Diagnostics
3-59
A 071 event code indicates the switch is isolated from all switches in
a multiswitch fabric, and is accompanied by a 070 event code for each
segmented E_Port. The 071 event code is resolved when all 070
events are corrected.
Obtain supplementary event data for each 070 event code.
a. At the SANpilot Event Log, examine the first five bytes
(0 through 4) of event data.
b. Byte 0 specifies the switch port number (00 through 11) of the
segmented E_port. Byte 4 specifies the segmentation reason as
specified in Table 3- 12 on page 3-59.
13
A switch E_Port segmented because the error detect time out value
(E_D_TOV) or resource allocation time out value (R_A_TOV) is
incompatible with the attached fabric element.
a. Contact McDATA customer support or engineering personnel to
determine the recommended E_D_TOV and R_A_TOV values
for both switches.
b. Notify the customer both switches will be set offline. Ensure the
system administrator quiesces Fibre Channel frame traffic
through the switches and sets attached devices offline.
c. Set both switches offline. Refer to Set the Switch Online or
Offline on page 4-25.
d. At the View panel, select Configure at the left side of the panel.
The Configure panel opens with the Ports page displayed.
