From f0020e428af7c7a705a264be21a67b1c89574af0 Mon Sep 17 00:00:00 2001 From: Dick Kennedy Date: Tue, 30 Jun 2020 14:49:58 -0700 Subject: scsi: lpfc: Add support to display if adapter dumps are available Currently, if there has been an issue whereby an adapter dump was taken, there is nothing displayed to hint that it is present. Utilities must be run and they must query for the status in order to then download the dump. Add a message to the driver to query dump image presence when initializing the SLI Port.
