv_n destination_pv_n_1 destination_pv_n_2 ....
If a destination disk is not already part of the volume group, it will be added using see vgextend(1M). Upon successful completion of the
source disk will be automatically removed from the volume group using see vgreduce(1M).
After successful migration, the destination disks are added to the LVM configuration files; namely, or The source disks along with their
alternate links are removed from the LVM configuration files.
A sample diskmapfile is shown below:
/dev/disk/disk1 /dev/disk/disk51 /dev/disk/disk52
/dev/disk/disk2 /dev/disk/disk51
/dev/disk/disk3 /dev/disk/disk53
The diskmapfile can be manually created, or it can be automatically generated using the diskfile and diskmapfile options. The argument
diskfile contains a list of destination disks, one per line such as the sample file below:
/dev/disk/disk51
/dev/disk/disk52
/dev/disk/disk53
When the option is given, reads a list of destination disks from diskfile, generates the source to destination mapping, and saves it to
diskmapfile.
The volume group must be activated before running the command. If the command is interrupted before it completes, the volume group is in
the same state it was at the beginning of the command. The migration can be continued by running the command with the same options and
disk mapping file.
Options and Arguments
The command recognizes the following options and arguments:
vg_name The path name of the volume group.
Set automatic backup for this invocation of
autobackup can have one of the following values:
Automatically back up configuration changes made to the volume group.
This is the default.
After this command executes, the command is executed for the volume group; see vgcfgbackup(1M).
Do not back up configuration changes this time.
Specify the name of the file containing the
source to destination disk mapping. If the option is also given, will generate the disk mapping and save it to
this filename. (Note that if the diskmapfile already exists, the file will be overwritten). Otherwise, will
perform the data migration using this diskmapfile.
Specify the name of the file containing the
list of destination disks. This option is used with the option to generate the diskmapfile.
When the option is used, no volume group data is moved.
Preview the actions to be taken but do not
move any volume group data.
Shared Volume Group Considerations
For volume group version 1.0 and 2.0, cannot be used if the volume group is activated in shared mode. For volume groups version 2.1 (or
higher), can be performed when activated in either shared, exclusive, or standalone mode.
Note that the daemon must be running on all the nodes sharing a volume group activated in shared mode. See lvmpud(1M).
When a node wants to share the volume group, the user must first execute a if physical volumes were moved in or out of the volume group at
the time the volume group was not activated on that node.
LVM shared mode is currently only available in Serviceguard clusters.
