Export ID_WWN_VENDOR_EXTENSION and ID_WWN_WITH_EXTENSION
Some SCSI devices use the same WWN and have a WWN extension that we need to take into account when creating the /dev/disk/by-id/wwn symlinks. Thus, introduce ID_WWN_WITH_EXTENSION. This property will contain either the WWN (if no extension is present) or the WWN with the vendor extension appended. Example: # /lib/udev/ata_id/ata_id --export /dev/sda |grep WWN ID_WWN=0x5001517387d61905 ID_WWN_WITH_EXTENSION=0x5001517387d61905 # /lib/udev/scsi_id --whitelisted --export -d /dev/sdb |grep WWN ID_WWN=0x600508b400105df7 ID_WWN_VENDOR_EXTENSION=0x0000e00000d80000 ID_WWN_WITH_EXTENSION=0x600508b400105df70000e00000d80000 # /lib/udev/scsi_id --whitelisted --export -d /dev/sdc |grep WWN ID_WWN=0x600508b400105df7 ID_WWN_VENDOR_EXTENSION=0x0000e00000db0000 ID_WWN_WITH_EXTENSION=0x600508b400105df70000e00000db0000 Signed-off-by: David Zeuthen <davidz@redhat.com>
