Zoning examples

The following zoning examples describe ways for zoning a switch. In the examples, a list of port names that are inside brackets ([]) represent a single zone whose zone members are the list of ports shown.

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.
  • Two hosts that are called P and Q.
  • Each of the two hosts has two ports, as described in the following table.
    Table 1. Two hosts and their ports
    P Q
    P0 Q0
    P1 Q1
  • Two switches that are called X and Y.
  • Two storage systems I and J.
  • Each of the two storage systems has ports as described in the following table.
    Table 2. Two storage systems and their ports
    I J
    I0 J0
    I1 J1
    I2  
    I3  
The following tasks comprise an example configuration:
  1. Attach half the host and node ports 1 (A0, A1, B0, B1, P0, Q0) to switch X.
  2. Attach half the host and node ports 3 (A2, A3, B2, B3, P1, Q1) to switch Y.
  3. Attach half the storage system ports (I0, I1, J0) to switch X.
  4. Attach half the storage system ports (I2, I3, J1) to switch Y.
  5. Create one zone per host port (one port per node) on switch X:
    • [A0, B0, P0]
    • [A1, B1, Q0]

    An example of a host zone illustrates this example.

  6. Create one storage zone per storage system on switch X:
    • [A0, A1, B0, B1, I0, I1]
    • [A0, A1, B0, B1, J0]

    An example of a storage system zone illustrates this example.

  7. Create one internode zone on switch X:
    • [A0, A1, B0, B1]

    An example of a system zone illustrates this example.

  8. Follow the same steps #svc_zoningaswitch_22n6zd/switchctrrpeat through #svc_zoningaswitch_22n6zd/switchxinter to create the following list of zones for switch Y:
    One zone per host port:
    • [A2, B2, P1]
    • [A3, B3, Q1]
    Storage zone:
    • [A2, A3, B2, B3, I2, I3]
    • [A2, A3, B2, B3, J1]
    One internode zone:
    • [A2, A3, B2, B3]

Example 2

The following example describes a SAN environment that is like the previous example except for the addition of four hosts that have two ports each.
  • Two nodes that are 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 that are 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 the following table.
    Table 3. 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 that are called X and Y.
  • Three storage systems
  • Each storage system has ports as described in the following table.
    Table 4. Three storage systems and their ports
    I J K
    I0 J0 K0
    I1 J1 K1
    I2   K2
    I3   K3
        K4
        K5
        K6
        K7

The following tasks comprise a different example configuration:

  1. Attach half of the host and node ports 1 (A0, A1, B0, B1, P0, P1, Q0, Q1, R0, R1, S0, S1, T0, U0) to switch X.
  2. Attach half of the host and node ports 1 (A2, A3, B2, B3, P2, P3, Q2, Q3, R2, R3, S2, S3, T1, U1) to switch Y.
  3. Attach half of the storage system ports (I0, I1, J0, K0, K1, K2, K3) to switch X.
  4. Attach half of the storage system ports (I2, I3, J1, K4, K5, K6, K7) to switch Y.
  5. Create one zone per host port (one port per node) on switch X:
    • [A0, B0, P0]
    • [A1, B1, P1]
    • [A0, B0, Q0]
    • [A1, B1, Q1]
    • [A0, B0, R0]
    • [A1, B1, R1]
    • [A0, B0, S0]
    • [A1, B1, S1]
    • [A0, B0, T0]
    • [A1, B1, U0]
    Attention: Hosts T and U (T0 and U0) and (T1 and U1) are zoned to different ports so that each port is zoned to the same number of host ports.
  6. Create one storage zone per storage system on switch X:
    • [A0, A1, B0, B1, I0, I1]
    • [A0, A1, B0, B1, J0]
    • [A0, A1, B0, B1, K0, K1, K2, K3]
  7. Create one internode zone on switch X:
    • [A0, A1, B0, B1]
  8. Follow the same steps #svc_zoningaswitch_22n6zd/onezoneswitchx through #svc_zoningaswitch_22n6zd/internodex to create the following list of zones for switch Y:
    One zone per host port:
    • [A2, B2, P2]
    • [A3, B3, P3]
    • [A2, B2, Q2]
    • [A3, B3, Q3]
    • [A2, B2, R2]
    • [A3, B3, R3]
    • [A2, B2, S2]
    • [A3, B3, S3]
    • [A2, B2, T1]
    • [A3, B3, U1]
    Storage zone:
    • [A2, A3, B2, B3, I2, I3]
    • [A2, A3, B2, B3, J1]
    • [A2, A3, B2, B3, K4, K5, K6, K7]
    One internode zone:
    • [A2, A3, B2, B3]
