[Sunhelp] Problem in booting from a mirror disk8 in a UE-250 server.

[English, John]

Srikanta,

I have found that the dd command works best when copying a boot disk, if you
boot cdrom standalone ( boot cdrom -s ). The dd command apparently doesn't
copy over the disk boot blocks 'if' you are running the dd command from the
disk you are copying from. By booting cdrom standalone, the running the dd
command the boot disk is treated as just and disk, and a full copy is made.
Also the disks must be the same , size , sectors, cylinders etc..

Hope this helps..

Dear Experts!

I have a UE-250 server loaded with Sol.2.6 on boot disk0 . I did mirror of
the
boot disk using simple dd command to disk8. And if I try to boot from disk 8
by
giving command  boot disk8 from ok prompt it says Can't boot disk device
disk8 &
it looks for some file to be key in.

UE-250 servers has target ids. like this way...target 8,9,a,b,c,d
I tried with all possibles, but can't boot. Whereas I have already done the
same
in a UE-450 server & it works fine ( with mirror disk target-1)
Can anybody suggest me how will it work ?

Thanking You.

Regards.

Mr.Srikanta.
