Device Aliases
You can define device aliases without specifying the
VSAN number. You can also use the same definition
in one or more VSANs without any restrictions.
Device aliases can be used with any feature that uses
the pWWN.
Only pWWNs are supported.
Device aliases are not restricted to zoning. Device
alias configuration is available to the FCNS, zone,
fcping, and traceroute applications.
