File _service:tar_scm_kernel_repo:0007-rescan-scsi-bus.sh-add-option-no-lip-scan.patch of Package sg3_utils
From b109bf4c5bacf65d32d2ab4fb990efb5230fda27 Mon Sep 17 00:00:00 2001 From: Douglas Gilbert <dgilbert@interlog.com> Date: Fri, 12 Aug 2022 02:55:43 +0000 Subject: [PATCH] rescan-scsi-bus.sh: add option --no-lip-scan lip is a FC operation and can be used to rescan device but it can not specify the channel and target. So add a new option to scan FC hosts according to the SCSI general interface in sysfs: /sys/class/scsi_host/hostX/scan. The default value of no_lip_scan is 0 which does not change the default behavior.
