David Bond	e92a3d8fa3	udev: 60-persistent-storage-tape.rules: handle duplicate device ID ... Some SCSI tape devices use the same device ID (NAA registered device designator) for the SCSI tape changer device and the first actual tape device. For example, this one: https://docs.oracle.com/en/storage/tape-storage/storagetek-sl150-modular-tape-library/slofs/bridged-tape-drives.html You must connect the bridged drive to an HBA supporting multiple LUNs (also referred to as LUN scanning). The SL150 Library uses a single SCSI ID and two logical unit numbers (LUN). LUN 0 controls the tape drive and LUN 1 which is configured as a SCSI medium changer device controls the robotics. Data is sent to the remaining LUN on the bridged drive or to LUNs on the other, unbridged drives in the partition, all of which are configured as SCSI sequential-access (tape) devices. This may lead to errors because /dev/tape/by-id symlinks may sometimes point to the st device representing the tape, and sometimes to the sg device representing the changer. Fix this by assigning an increased priority to the tape device, and creating a separate -changer link for the SCSI tape changer.

Zbigniew Jędrzejewski-Szmek	ef2ad30aee	Rename udev's rules/ to rules.d/ ... This change is only about the source tree. We have tmpfiles.d/, modprobe.d/, sysctl.d/, and sysusers.d/, but for historical reasons, rules/ didn't fit this pattern. We also *install* it as rules.d/. Let's rename to be consistent.	2019-10-10 00:53:09 +01:00
