hi,
I have some trouble trying to "clone" a E420.
Problem:
I have an E420 (A) with Sol8 and SDS and 2 36GB disks mirrored. I
want to use one of them to clone exactly this machine on another E420
(B).
My DB replicas are (on A):
ecs148 at root# metadb -i
flags first blk block count
a m p luo 16 1034
/dev/dsk/c0t0d0s3
a p luo 1050 1034
/dev/dsk/c0t0d0s3
a p luo 2084 1034
/dev/dsk/c0t0d0s3
a p luo 16 1034
/dev/dsk/c0t1d0s3
a p luo 1050 1034
/dev/dsk/c0t1d0s3
o - replica active prior to last mddb configuration change
u - replica is up to date
l - locator for this replica was read successfully
c - replica's location was in /etc/lvm/mddb.cf
p - replica's location was patched in kernel
m - replica is master, this is replica selected as input
W - replica has device write errors
a - replica is active, commits are occurring to this replica
M - replica had problem with master blocks
D - replica had problem with data blocks
F - replica had format problems
S - replica is too small to hold current data base
R - replica had device read errors
and my metastat output (on A):
ecs148 at root# metastat
d0: Mirror
Submirror 0: d10
State: Okay
Submirror 1: d20
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 6292242 blocks
d10: Submirror of d0
State: Okay
Size: 6292242 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
c0t0d0s0 0 No Okay
d20: Submirror of d0
State: Okay
Size: 6292242 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
c0t1d0s0 0 No Okay
d1: Mirror
Submirror 0: d11
State: Okay
Submirror 1: d21
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 8389656 blocks
d11: Submirror of d1
State: Okay
Size: 8389656 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
c0t0d0s1 0 No Okay
d21: Submirror of d1
State: Okay
Size: 8389656 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
c0t1d0s1 0 No Okay
So I thought:
1) A: metadetach d0 d10
2) A: metadetach d1 d11
3) A: now I can remove c0t0d0
4) B: boot the other E420 using the previous disk
5) B: rebuild the mirror using an other 36 GB disk with same
partition table
6) B: detach again c0t0d0
7) A: insert on A c0t0d0 disk and attach the mirror
8) B: insert a new 36 GB disk with same partition table and attach
the mirror
What It's wrong .... what's about DB Replicas
Thanks to everyone
