Tony Hutter 7e56b05058 Better zfs_get_enclosure_sysfs_path() enclosure support ... A multpathed disk will have several 'underlying' paths to the disk. For example, multipath disk 'dm-0' may be made up of paths: /dev/{sda,sdb,sdc,sdd}. On many enclosures those underlying sysfs paths will have a symlink back to their enclosure device entry (like 'enclosure_device0/slot1'). This is used by the statechange-led.sh script to set/clear the fault LED for a disk, and by 'zpool status -c'. However, on some enclosures, those underlying paths may not all have symlinks back to the enclosure device. Maybe only two out of four of them might. This patch updates zfs_get_enclosure_sysfs_path() to favor returning paths that have symlinks back to their enclosure devices, rather than just returning the first path.
