Hi All,
I for the life of me cannot get software RAID-1 going on the root file-system. I've followed the instructions in Solaris Volume Manager Admin. Guide and I think I'm doing it right. This is in a Sun V240 with two 137GB drives.
I basically do the following:
Disk0 - c1t0d0s0
Disk1 - c1t0d1s0
prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
prtvtoc /dev/rdsk/c1t1d0s2 (Double check that disk 1 looks like disk 2)
metadb -af -c 2 /dev/rdsk/c1t0d0s3 /dev/rdsk/c1t0d0s4
metadb -af -c 2 /dev/rdsk/c1t1d0s3 /dev/rdsk/c1t1d0s4
metainit -f d10 1 1 /dev/rdsk/c1t0d0s0
metainit -f d20 1 1 /dev/rdsk/c1t1d0s0
metainit d0 -m d10
metaroot d0
lockfs -fa
reboot
......
Before I reboot, I do a metastat and it shows the following:
# metastat
d0: Mirror
Submirror 0: d10
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 20494464 blocks (9.8 GB)
d10: Submirror of d0
State: Okay
Size: 20494464 blocks (9.8 GB)
Stripe 0:
Device Start Block Dbase State Reloc Hot Spare
c1t0d0s0 0 No Okay Yes
d20: Concat/Stripe
Size: 20494464 blocks (9.8 GB)
Stripe 0:
Device Start Block Dbase Reloc
c1t1d0s0 0 No Yes
Upon reboot, I get this:

HELP! What am I doing wrong? Thanks!
