116 Edge Switch 2/24 Service Manual

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.

1. At the Hardware View, click Logs > Event Log. The Event Log displays.

2. Examine the first five bytes (0 through 4) of event data.

3. Byte 0 specifies the switch port number (00 through 23) of the segmented

E_port. Byte 4 specifies the segmentation reason as specified in Table 19.

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.

1. Contact HP support to determine the recommended E_D_TOV and

R_A_TOV values for both switches.

2. 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.

3. Set both switches offline. Refer to “Set the Switch Online or Offline” on

page 174.

4. At the Hardware View for the first switch reporting the problem, click

Configure > Operating Parameters > Fabric Parameters. The Configure

Fabric Parameters dialog box displays (Figure 30).
