How do I add new DASD to an existing volume group (SLES8)?

grep dasdbl /proc/dasd/devices       # - to find major/minor numbers of device
mknod /dev/dasdbl b 94 
mknod /dev/dasdbl1 b 94 253          # - minor number + 1
dasdfmt -y -f /dev/dasdbl -b 4096 -p
fdasd -a /dev/dasdbl
pvcreate /dev/dasdbl1
vgextend vg00 /dev/dasdbl1

grep dasdbl /proc/dasd/devices # - to find major/minor numbers of device mknod /dev/dasdbl b 94 mknod /dev/dasdbl1 b 94 253 # - minor number + 1 dasdfmt -y -f /dev/dasdbl -b 4096 -p fdasd -a /dev/dasdbl pvcreate /dev/dasdbl1 vgextend vg00 /dev/dasdbl1
