This does indeed let me run it, so it doesn't crash anymore, but my T3's are not measured for some reason.. In fact, there not in the legend of the relevant graphs...
The T3's are configured using disksuite. Our Sysadmin has been working with disk sets on that one... On top of that volume, there is a Veritas File System...
When I do an "iostat -xtc 10" , this is what it gives me back:

On the graphs however, only the following show up: md10, md20, md0, md11, md21, md1
The 1/md110 & 2/120 for instance (which are mirrorred volumes that are used) don't show up ...
Looking at the build-up using "metastat": (-s <diskset> )
root at emtc02# metastat -s emtc01-ds2
emtc01-ds2/d120: Mirror

The reason I started working with Orca, is because I thought I could use it to monitor that specific volume... duh :-)
This will require some more fiddling I suppose, thanks for any comments made...
Kind regards,
Renaat
