Hi

When I do that, and then unmap the lun.

If I then rescan an issue multipath I get:

root@cyrprd1:~# multipath
create: 1                 undef IBM,1726-4xx  FAStT
size=550G features='1 queue_if_no_path' hwhandler='1 rdac' wp=undef
`-+- policy='round-robin 0' prio=0 status=undef
   |- 0:0:0:3 sdd 8:48  undef faulty running
   `- 5:0:0:3 sdl 8:176 undef faulty running
<hang>



Any ideas?

Thanks!

Rudy
