Hi,

You could elaperate your questions to provide clear informations to you..

Anyway we will provide based on what we understand.

To find the disks available to the system

#ioscan -fnC disk

To find the details of specific disk.

#diskinfo /dev/rdsk/c0t0d0
#diskinfo -v /dev/rdsk/c0t0d0

To find the details of physical volume. Physical volume is nothing but the disks configured for LVM(Logical Volume manager)

#pvdisplay -v /dev/dsk/c0t0d0

This pvdisplay command provide most of the details which you asked. Like which Volume group this disk belongs, Size in PE's, logical volumes residing on the disk, space occupied by each logical volume, PE mapping to the logical volumes, status of PE's, etc..

Note:PE is nothing but the small partitions of disks. disk's will be divided into multiple PE's to allocate to logical volumes

To know specific logical volume details

#lvdisplay -v /dev/vg00/lvol7

you can use vgdisplay command also to know about volume group details.

#vgdisplay -v vg00
