Hi All,

pvdisplay those disks and verify they are attached to any VG or not.

#pvdisplay dev/dsk/c0t0d0s1
#pvdisplay dev/dsk/c0t0d0s2
#pvdisplay dev/dsk/c0t0d0s3

Hi Indrajit,

man idisk
man efi

The slice 1, 2 and 3 are the partitions used in the itanium servers.

efi_ls -d /dev/rdsk/c0t0d0s1
efi_ls -d /dev/rdsk/c0t0d0s3

This disk is partitioned using idisk utility to 3 slices - 1 for EFI, 2 for HP-UX (LVM) and 3rd for HPSP.

What you see is the normal disk layout for an Integrity.

3 partitions as follows:

EFI 500MB - boot partition
HPUX 100%
HPSP 400MB - service partition
