■ Link Incident—Description of the last link incident that occurred on the port.
■ Operational State—Beaconing, inactive, invalid attachment, link incident,
link reset, no light, not operational, online, offline, port failure, segmented
E_Port, testing. See “
Port Operational States ” on page 109 for definitions of
operational states.
■ Reason—Lists the reason for a segmented E_Port, invalid attachment, or
inactive operating state for the port. When an E_Port is segmented, two
fabrics are prevented from joining. An E_Port segmentation only occurs when
the director is connected to another director or a switch. This field displays
“NA” if a segmented E_Port or invalid attachment operating state has not
occurred.
Refer to the section on joining zoned fabrics in the HP StorageWorks SAN
High Availability Planning Manual.
The following messages display in the Reason field of the Port Properties
dialog box if an Invalid Attachment, Segmented E_Port, or Inactive state
occurs for the port. Reason messages for segmentation can include:
— Incompatible operating parameters —Operating
parameters, such as resource allocation time-out values (R_A_TOV) or
error-detect time-out values (E_D_TOV), are inconsistent on connected
switches. See “
Configuring Fabric Parameters ” on page 122 for more
information.
— Duplicate domain IDs —Identical preferred domain IDs are
configured for two or more directors or switches. See “ Configuring Fabric
Parameters ” on page 122 for more information.
— Incompatible zoning configurations —Refer to the HP
StorageWorks HA-Fabric SAN High Availability Planning Guide for
information on joining zoned fabrics.
— Build fabric protocol error .
— No principal switch —A principle switch is not defined for the
fabric.
— No response from the attached switch.
A Port Binding error may be due to an invalid WWN or nickname entry in the
Configure Ports dialog box in the Bound WWN column. See “
Configuring
Ports ” on page 132 for a description of the Configure Ports dialog box.
Reason messages for an invalid attachment can include:
— 0x0C ESA Security Mismatch —Security features do not match.
