Environment

VMware NSX

Cause

Corfu write latencies owing to underlay storage issue cause overall cluster instability.

Resolution

The NSX manager node where the SCSI Host Driver issues(mptscsih) are seen is impacted. Move the impacted node out of the host/storage where it is and monitor/ resolve the underlay storage issues.
