Here are the steps I used to clone the root filesystem to a new volume
Shutdown Linux
Performed a complete full volume backup of original dasd
Restored disk units to new drive assignments
Started Linux
Logged and became root
Execute "cd /sys/devices/css0" sans quotes
Ran "echo 1 > `find | grep 2505 | grep online`" sans double quotes
Ran "cat /proc/dasd/devices" sans quotes which returned the
following:
1 0.0.1242(ECKD) at ( 94: 0) is dasda : active at
blocksize: 4096, 601020 blocks, 2347 MB
2 0.0.150e(ECKD) at ( 94: 4) is dasdb : active at
blocksize: 4096, 1803060 blocks, 7043 MB
3 0.0.1611(ECKD) at ( 94: 8) is dasdc : active at
blocksize: 4096, 601020 blocks, 2347 MB
4 0.0.113e(ECKD) at ( 94: 12) is dasdd : active at
blocksize: 4096, 601020 blocks, 2347 MB
5 0.0.2505(ECKD) at ( 94: 16) is dasde : active at
blocksize: 4096, 1803060 blocks, 7043 MB
where dasde is the new device on disk unit address 2505 on line 5
Ran "dasdfmt -b 4096 -v -f /dev/dasde" sans quotes to prepare the
disk to receive the data.
Ran "fdasd /dev/dasde" sans quotes and made 3 partitions, for "/",
"/boot", and swap
Ran "mke2fs -b 4096 /dev/dasde1" sans quotes for the "/boot"
partition making it an ext2 filesystem
Ran "mke2fs -j -b 4096 /dev/dasde2" sans quotes for the "/"
partition making it a journal ext3 filesystem
Used /mntboot as a temporary mount point and mounted the DASD volume
on it using "mount /dev/dasde1 /mntboot" sans quotes
Used /mnt as a temporary mount point and mounted the DASD volume on
it using "mount /dev/dasde2 /mnt" sans quotes
Typed "cd /" sans quotes and hit enter
Ran "tar -clpSf - . | (cd /mnt ; tar -xpSf - )" sans quotes to copy
the current root file system to the new volume
Type "cd /boot" sans quotes and hit enter
Ran "tar -clpSf - . | (cd /mntboot ; tar -xpSf - )" to copy the boot
information
Typed "cd /" sans quotes and hit enter
Ran "umount mntboot" to remove mntboot
Ran "chroot /mnt" sans quotes
Ran "mount /mnt/boot /dev/dasde1" sans quotes to put
Reviewed /etc/zipl.conf, to verify any device number changes. The
file is contained below. Edited line 12 to include new dasd.

system.
Rebooted system.
