HP Brocade 4Gb SAN Switch for HP BladeSystem p-Class - Manual (Page 189)

Fabric OS 5.0.0 procedures user guide 189
To verify a fabric merge problem:
1. Issue the
switchshow
command to validate that the segmentation is due to a zone issue.
2. See Table 30 on page 187 to view the different types of zone discrepancies.
To edit zone configuration members:
1. Log in to one of the switches in a segmented fabric as admin.
2. Issue the
cfgshow
command.
Typing the asterisk
*
after the command displays list of all configuration names.
3. Print the output from the
cfgShow
command.
4. Start another telnet session and connect to the next fabric as an administrator.
5. Issue the
cfgShow
command.
6. Print the output from the
cfgShow
command.
7. Compare the two fabric zone configurations line by line and look for an incompatible configuration.
8. Connect to one of the fabrics.
9. Issue zone configure edit commands to edit the fabric zone configuration for the segmented switch
(see Table 31 on page 188 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.
To reorder the zone member list:
1. Use the output from the
cfgshow
for both switches.
2. Compare the order that the zone members are listed. Members must be listed in the same order.
3. Rearrange zone members so that the configuration for both switches is the same. Arrange zone
members in alphabetical order, if possible.
Recognizing MQ-WRITE errors
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 SNS 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 supplier. When MQ errors are encountered, execute the
supportsave
command to capture
debug information about the switch; then forward the
supportsave
data to the switch supplier for
further investigation.
