Warning: No Disk Label

o51974 · #1 (**permalink**) 09-10-2007

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.
