Warning: No Disk Label

UNIX Solaris
1

Hi Fellows,

I am trying to mirror 2 identical disks on a SUN Ultra 10 machines (with new installation of Solaris 8). In the process, I found 2 issues:

  1. prtvtoc /dev/rdsk/c0t0d0s0 | fmthard -s - /dev/rdsk/c0t1d0s0
    Result: Disk partitions between the 2 disks do not match up.

  2. manually configure c0t1d0 to match drive partitions on c0t0d0
    Result: "Warning: No Disk Label"

Other info:
a. fsck on both disks/slices results are normal w/o error.
b. both disks are exactly the same.

Thank you. Any ideas would be appreciated.

format /dev/dsk/c0t1d0 to put a disk label on the disk. It may even want you to lay out the rest of the partitions.

I fixed it. Here is what I have done.

  1. delete all partitions on c0t1d0 but backup
  2. newfs /dev/rdsk/c0t1d0s2 (backup)
  3. create partitions to match c0t0d0
  4. label it.
    Done.

Hope this might help other fellows that bump into this.
