I may have 10 - 100 servers that all have a volume /u01 and all have /var, /usr, etc...
when testing alerts on volume monitoring, I can select a node that I know I am monitoring volumes, but then selecting a volume means that I have to know what volumes I am monitoring on that box - the drop down list that shows what volume to test against is all volumes that are being monitored from all machines. The drop down should only include those volumes that are relevant to the node I selected. If I goof and select a volume not on that server, then errors were occur.
