David Teigland	d952358636	device_id: nvme devices may use alternate wwids ... Device quirks may cause sysfs wwid file to change what it displays, from a bogus eui... string to an nvme... string. The old wwid may be saved in system.devices, so recognizing the device requires finding the old value from libnvme. After matching the old bogus value using libnvme, system.devices is updated with the current sysfs wwid value.	2024-12-09 16:03:43 -06:00

David Teigland	228a8e8c1f	device_id: ignore leading and trailing spaces for sys_wwid and sys_serial ... Leading and trailing underscores are also ignored to handle device ids written by previous versions which replaced all spaces with underscores.	2023-06-15 15:17:14 -05:00
David Teigland	dc99f0def1	device_id: ignore quotes in device id ... A t10 wwid string was found containing a " character which breaks vg metadata parsing. Ignore any quotation marks in device id strings.	2023-02-06 12:24:18 -06:00

David Teigland	bdab36cf3f	device_id: look for serial number in other locations ... Only /sys/dev/block/major:minor/device/serial was read to find a disk serial number, but a serial number seems to be reported more often in other locations, so check these also: /sys/dev/block/major:minor/device/vpd_pg80 /sys/class/block/vda/serial (for virtio disks only)	2022-11-07 08:56:02 -06:00
David Teigland	380ab3f45c	device id wwid adjustments ... Move the functions handling dev wwids. Add dev flags indicating that wwids have been read from sysfs wwid file or sysfs vpd_pg83 file. This can be used to avoid rereading these. Improve filter-mpath search for a device's wwid in /etc/multipath/wwids, to avoid unnecessary rereading of wwids from sysfs files. Type 8 wwids from vpd_pg83 with naa or eui names should be saved as those types.	2022-10-10 11:47:29 -05:00
David Teigland	3b0f9cec7e	filter-mpath: get wwids from sysfs vpd_pg83 ... to compare with wwids in /etc/multipath/wwids when excluding multipath components. The wwid printed from the sysfs wwid file may not be the wwid used in multipath wwids. Save the wwids found for each device on dev->wwids to avoid repeating reading and parsing the sysfs files.	2022-06-08 15:06:01 -05:00
