director 2/64 service manual 3–19
Repair Information
Zone members display as:
• The unique 16-digit WWN identifying the device attached to the port. If a
nickname is configured, the nickname displays instead. For example:
10:00:02:06:77:43:B0:1C
• A unique domain ID (1 through 31 inclusive) and port number (0 through 63
inclusive) if zoned by port number. For example:
Domain 1, Port 7
The information is also useful to maintenance personnel for fault isolating E_Port
segmentation problems caused by incompatible zone sets.
When forming a multiswitch fabric by connecting directors with active zone sets, zone
names within the active zone sets should not be duplicated. Zone names can be
duplicated only if the member WWNs of each zone are identical. If two directors have
a zone name conflict (duplicate zone names exist), the zone sets cannot merge, the
connecting E_Port at each director segments to prevent the creation of an ISL, and the
directors do not form a multiswitch fabric.
• For a description of how to expand or collapse the active zone set list, and an
explanation of button functions at the bottom of the Zone Set View, refer to the hp
StorageWorks ha-fabric manager user guide.
Performing Port Diagnostics
Port and UPM card diagnostics are performed at the director or HAFM server
(Product Manager application). These diagnostics include:
• Inspecting port and UPM card LEDs at the director.
• Obtaining port degradation or failure information at the Product Manager
application’s Port Card View.
• Obtaining statistical performance information for ports at the Product Manager
application’s Performance View.
• Performing internal or external port loopback tests.
• Performing channel wrap tests. The tests apply only to a director configured for
S/390 operating mode.
