Issue/Introduction

How to clean up after RDM device recovered from PDL on ESXi.

Environment

ESXi 8.0.x

Cause

Storage issue caused PDL for RDM device.

Need to recover those device after the storage recovered.

Resolution

To clean up an unplanned PDL:

  • Power off the relevant VMs
  • Verify the process of the VM is gone
    esxcli vm process list
  • Restart Management Agents (If needed): If the PDL state persists, or if hostd (the main host management daemon) is behaving erratically, a restart can clear the kernel's reference.

/etc/init.d/hostd restart
/etc/init.d/vpxa restart

  • Rescan All from UI or cli :

esxcli storage core adapter rescan --all 

  • In rare cases, especially when the device is still stuck in a persistent Dead state despite the LUN being available, a reboot of the ESXi host may be required to clear the kernel's persistent memory of the PDL state.
    • Place Host in Maintenance Mode.
    • Reboot the Host.
    • Exit Maintenance Mode and verify the RDM is fully functional.
