Hi,
Recently, I have configured my ES-250 Sun Enterprise server to mirror
the two disks using Solstice 4.2 (OS 8)
I was able to mirror the two disks (c0t0d0s.. and c0t12d0s..)
sucessfully.
Each disk lay out as followed
root s0
usr s1
swap s3
opt s4
home s5
var s6
unassigned s7 (is used to contain the state
database)

Everything was working fine until I decided to simulate by
switch the drive and location of these.
Upon powering off the system, I removed c0t0d0 and
placed it in c0t8d0. I then removed c0t12d0
(mirror)and placed it in c0t0d0 and then powering the
system on, I can see the following
Sun Enterprise 250 400MHZ
OpenBoot 3.22 1024 MB Memory ...
Ethernet Address 0:3:ba:.... Host ID ...
Initialize memory
Boot device: disk file and args:
Then it just sit there, like it waiting for something.
I waited and waited for hour and still nothing
changed. I can see the power LED is on and that's
the only LED is lid on the ES.-250, the other 5 LED is off.

I tried to place the disks back to its original location and
boot but it still failed, and resulted the same as mention above.

Now, neither one of these disks (Primary and mirror) boot.
I booted from CD and tried to mount the root by
issuing this command
# mount /dev/dsk/c0t0d0s0 /mnt
and it said
mount: no such device
Mount: can not mount /dev/dsk/c0t0d0s0
I figured if I can mount the root then I can go in and modified
the /etc/vfstab and boot w/o the SVM.
My two questions are
Does anyone know how I can mount this root partition?
This is the only one I can't not mount.
The other slices mount no problem at all.
