Use the prtvtoc and fmthard commands to label multiple disks with the same disk geometry.
Use the following for loop in a script to copy a disk label from one disk and replicate it on multiple disks.
# for i in x y z > do > prtvtoc /dev/rdsk/cwtxdysz | fmthard -s - /dev/rdsk/cwt${i}d0s2 > done
Example 11-9 Labeling Multiple Disks
In this example, the disk label from c2t0d0s0 is copied to four other disks.
# for i in 1 2 3 5 > do > prtvtoc /dev/rdsk/c2t0d0s0 | fmthard -s - /dev/rdsk/c2t${i}d0s2 > done fmthard: New volume table of contents now in place. fmthard: New volume table of contents now in place. fmthard: New volume table of contents now in place. fmthard: New volume table of contents now in place. #
