Hi All,
My ioscan -fnCdisk output is the following..

disk 1 0/1/1/0.0.0 sdisk CLAIMED DEVICE HP 146 GMAW3147NC
/dev/dsk/c2t0d0 /dev/rdsk/c2t0d0
disk 2 0/1/1/0.1.0 sdisk CLAIMED DEVICE HP 146 GMAW3147NC
/dev/dsk/c2t1d0 /dev/rdsk/c2t1d0
/dev/dsk/c2t1d0s1 /dev/rdsk/c2t1d0s1
/dev/dsk/c2t1d0s2 /dev/rdsk/c2t1d0s2
/dev/dsk/c2t1d0s3 /dev/rdsk/c2t1d0s3

Can you please suggest what the following means and why it is not there with my disk 1??
/dev/dsk/c2t1d0s1 /dev/rdsk/c2t1d0s1
/dev/dsk/c2t1d0s2 /dev/rdsk/c2t1d0s2
/dev/dsk/c2t1d0s3 /dev/rdsk/c2t1d0s3

>>/dev/dsk/c2t1d0s1 /dev/rdsk/c2t1d0s1
>>/dev/dsk/c2t1d0s2 /dev/rdsk/c2t1d0s2
>>/dev/dsk/c2t1d0s3 /dev/rdsk/c2t1d0s3

/dev/dsk/c2t1d0s3 is the bootable disk of your system and it has partitioned in to three s1,s2 and s3

/dev/rdsk/c2t1d0s1 is the EFI partition
/dev/rdsk/c2t1d0s2 is the data/hpux partition (user to build vg00)
/dev/rdsk/c2t1d0s3 HP Special partition for EFI maintenance and offline diagnostics

see man idisk for more details

as described above 3 partitions are need
s1 s2 and s3

there are 3 partitions made in your disk.

hello..
Your system is IPF System. You need to have EFI partition for IPF system to boot an OS and looks your /dev/rdsk/c2t1d0 is bootbable disk.
OS disk will have 3 slices in IPF systems.
c2t1d0s1 - EFI Partition
c2t1d0s2 - HP-UX OS Partition
c2t1d0s3 - HPSP HP service Partition...

Hi

It is only for bootable disk.

It is not for your Data disk.

the slices are not coming as themselves ,

You need to slice it with idisk utility in case if you want to use your new disk as boot disk (o/s disk), then follow the procedure in the doc mentioned in one of the earlier post ..

Dear kunjuttan.....enthuttathe..

use ioscan -efunC disk

If you use this then you can find the boot disk and your data disk in a diffrent format.

in that you will see

s1 -will contain the EFI boot loader and will be commonly known as EFI partition.
s2 will be your OS partition
s3 -which is commonly known as HPSP service partion

ok...
