30# DESCRIPTION:
31# Testing Fault Management Agent ZED Logic - Automated Auto-Replace Test.
32#
33# STRATEGY:
34# 1. Update /etc/zfs/vdev_id.conf with scsidebug alias for a persistent path.
35#    This creates keys ID_VDEV and ID_VDEV_PATH and set phys_path="scsidebug".
36# 2. Create a pool and set autoreplace=on (auto-replace is opt-in)
37# 3. Export a pool
38# 4. Wipe and offline the scsi_debug disk
39# 5. Import pool with missing disk
40# 6. Re-online the wiped scsi_debug disk
41# 7. Verify the ZED detects the new unused disk and adds it back to the pool
42#
43# Creates a raidz1 zpool using persistent disk path names
44# (ie not /dev/sdc)
45#
46# Auto-replace is opt in, and matches by phys_path.
