Zoning examples

These examples describe ways for zoning a switch.

Example 1

Consider the SAN environment in the following example:

Two nodes (nodes A and B)
Nodes A and B each have four ports
- Node A has ports A0, A1, A2, and A3
- Node B has ports B0, B1, B2, and B3
Four hosts called P, Q, R, and S
Each of the four hosts has two ports, as described in Table 1.
Table 1. Four hosts and their ports
P Q R S

P0 Q0 R0 S0

P1 Q1 R1 S1
Two switches called X and Y
One storage controller
The storage controller has four ports on it called I0, I1, I2, and I3

Table 1. Four hosts and their ports
P	Q	R	S
P0	Q0	R0	S0
P1	Q1	R1	S1

The following is an example configuration:

1. Attach ports 1 (A0, B0, P0, Q0, R0, and S0) and 2 (A1, B1, P1, Q1, R1, and S1) 
   of each node and host to switch X.
2. Attach ports 3 (A2, B2, P2, Q2, R2, and S2) and 4 (A3, B3, P3, Q3, R3, and S3) 
   of each node and host to switch Y.
3. Attach ports 1 and 2 (I0 and I1) of the storage controller to switch X. 
4. Attach ports 3 and 4 (I2 and I3) of the storage controller to switch Y.

Create the following host zones on switch X:

5. Create one zone per host port (one port per node) (A0, B0, P0, A0, B0, and Q0)
6. Create one zone per host port (one port per node) (A0, B0, R0, A0, B0, and S0)

Create the following host zones on switch Y:

7. Create a host zone on switch Y containing ports 3
   (A2, B2, P2, Q2, R2, and S2) of each node and host.
8. Create a host zone on switch Y containing ports 4
   (A3, B3, P3, Q3, R3, and S3) of each node and host.

Create the following storage zone:

9. Create a storage zone that is configured on each switch. 
   Each storage zone contains all the SAN Volume Controller and
   storage ports on that switch.

Example 2

The following example describes a SAN environment that is similar to the previous example except for the addition of two hosts that have two ports each.

Two nodes called A and B
Nodes A and B have four ports each
- Node A has ports A0, A1, A2, and A3
- Node B has ports B0, B1, B2, and B3
Six hosts called P, Q, R, S, T and U
Four hosts have four ports each and the other two hosts have two ports each as described in Table 2.
Table 2. Six hosts and their ports
P Q R S T U

P0 Q0 R0 S0 T0 U0

P1 Q1 R1 S1 T1 U1

P2 Q2 R2 S2 — —

P3 Q3 R3 S3 — —
Two switches called X and Y
One storage controller
The storage controller has four ports on it called I0, I1, I2, and I3

Table 2. Six hosts and their ports
P	Q	R	S	T	U
P0	Q0	R0	S0	T0	U0
P1	Q1	R1	S1	T1	U1
P2	Q2	R2	S2	—	—
P3	Q3	R3	S3	—	—

The following is an example configuration:

1. Attach ports 1 (A0, B0, P0, Q0, R0, S0 and T0) and 2 
   (A1, B1, P1, Q1, R1, S1 and T0) of each node and host to switch X.
2. Attach ports 3 (A2, B2, P2, Q2, R2, S2 and T1) and 4 
   (A3, B3, P3, Q3, R3, S3 and T1) of each node and host to switch Y.
3. Attach ports 1 and 2 (I0 and I1) of the storage controller to switch X. 
4. Attach ports 3 and 4 (I2 and I3) of the storage controller to switch Y.

Attention: Hosts T and U (T0 and U0) and (T1 and U1) are zoned to different SAN Volume Controller ports so that each SAN Volume Controller port is zoned to the same number of host ports.

Create the following host zones on switch X:

5. Create a host zone containing ports 1 (A0, B0, P0, Q0, R0, S0 and T0) of each 
   node and host.
6. Create a host zone containing ports 2 (A1, B1, P1, Q1, R1, S1 and U0) of each 
   node and host.

Create the following host zones on switch Y:

7. Create a host zone on switch Y containing ports 3 
   (A2, B2, P2, Q2, R2, S2 and T1) of each node and host.
8. Create a host zone on switch Y containing ports 4
    (A3, B3, P3, Q3, R3, S3 and U1) of each node and host.

Create the following storage zone:

9.  Create a storage zone configured on each switch.
Each storage zone contains all the SAN Volume Controller
and storage ports on that switch.
