We have an incident where after upgrading our Supermciro to the latest 6.5 ESXi release where ESXi is not seeing the internal SAS drives.
Internal SAS controller is not seeing the drives.
Prior to the ESXi update, vCenter was showing under Storage Adapters, MegaRAID SAS Invader Controller with Storage Device Local AVAGO disk.
I booted the ESXi server and went into the RAID utility.
All of the drives show on-line and active with no failures.
I checked with the vendor and we tried a new backplane riser card.
Did not help. He said if the drives are seen by the controller, then he thinks the problem is not a hardware issue.
He thinks there is some disconnect in the ESXi somewhere …especially since the only two hardware pieces it could be at this point are backplane and motherboard.
However, the internal SATA drives are working fine, so that really rules out the backplane and motherboard.
Has anyone seen anything like this after upgrading ESXi 6.5?
Anyone see something similar?
