How to determine what process utilize a disk

[Artyom Voronchihin]

Hello !
My system disk utilization is about 100%. How can i determine what process use the disk with standard HPUX tools ? Unfortunately i don't have commercial tools like Glance.

I thing the command "fuser" is
helpfull here.
After this you could make association
also with "top".

Hi,

Without glance it is a bit more complicated, you can try to find the processes using the filesystem with a tool like lsof.

Hope it helps,

Install the trial version of glance plus for
60 days of evaluation.
This tool will be to you of greater aid and from a easy and graphical way you can obtain all the necessary data.

You can use fuser against each level of the file system (including a file).

fuser /dev/rdsk/cXtYdZ
fuser /dev/dsk/cXtYdZ
fuser /dev/vgXX/lvolY
fuser /
fuser //

Each one will give you different results, but usually the best choice is the lvol.

If you have many drives / filesystems, finding it could be tedious.

Glance is the tool to use. Without Glance, I'd start with 'top' here, to find the process that's taking up so much resource. Top will display not only heavy disk user, but heavy use of entire system.

sar -d 5 5 should show what disk, then strings /etc/lvmtab and more /etc/fstab
to find which disk, then use the fuses as described above

bad typos

fuses should read fuser
