9. Compare the two fabric zone configurations line by line and look for

incompatible configuration. See “

Fabric Merge Conflicts Related to Zoning

on page 207 for definitions.

10. Log into one of the Fabrics.

11. Run zone configure edit commands to edit the fabric zone configuration for

the segmented switch. Refer to the

HP StorageWorks Zoning Version

3.1.x/4.1.x User Guide

for specific commands.

Reorder the Zone Member List

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.

12. Use the output from the

cfgshow

for both switches.

13. Compare the order that the zone members are listed. Members must be listed

in the same order.

14. Rearrange zone members so that the configuration for both switches is the

same. Arrange zone members in alphabetical order, if possible.

15. Continue to the next step if all zone members appear to be the same and are

displayed in the same order.

MQ-WRITE Error

An MQ error is a message queue error. Identify an MQ error message by looking
for the two letters M and Q in the error message.

Example:

MQ errors can result in devices dropping from the Simple Name Server or can
prevent a switch from joining the fabric. MQ errors are rare and difficult to
troubleshoot, and it is suggested that they be resolved by working with the switch
