Last updated on APRIL 08, 2021

Applies to:

Solaris Operating System - Version 11.3 and later
Emulex FC HBA - Version All Versions and later
Information in this document applies to any platform.

Symptoms

In SR-IOV mode, when one VF is reset or its link is brought down, it
affects the other VFs as well - the work queue entry (WQE) is locally
rejected with link down error.

In a LDOM configuration there are multiple domains configured using SR-IOV.

  06:09:18 ldm start ld2m
  06:10:58 ldm start ld3m
  06:11:00 ldm start ld4m
  06:11:02 ldm start ld5m

On one older LDOM (ld1m), the customer is getting the following error when
any of the domains above are rebooted (they are booted from network)
