Isilon VASA alarms

If the VASA service is enabled on an Isilon cluster and the cluster is added as a VMware vSphere API for Storage Awareness (VASA) vendor provider in vCenter, OneFS generates alarms in vSphere.

The following table describes the alarm that OneFS generates:

Alarm name


Thin-provisioned LUN capacity exceeded

There is not enough available space on the cluster to allocate space for writing data to thinly provisioned LUNs. If this condition persists, you will not be able to write to the virtual machine on this cluster. To resolve this issue, you must free storage space on the cluster.
