Problema


Environment
Host model:  ProLiant BL460c Gen8
ESXi  VMware ESXi 6.0.0 build-10719132
HBA  QLogic Corp 2600 Series 16Gb Fibre Channel to PCI Express HBA
HBA driver  2.1.73.0-1OEM.600.0.0.2768847 
PowerPath/VE  6.x
Unity 450F Software 4.3.1.1525703027

Symptoms:
When hosts were running VMware ESXi 6.0.0 build-6921384 (or earlier) Unity LUNs were not erroring.

Causa
Cause (from VMware driver team):
There is a change in ESXi 6.0 EP15 compared with ESXi 6.0 P06: In case H:0xc error is reported, we will retry the command at driver layer instead of HBA layer.
This was done to avoid adapter queue full conditions.
 
Resolución

Install the HBA driver  2.1.81.0 (or above) and firmware  8.08 (or above) as per VMware HCL
