hello senthil,
through ioscan you can get disk path info and then through diskinfo can get size info for disk.

other way is you can run sam > disk and file system > disk devices can get all info,

thanks,

Hi Senthil,

Best way is the "diskinfo" command as mentioned above.

Another way is the "pvdisplay" as below:

# pvdisplay /dev/dsk/c0t1d0
--- Physical volumes ---
PV Name /dev/dsk/c0t1d0
VG Name /dev/vg01
PV Status available
Allocatable yes
VGDA 2
Cur LV 1
PE Size (Mbytes) 4 <----
Total PE 4340 <----
Free PE 4336
Allocated PE 4
Stale PE 0
IO Timeout (Seconds) default
Autoswitch On

=========================
So, the disk size will be:
SIZE = Total PE * PE Size
= 4340 * 4 MB
= 17360 MB
=========================


Regds,

Hi Senthil,

You can check everything from nickel output

#cd /opt/contrib/bin

Dear Senthil

diskinfo is the command

Hi,

Other than diskinfo, you could use this also to find out the disk size.

# pvdisplay /dev/dsk/c1t2d0 |egrep "PE Size|Total PE"
PE Size (Mbytes) 8
Total PE 2170
#

PE Size * Total PE => Total disk size
