Editing zone configuration members
1.
Log in to one of the switches in a segmented fabric as admin.
2.
Issue the
cfgShow
command and print its output.
3.
Start another telnet session and connect to the next fabric as an administrator.
4.
Issue the
cfgShow
command and print its 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.
Issue zone configure edit commands to edit the fabric zone configuration for the segmented switch
(see
on page 150 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.
Use the output from the
cfgShow
for both switches by comparing the order that the zone members are
listed.
Members must be listed in the same order.
2.
Rearrange zone members so that the configuration for both switches is the same. Arrange zone
members in alphabetical order, if possible.
Recognizing MQ errors
Identify a message queue (MQ) error message by looking for the two letters M and Q in the error
message.
For 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; resolve them by working with the switch supplier. When
MQ errors are encountered, issue the
supportSave
command to capture debug information about the
switch, and then forward the
supportSave
data to the switch supplier for further investigation.
Correcting I
2
C bus errors
I
2
C bus errors indicate defective hardware; the specific item is listed in the error message. See the HP
StorageWorks Fabric OS 5.x diagnostics and system error messages reference guide for information
specific to the error that was received. Some CPT and Environmental Monitor (EM) messages contain
I
2
C-related information.
If the I
2
C message does not indicate the specific hardware that might be failing, begin debugging the
hardware, as this is the most likely cause. The next sections provide procedures for debugging the
hardware.
