edge switch 2/16 service manual B–7
Event Codes
Event Code: 070
Message: E_Port is segmented.
Severity: Informational.
Explanatio
n:
A switch E_Port recognized an incompatibility with an attached fabric element (director
or switch), preventing the switch from participating in the fabric. A segmented port does
not transmit Class 2 or Class 3 traffic (data from attached devices), but transmits Class
F traffic (management and control data from the attached director or switch). Refer to
the event data for the segmentation reason.
Action: Action depends on the segmentation reason specified in the event data.
Event
Data:
The first byte of event data (byte 0) specifies the E_Port number. The fifth byte (byte 4)
specifies the segmentation reason as follows:
1 = Incompatible operating parameters. Ether the resource allocation time out value
(R_A_TOV) or error detect time out value (E_D_TOV) is inconsistent between the
switch and another fabric element (director or switch). Modify the R_A_TOV and
E_D_TOV to make the values consistent for all fabric directors and switches.
2 = Duplicate domain ID. The switch has the same preferred domain ID as another
fabric element (director or switch). Modify the switch’s Domain ID to make it unique.
3 = Incompatible zoning configurations. The same name is applied to a zone for the
switch and another fabric element (director or switch), but the zones contain different
zone members. Modify the zone name to make it unique, or ensure zones with the same
name contain identical zone members.
4 = Build fabric protocol error. A protocol error was detected during incorporation of
the switch into the fabric. Disconnect the E_Port link, reconnect the link, and initial
program load (IPL) the switch. If the condition persists, perform the data collection
procedure and return the Zip disk to Hewlett Packard support personnel.
5 = No principal switch. No director or switch in the fabric can become the principal
switch. Modify the switch priority to any value other than 255.
6 = No response from attached switch (hello timeout). The switch periodically
verifies operation of attached fabric elements (directors or switches). The switch E_Port
(at the operational switch) times out and segments if the attached device does not
respond. Check the status of the attached director or switch. If the condition persists,
perform the data collection procedure (at the attached device) and return the Zip disk to
Hewlett Packard support personnel.
7 = ELP retransmission failure timeout. A switch that exhibits a hardware or link
failure attempted to join a fabric and transmitted multiple exchange link protocol (ELP)
frames to a fabric element (director or switch). However, because of the problem, the
switch did not receive responses to the ELP frames, and did not receive a fabric login
(FLOGI) frame. After five ELP transmission attempts, the switch E_Port (failed switch)
times out and segments. Refer to MAP 0000: Start MAP to perform hardware fault
isolation at the failed switch.
