Configuring the switch
84
Following are some examples of principal switch selections when switches have these settings:
•
If you have three switches and set all to Default, the switch with the lowest WWN becomes
the principal switch.
•
If you have three switches and set two to Principal and one to Default, the switch with the
Principal setting that has the lowest WWN becomes the principal switch.
•
If you have three switches and set two to Default and one to Never Principal, the switch
with the Default setting and the lowest WWN becomes the principal switch.
Note that at least one switch in a multiswitch fabric needs to be set as Principal or Default. If all
of the switches are set to Never Principal, all of the interswitch links (ISLs) will segment. If all but
one switch is set to Never Principal and the switch that was Principal goes offline, then all of
the other ISLs will segment.
NOTE:
HP recommends configuring switch priority as Default. If you are considering changing
this value to something other than the default, refer to sections on principal switch selection for
multiswitch fabrics in the HP StorageWorks SAN high availability planning guide
for details.
In the audit log you may notice that the Principal setting maps to a number code of 1, Default
maps to a number code of 254, and Never Principal maps to a number code of 255. The
number codes 2-253 are no longer in use.

•
Open Fabric 1.0—Default. Choose this mode if the fabric contains HP directors and
switches, as well as other open-fabric compliant switches. Choose this mode for managing
heterogeneous fabrics.
