Hello,
does anybody know if there are best practices about the occupancy of the rdm disks?
I know the threshold alarms in datastores, but I don't know if these applies to rdm disks.
Thanks!
As far as I can tell -- RDMs space utilization cannot be monitored from the VC like datastores - since they are directly accessed by the guest - do you have the monitoring enabled at the VM level?

I'm not worried about the monitoring, I just would know if there is any best practice about the occupancy level of the rdm.
No different than any other device in the VM - e.g. its dependent on application, operating system, etc.
So is there no problem to have an rdm near 100% full?
it may/will crash the DB/App using the RDM lun with in the guest OS - it will not affect any other guests - unlike if a datastore were full
helps??
VMware / ESXi doesn't care.
Your application or array might, but that depends on your application and array.
