Problem in getting total Disk space using iostat -En command
Hi Everyone,

I try to calculate the total hard disk space of a solaris machine using iostat -En command. Iterating the output and summing up all the number present near the Size: will give the exact size of the harddisk. But it is not working for a machine.

This command works in many flavors of solaris. This specific issue is with solaris 5.10 Generic_137137-09 sun4u sparc SUNW,Sun-Fire-V890.

Have attached the sample output of the iostat command's output.

Actual size of the machine is 12272.8 GB, but what i got is 25809 GB.

Kindly let me know, whether the way i calucalating the total hard disk size is wrong or is there any way to remove duplicates from the output and getting the exact size.

Since the output is too longs, i have copied the sample output,

Code:
bash-3.00$ uname -a
SunOS deltabackup01 5.10 Generic_137137-09 sun4u sparc SUNW,Sun-Fire-V890
-bash-3.00$
-bash-3.00$
-bash-3.00$
-bash-3.00$ iostat -En

Kindly let me know if there any other way to get the harddisk size by any other commands.

Thanks,
Prasanna

I think you are calculating the space of mirror disks also..

Hi,

How to remove the mirror disks from the iostat -En command output. Please help.
