Label Multiple Disks by Using the prtvtoc and fmthard Commands

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 11–8 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
