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
