Admin Domains and switch WWN
Admin Domains are treated as fabrics. Because switches cannot belong to more than one fabric, switch
WWNs are converted so that they appear as unique entities in different Admin Domains (fabrics). This
WWN conversion is done only in the AD1 through AD254 context. AD0 and AD255 use unconverted
switch WWNs.
The switch WWN is in the following format:
10:00:
nn
:
nn
:
nn
:
nn
:
nn
:
nn
In an Admin Domain context, the switch WWN is converted from NAA=1 to NAA=5 format, with the
Admin Domain number added, using the following syntax:
5
n
:
nn
:
nn
:
nn
:
nn
:
nn
:
n
9:
xx
where
xx
is the AdminDomain_number.
For example, if the switch WWN is:
10:00:00:60:69:e4:24:e0
then the converted WWN for that switch in AD1 would be:
50:06:06:9e:42:4e:09:01
Figure 6 shows an unfiltered view of a fabric with two switches, three devices, and two Admin Domains.
The devices are labeled with device WWN and the switches are labeled with domain ID and switch
WWN.

Figure 7 shows the filtered view of the fabric as seen from AD3 and AD4. The switch WWNs are
converted to the NAA=5 syntax; the device WWNs and domain IDs remain the same.
AD4
WWN = 10:00:00:00:c8:3a:fe:a2
AD3
WWN = 10:00:00:00:c2:37:2b:a3
Domain ID = 2
WWN = 10:00:00:05:2e:06:34:6e
Domain ID = 1
WWN = 10:00:00:05:1f:05:23:6f
WWN = 10:00:00:00:c7:2b:fd:a3
