Zone conflicts

ATTENTION

The cfgClear command clears the zoning database on the switch where the command is run.

5. Enter the switchEnable command on each switch once the zoning configuration has been

cleared.

This forces the zones to merge and populates the switches with the correct zoning database.

The fabrics will then merge.

Editing zone configuration members

1. Log in to one of the switches in a segmented fabric as admin.

2. Enter the cfgShow command and print the output.

3. Start another Telnet session and connect to the next fabric as an admin.

4. Enter the cfgShow command and print the output.

5. Compare the two fabric zone configurations line by line and look for an incompatible

configuration.

6. Connect to one of the fabrics.

7. Run zone configure edit commands to edit the fabric zone configuration for the segmented

switch (see Table 13 on page 65 for specific commands.

If the zoneset members between two switches are not listed in the same order in both

configurations, the configurations are considered a mismatch; this results in the switches

being segmented in the fabric.

For example:

[cfg1 = z1; z2] is different from [cfg1 = z2; z1], even though the members of the

configuration are the same.

One simple approach to making sure that the zoneset members are in the same order is to

keep the members in alphabetical order.

Reordering the zone member list

1. Obtain the output from the cfgShow for both switches.

2. Compare the order in which the zone members are listed. Members must be listed in the same

order.

3. Rearrange zone members so the configuration for both switches is the same. Arrange zone

members in alphabetical order, if possible.

Checking for Fibre Channel connectivity problems

Enter the fcPing command (refer to the Fabric OS Command Reference for more information on

this command), which checks the zoning configuration for the two ports specified by:

• Generating an ELS (Extended Link Service frame) ECHO request to the source port

specified and validates the response.
