Hi Mehul

As ram said #diskinfo /dev/rdsk/cXtYdZ
will do.

Even you can use pvdisplay /dev/dsk/cXtYdZ
to collect pv information of the disk,then Multiply PE Size with Total PE to get the total PV size ie disk capacity

Hi
For Checking the filesystem total physical size you can use diskinfo
For getting the total memory use demsg and look for physical memory value

do the following
1-ioscan -funC disk
this command will show you the disks you have and there formula /dev/rmt/cxtxdx
2-then do the following command for all the disks you have
diskinfo /dev/rmt/cxtxdx

Re: Total size of hardisk

HI Mehul,
Yes diskinfo is the right command.
Identify the disk you want to see using:

# ioscan -funC disk

For e.g. i have disk /dev/rdsk/c2t0d0 then it show the output as below:

# diskinfo /dev/rdsk/c2t0d0
SCSI describe of /dev/rdsk/c2t0d0:
vendor: HP 36.4G
product id: ST336753LC
type: direct access
size: 35566480 Kbytes
bytes per sector: 512
#

So my disk is 36.4 GB and i get the formatted disk space of around 34GB.

Hope that helps.
