The easiest way is to do a 'diskinfo' on the /dev/rdsk/c?t?d? device file. That will give you the disk size and from there you can calculate the GB size of the disk.

# diskinfo /dev/rdsk/c8t0d2
SCSI describe of /dev/rdsk/c8t0d2:
vendor: HP
product id: A6218A
type: direct access
size: 37748736 Kbytes
bytes per sector: 512

From here you can get the size in GB by dividing the size by 1,048,576.

37,748,736 KB / 1,048,576 = 36 GB

echo "selclass qualifier disk;info;wait;infolog" | cstm

-or-

Patrick's works just as well.

"man df"? I assume that you can get from KB
("df -k") to GB.

HI,

The df -k command shows the harddisk capacity in kb not in GB

Hi Logesh ,
To get the disk size in GB use the command:
diskinfo /dev/rdsk/c2t0d0s2 |grep size: > /tmp/sad;A=$(cat /tmp/sad |grep size: | awk '/ / {print $2}');Z=1024;(( B = A / Z ));(( C = B / Z ));echo "$C GB"
-where /dev/rdsk/c2t0d0s2 is the device file of the disk. You can use it as a script.

Davis Paul.

Logesh,
Where you looking for a truncated integer result or a fractional result?
How do you see your 'harddisk'?
df?
pvdisplay?
diskinfo?
What works for you?

Steve>> "man df"? I assume that you can get from KB
("df -k") to GB.

I don't think Logesh can. That's the problem.
Also, df can do the nastly line split making scripts trickier.

diskinfo /dev/rdsk/c2t0d0s2 |grep size: > /tmp/sad;A=$(cat /tmp/sad |grep size: | awk '/ / {print $2}');Z=1024;(( B = A / Z ));(( C = B / Z ));echo "$C GB"

10 points for entertainment!
0 points for efficiency

untested (as I have no privs here...)

# let size_in_gb=$(diskinfo -b)/1024/1024

>> cat /tmp/sad |grep size: | awk '/ / {print $2}'

awk is happy to read the file (or pipe) itself
awk is made to grep itself

awk '/size/{ print $2}' /tmp/sad

and why use an intermediate file, or that redundant grep?

A=$(diskinfo /dev/rdsk/c2t0d0s2 |awk '/size/{ print $2}');Z=1024;(( B = A / Z ));(( C = B / Z ));echo "$C GB"

The Z intermediete only obfuscates.

But in the end... Just ask diskinfo for the size alone!

hein.
