7. Verify the zone groups for each of the host using the smp_discover_list command.
a) Issue the following command to locate the expander handles:
ls /dev/bsg

b) Issue the following command to access a single host's SMP Discover output:
smp_discover_list /dev/bsg/expander-9:39
c) Zone group 9 can be identified by the
ZG:9
located at the end of each line in zone 9. The above example
displays PHYs 0-13 as being in zone group 9. All other devices are labeled as
inaccessible
because
the host is displaying the only devices it has access to. The step can be repeated on other hosts to see
what zone group each host has access to.
d) Issue the following command to access all hosts smp_discover_list:
smp_discover_list --ignore /dev/bsg/expander-9:39
e) Zone group 9, 10, 11, 12, 13, and 14 can be identified by the
ZG
located at the end of each group in
each of their respective zones. The above example displays PHYs 0-13 as being in zone group 9, PHYs
14-27 as being in zone group 10, and so on.
