Hi,

How do you have your drives mounted?

/opt/nagios/libexec/check_iostat_orig -d emcpower3001a -w 1,2,3 -c 2,3,4
ERROR: Device incorrectly specified

What is the result if you run /opt/nagios/libexec/check_iostat_orig -d /dev/rdsk -w 1,2,3 -c 2,3,4?

It looks like script was hard coded to only test devices under /dev
to fix that, edit the script and change the following line from

Code: Select all

[ ! -b "/dev/$disk" ] && echo "ERROR: Device incorrectly specified" && help

to

Code: Select all

[ ! -d "$disk" ] && echo "ERROR: Device incorrectly specified" && help

Save it and see if that works for you.

If this doesn't work, you may want to contact the author of the plugin.

Hi,

i modified the script and it's working now.
i compare the disk name between (iostat -nx) and /dev/dsk to be able read the path with correct device name.

Good to hear! Are we good to mark this thread as resolved then?

[murawweh.daher]

yes, solved
