ESA evaluates available capacity and fault domains to satisfy policy compliance.

vSAN detects the failure and marks affected objects as non-compliant.

Resync completes and objects transition to Compliant status.

New components are instantiated on eligible capacity devices, and resync begins.

A failed NVMe device in a vSAN ESA cluster is handled as a storage pool device failure. vSAN first detects the failure and marks affected objects as non-compliant when their assigned storage policy requirements are no longer satisfied. ESA then evaluates available capacity and fault domains to determine whether replacement components can be placed in a way that restores compliance. If sufficient placement resources exist, vSAN creates new components on eligible capacity devices and begins resynchronization. After the resync completes, the affected objects transition back to Compliant status. The Repair Delay Timer is primarily associated with absent components, such as a host or device that may return, and is not the required step for a permanent NVMe failure. The administrator does not have to manually trigger Repair Objects Immediately for the normal automatic repair process. A full cluster rebalance is separate from repair and is not performed before rebuilding missing or degraded components.
