From: James Smart Date: Tue, 12 Apr 2022 22:19:47 +0000 (-0700) Subject: scsi: lpfc: Requeue SCSI I/O to upper layer when fw reports link down X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b6474465e962369c1cd4b00324c2e175e2cf30cf;p=linux.git scsi: lpfc: Requeue SCSI I/O to upper layer when fw reports link down During heavy I/O stress tests with 100+ vports and cable pulls, it may take a while before the vport logs back into the fabric to resume I/O. Currently, the driver immediately fails the I/O with DID_ERROR. Change behavior to return DID_REQUEUE, and rely on SCSI layer's max retry of 5 before erroring out the I/O.
