Hi All -

I have a strange issue which is prominent on all servers that have Drobo Elite iSCSI disks attached to them. They are Hyper-V 2008 R2 server's and when opmanager reads there free disk space, it returns a negative value, thus triggering an alarm because it is below my threshold. I know I can just change my threshold to a negative value from a positive value, but I would really like to get this to work the correct way, and not the hackjob wilson way. There are 2 other iSCSI disks attached to Dell San's that reflect the correct values, it appears to only be when iSCSI disk's attached from a drobo elite san's.

 

Has anyone else seen this issue before? If so, do you still have this issue, if not, watch out for this if you decide to try and monitor drobo volumes.
