I got around that some time ago with a little hack;
Maintain a directory with soft links to disks of interest:
ls -l .../mydsklist
total 50
lrwxrwxrwx 1 cx158393 staff 17 Apr 29 2006 c1t0d0s1 ->
/dev/dsk/c1t0d0s1
lrwxrwxrwx 1 cx158393 staff 18 Apr 29 2006 c1t16d0s1 ->
/dev/dsk/c1t16d0s1
lrwxrwxrwx 1 cx158393 staff 18 Apr 29 2006 c1t17d0s1 ->
/dev/dsk/c1t17d0s1
Then:
zpool import -d ..../mydkslist mypool
Hope that helps...
