Hi,

I recently did some raw mappings on my esxi. Now esxi is now acting strangely by showing some disks as dead whereas they are not (checked that by removing these disks and testing in other system.

Please advise howto do a sanity check/remove loose ends.

If you have "mapped RAW disks" to local disks this is an un-supported feature of the Hypervisor, and "anything can happen".

VMware will not support this function, as the product is being used beyond it's design specification.

It's possible that the drive paths have changed, been altered, and the path to that original mapped disk is no longer available and hence a dead path.

I would check the /var/log/vmkernel.log on the ESXi server, and check it it's complaining about claim paths not found, or dead paths.

Then I won t use raw mappings anymore. Performance was much lower then expected .  Running Synology on hp NL 40 is my solution. It has support for ssd cache so I can (not tried yet) use the ssd s in the sharkoon and thus optimize speed.
