Oracle Solaris ZFS Administration Guide

Importing ZFS Storage Pools From Alternate Directories

By default, the zpool import command only searches devices within the /dev/dsk directory. If devices exist in another directory, or you are using pools backed by files, you must use the -d option to search alternate directories. For example:

# zpool create dozer mirror /file/a /file/b
# zpool export dozer
# zpool import -d /file
  pool: dozer
    id: 7318163511366751416
 state: ONLINE
action: The pool can be imported using its name or numeric identifier.

        dozer        ONLINE
          mirror-0   ONLINE
            /file/a  ONLINE
            /file/b  ONLINE
# zpool import -d /file dozer

If devices exist in multiple directories, you can specify multiple -d options.
