5. Check the disks:

# olds -mirrored -check_disks

number of external scsi controllers with disks is = 0

number of disks is = 4

. . .

disk:c0t0d0 is partitioned ok disk:c0t1d0 is partitioned ok disk:c0t2d0 is partitioned ok disk:c0t3d0 is partitioned ok Success, checking disks for mirroring.

6. Create system files for the Solstice DiskSuite software:

#olds -mirrored -mk_files

7.Make sure all the disk drives on your system have been recognized.

To do that, read the file /olds/md.tab.new into an editor and locate the #/cms section. It should reflect the precise number of disk drives on your system. The following example shows a total of four disk drives on the system, two in d19 and two in d20:

#metaroot

d11 1 1 c0t0d0s0

d12 1 1 c0t2d0s0

d13 -m d11

#/cms

d19 2 1 /dev/rdsk/c0t0d0s3 1 /dev/rdsk/c0t1d0s1

d20 2 1 /dev/rdsk/c0t2d0s3 1 /dev/rdsk/c0t3d0s1

d21 -m d19

#metaswap

d15 1 1 c0t0d0s4

d16 1 1 c0t2d0s4

d17 -m d15

If there is a discrepancy between what the system should have recognized and what it did recognize, complete the procedure in “The system fails to recognize all disk drives” on page 82, and then return to item 5.
