Fabric Assist Mode Telnet Commands
WWNs are specified as eight hex numbers separated by colons, for example
"10:00:00:60:69:00:00:8a". Zoning has no knowledge of the fields
within a WWN; the eight bytes are simply compared with the Node and Port
Names presented by a device in a login frame (FLOGI or PLOGI).
When a Fabric Assist zone member is specified by Node Name, then all ports on
that device are in the Fabric Assist zone. When a Fabric Assist zone member is
specified by Port Name, only that single device port is in the Fabric Assist zone.
Zone alias names have the same format as Fabric Assist zone names and are
created with the aliCreate command. The alias must resolve to a list of one or
more physical fabric port numbers, WWNs, or a Fabric Assist host.
A Fabric Assist host member is defined by wrapping the physical fabric port or a
physical device (a WWN) between "H{" and "}". For example, "H{5,6}" or
"H{10:00:00:60:69:00:00:8a}" is a Fabric Assist host. The type of
Fabric Assist zone members used to define a Fabric Assist zone may be mixed and
matched.
For example, a Fabric Assist zone defined with the following members
"2,12; 2,14; 10:00:00:60:69:00:00:8a" would contain devices
connected to switch 2, ports 12 and 14, and the device with a WWN of
"10:00:00:60:69:00:00:8a" (either Node Name or Port Name -
whichever port in the fabric it is connected to.)
Each target listed within the fazone definition is assigned an ALPA when the
private hosts performs loop initialization. When the private host communicates
with this assigned ALPA, the private loop frame is translated into a public format
and then delivered to the target's location within the fabric.
Loop devices that are zoned with the private host are assigned the same ALPA
claimed during their own loop initialization, provided that it is still available on
the private host's loop. Other public devices zoned with the private host is
assigned the lowest available ALPA during the private host's loop initialization.
However, if the ALPA by which the fazoned target is identified, does not conform
to the default ALPA assignment process, then a preferred ALPA is assigned to
each target within the fazone definition. The identified preferred ALPA is the
ALPA value that is assigned to the target during the privates host's loop
initialization, provided that it is not claimed by the private host or another
preferred ALPA assignment.
To assign a preferred ALPA, add the definition of the target (Domain, Port or
WWN) and the preferred ALPA within square brackets [ ]. For example, a fazone
defined with the following members:
48
"H{1,1}; 2,12[0xe2]; 2,14[0xe8];10:00:00:60:69:00:00:8a[0xef}"
