To Check For Zoning Problems; Restoring A Segmented Fabric; To Reconcile Fabric Parameters Individually - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

To check for zoning problems

1. Enter the cfgActvShow command to determine if zoning is enabled.
If zoning is enabled, it is possible that the problem is being caused by zoning enforcement (for
example, two devices in different zones cannot see each other).
2. Confirm that the specific edge devices that need to communicate with each other are in the same zone.
• If they are in the same zone, perform the following tasks:
• Enter the portCamShow command on the host port to verify that the target is present.
• Enter the portCamShow command on the target.
• Enter the nsZoneMember command on the host and target to determine whether or not the
Name Server is aware that these devices are zoned together
• If they are not in the same zone and zoning is enabled, proceed to
3. Resolve zoning conflicts by putting the devices into the same zoning configuration.

Restoring a segmented fabric

Fabric segmentation is generally caused by:
• Incompatible fabric parameters (refer to
• Incorrect PID setting (refer to
• Incompatible zoning configuration (refer to
• Domain ID conflict (refer to
• A switch in a secure fabric is not running Secure Fabric OS.
Refer to the Secure Fabric OS Administrator's Guide for additional information.
There are a number of settings that control the overall behavior and operation of the fabric. Some of these
values, such as the domain ID, are assigned automatically by the fabric and can differ from one switch to
another in the fabric. Other parameters, such as the BB credit, can be changed for specific applications or
operating environments, but must be the same among all switches to allow the formation of a fabric.
The following fabric parameters must be identical for a fabric to merge:
• R_A_TOV
• E_D_TOV
• Data field size
• Sequence level switching
• Disable device probing
• Suppress class F traffic
• Per-frame route priority
• Long distance fabric (not necessary on Bloom-based fabrics)
• BB credit
• PID format

To reconcile fabric parameters individually

1. Log in to one of the segmented switches as admin (switch A).
2. Enter the configShow command.
3. Log in to another switch (switch B) in the same fabric as admin.
4. Enter the configShow command.
5. Compare the two switch configurations line by line and look for differences. Do this by comparing the
two telnet windows or by printing the configShow output. Also verify that the fabric parameter
settings (see
6. Connect to the segmented switch after the discrepancy is identified.
7. Disable the switch by entering the switchDisable command.
