(resolved) - Long boot time for ESXi hosts even after marking RDM LUNs as perennially-reserved

Long boot time for ESXi hosts even after marking RDM LUNs as perennially-reserved 

 

Error :

2019-09-17T19:47:44.846Z cpu39:65984)WARNING: celerity16fc: Task management abort failed, status:fffffffd
2019-09-17T19:47:44.849Z cpu21:66065)ScsiDeviceIO: 7916: Could not detect setting of QErr for device naa.600507680c8080dca80000000000058a. Error Timeout.
2019-09-17T19:48:02.959Z cpu28:66342)WARNING: ScsiCore: 1806: Invalid sense buffer: error=0x0, valid=0x0

Reason for the issue:

This is due to a known issue with storage stack. Some commands at boot time sense fail with reservation conflicts, timeouts and aborts.

 

Resolution:

At the moment, please try to use vmdk instead of RDM disks and the VMware engineering team looks like they are working on the fix.
