After updating Emulex drivers to either version 12.8.317.0 or 12.8.351.29 on ESXi 6.5 or 6.7, users report loss of connection to their arrays.


Emulex driver versions 12.8.317.0 and 12.8.351.29 for ESXi 6.5 and 6.7 are setting writeXferRdyDis irrespective of lpfc_first_burst_enable parameter. Dell Storage rejecting PRLI because B_WR_XFR_RDY_DISABLE is enabled.


The user can choose from one of the following fixes:
  1. A fix from Emulex is in the Emulex version 12.8.542.25 and later driver for ESXi 6.7. This driver is now available on and is expected to be added to an upcoming Dell Customized ESXi 6.7 OS image.
  2. A fix from Dell EMC is in 5978.479 and 5978.711 code to accept the PRLI minus the bits we do not support. This fix allows the initiators with Emulex HBAs to log in successfully regardless of which versions of the Emulex or Broadcom driver and firmware are loaded. This fix is expected in an upcoming code release. Customers with ESXi 6.5 must use this fix from Dell EMC or upgrade to ESXi 6.7 to use the Emulex version 12.8.542.25 or later driver.
