Environment

ESXi 7.x
ESXi 8.x 

 

Cause

A corruption in datastore/partition usually reports these events of duplicate names and it can be observed in hostd, vmkernel, vmkwarning log.

Resolution

Attempt a VOMA fix. Reach out to Broadcom support for assistance Creating and managing Broadcom support cases.

If the corruption is on the OSDATA partition, then the solution is to reinstall the ESXi hosts. Refer to OSDATA volume has been detected corrupted.
