Which command to find total hard disk space?

Look man for
prtvtoc
and
du -k

Another easy way is to run "iostat -En"  If the disk is a Sun supported disk, it usually says it's size in the "Product" field.

eg... This disk is a 36GB disk in a V480

c1t1d0          Soft Errors: 0 Hard Errors: 0 Transport Errors: 0
Vendor: SEAGATE  Product: ST336704FSUN36G  Revision: 0826 Serial No: 0102D1E7DA Size: 36.42GB <36418595328 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 0 Predictive Failure Analysis: 0

Note how the product code ends in SUN36G - that's the size of the disk.

FYI: format shows the same product code info, but without the error counts etc.

There is one problem with this...older IDE disks didn't have the size part of the product code. However, you can always take the product code and stick it into the
"Search handbook" field at http://sunsolve.sun.com

Oh, and one more thing... if you use Solaris 9, you can use the -h flag for "human readable" in the du, df and ls commands... it makes things so much easier to read file and disk sizes.

Of course, if you want the total space for the system, you would need to add all the values you have collected manually.

Hi,

To see all of the slices on all of the disks the easiest thing is:

prtvtoc /dev/rdsk/*s2

To see all disks do this:

format < /dev/null

Both command should be run as root.

Use this script to get the total diskspace, Used disk space and available disk space.

#!/bin/sh

count=0
for i in `df -k|tail +2|awk '{print $2}'`
do
count=`expr $count + $i`
done
echo "Total Disk Space : $count"

count1=0
for i in `df -k|tail +2|awk '{print $3}'`
do
count1=`expr $count1 + $i`
done
echo "Total Disk Used  : $count1"

count2=0
for i in `df -k|tail +2|awk '{print $4}'`
do
count2=`expr $count2 + $i`
done
echo "Total Available Space : $count2"
                                             

Do you want to know the total space mounted, total space formatted, or total space available on the hard disks?

df -k will show total space mounted
du -k shows the space used and I don't think you asked for that

to get the space formatted and the total space available on the disks themselves you really need to use the command format and select each disk one at a time.

For example, on one of my older servers, I select disk 0, p for partition, then p for print to get;

Total disk cylinders available: 2733 + 2 (reserved cylinders)

Part      Tag    Flag     Cylinders        Size            Blocks
  0       root    wm       0 -   67       50.47MB    (68/0/0)    103360
  1       swap    wu      68 -  404      250.12MB    (337/0/0)   512240
  2     backup    wm       0 - 2732        1.98GB    (2733/0/0) 4154160
  3        var    wm     405 -  836      320.62MB    (432/0/0)   656640
  4        usr    wm     837 - 1510      500.23MB    (674/0/0)  1024480
  5 unassigned    wm    1511 - 2022      380.00MB    (512/0/0)   778240
  6 unassigned    wm       0               0         (0/0/0)          0
  7       home    wm    2023 - 2732      526.95MB    (710/0/0)  1079200

Slice 2 represents the whole drive and we can see this drive has 1.98 GB space available in 2,733 blocks.

Slice (Part) 0 is the root partition taking 50.47MB
Slice 1 is the swap taking 250.12MB
and so on...

To see which slices are mounted you can issue the command...

cat /etc/vfstab

# cat /etc/vfstab
#device         device          mount           FS      fsck    mount   mount
#to mount       to fsck         point           type    pass    at boot options

/dev/md/dsk/d1          /dev/md/rdsk/d1         /data   ufs     2       yes     -
/dev/dsk/c0t0d0s5       /dev/rdsk/c0t0d0s5      /opt    ufs     2       yes     -
swap    -       /tmp    tmpfs   -       yes     -

"df -k" shows how much is either used / free for mounted filesystems, how come prtvtoc does not show this?  Also, what about raw partitions on a disk?

Hello,

To see total disk space used on Solaris 8 and before you can use du -k {some mount point}  as in du -k /var  On Solaris 9 or later you can use du -k also, but you can also use du -h which displays a number in a human understandable format (k,m,g).

One caveot (There is always one).  If you execute this command on a mount point which has another mount point below it, it will add all sub mount points up also.

I.e. du -k / will add all disk space used on you system.

I would like to add to this ,

If you give the command
iostat -E
it will show you every disk on the system with size , and make . You can grep , awk the fields you like for processing . Also will show the disk errors if any , and does not require root access either .
I feel this is the most effective command to get disk space

Thanks for the additional tips.

akhopkar,
That command you have given is really useful. Thanks
