hi shivkumar

main commands are
#pvdisplay or pvdisplay -v

describe the details of hard disk (c0t0d0s0)

#vgdisplay or vgdisplay -v

every hdd befor making lv it must come under vg.
there can be multiple hdds

#lvdisplay lvdisplay -v

this the thing which is getting mounted. A lv can be there in different hdds but only in ong VG


#fstyp /dev/vg01/lv0l2

this is the command which gives out of the file system which you are using.

bye bye

Hi Shiv

1. For physical volume display use pvdisplay -v pv path

2. For logical volume display use lvdisplay -v lvol name

Mahesh

pvdisplay for physical volume

lvdisplay for logical volume

bdf shows all file systems on the system expect swap

If you have added new disks you will need to do ioscan , then insf -e in order to see the new ones.

ioscan -fnC disk will show you your disk devices.

pvdisplay -v /dev/dsk/yourdiskdevice #you will get the disk device from the ioscan -fnC

diskinfo -v /dev/rdsk/yourdiskdevice #This will show you info about your disk like vendor model size serial ect

vgdisplay -v /dev/vg?? vg?? is the volume group and this will show you the vg info, size, what disks are part of it as well as the volume groups.

lvdisplay -v /dev/vg??/lvol? This will show you details about logical volumes you have.

Bdf shows what filesystems you currently have mounted.

The /etc/fstab file has what files will be automatically mouted when your system boots.
