2-32 edge switch 2/32 installation guide
Installing and Configuring the Edge Switch 2/32
• 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.
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: We recommend you leave the switch priority setting as Default. If you are considering
setting this value to something other than default, refer to the section on principal switch
selection for multiswitch fabrics in the HP StorageWorks Products in a SAN Environment
—
Planning Manual for details.
In, for example, 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 of 2 — 253 are not currently in use.
