Subject: [PATCH] rescan-scsi-bus.sh: use LUN wildcard in idlist
Message-Id: <20181025084911.19958-1-mwilck () suse ! com>
X-MARC-Message: https://marc.info/?l=linux-scsi&m=154045737232713
By scanning for LUN 0 only, we may encounter a device that the
kernel won't add (e.g. peripheral device type 31) and which may
thus never appear in sysfs for us to use for REPORT LUNS. That
causes LUN additions for such devices to be missed by
"rescan-iscsi-bus.sh -a".
