Hi All,

I am trying to mirror on my Solaris SPARC 8 machine.
I have 6 HDD of 73 GB. I have my OS on the disk 0 and
I am for the time trying to mirror it with Disk1. I
have root 63 GB, swap 7 Gb and two slices for the
state database replicas.

I gave

metadb -a -f -c2 /dev/dsk/c1t0d0s3 /dev/dsk/c1t1d0s3
metadb -a -f -c2 /dev/dsk/c1t0d0s4 /dev/dsk/c1t1d0s4
Thses 2 are my state database replicas (each 0.5 GB).

I created the mirrior using
# metainit -f d10 1 1 c0t10d0s0
d10: Concat/Stripe is setup
# metainit -f d20 1 1 c0t11d0s0
d20: Concat/Stripe is setup
# metainit d30 -m d10
d30: Mirror is setup

Then to get it updated in the vfstab i gave
metaroot d30.
There was a change in my vfstab
/dev/md/dsk/d30 /dev/md/rdsk/d30 / ufs 1 no -.

I tried mirroring the swap in the same way. I then
reboted the sytem after manually changing the entry on
the vfstab for the swap. I am not able to boot the
sytem. There is no error on the screen but the system
hangs after the detection of the HDD.

I does not give me any error messgaes.
Please do let me know whether is the pblm with respect
to the mirroring or is any entry on the vfstab got
screwed. Please do let me know how to correct it if it
has gone wrong. ANd also please let me know if there
is any thing worng in my configuration steps. I have
not given the metaattach command.

Girish
