Performance Manager is unable to monitor or collect statistics for a volume

JoseJ — Wed, 04 Jun 2025 20:33:01 GMT

Hi All !

We have OPM 1.1.0p1 can't upgrade by the moment due to VMware version limit.

OPM is monitoring a metrocluster system, two clusters with two nodes each one. CDOT 8.3.1p1

One node has a SVM with 25 volumes configured.

All this volumes has been created using the same command using CLI.

OPM is monitoring correctly 21 of this volumes, but there are 4 volumes that OPM can't monitor, and when we filter volumes from dashboard OPM answers:

"Performance Manager is unable to monitor or collect statistics for a volume if the following are true:
• It is a data protection copy, such as a snapshot, in read-only mode.
• It is an Infinite Volume.
• It is an offline data clone.
• It is a mirrored volume in a MetroCluster configuration"

Need help to address this issue...

Thanks in advance.

hi, just try to help. is that possible that all these 4 volumes are the case OPM's listed? as opm can monitor other 21 volumes.

ok, this is just what is driving me crazy.... all the volumes owned by that SVM has been generated using command line (not gui) and using the same command, modifiying for every case the volume's name. I don't understand why OPM makes differences between this four volumes and the other 21.

Thanks for your help,
