Obtaining Failover Status Information

Use the showfailover(1M) command on the main SSP to display failover status information. The following example shows the failover information displayed.

ssp% showfailover  
Failover State:
     SSP Failover: Disabled
     CB Failover:  Active
Failover Connection Map:
     Main SSP to Spare SSP thru Main Hub:   FAILED
     Main SSP to Spare SSP thru Spare Hub:  FAILED
     Main SSP to Primary Control Board:     GOOD
     Main SSP to Spare Control Board:       GOOD
     Spare SSP to Main SSP thru Main Hub:   FAILED
     Spare SSP to Main SSP thru Spare Hub:  FAILED
     Spare SSP to Primary Control Board:    FAILED
     Spare SSP to Spare Control Board:      FAILED
SSP/CB Host Information
     Main SSP:                              xf12-ssp
     Spare SSP:                             xf12-ssp2
     Primary Control Board (JTAG source):   xf12-cb1
     Spare Control Board:                   xf12-cb0
     System Clock source:                   xf12-cb1

The failover status includes the

• Failover state

  The failover state is one of the following:

  • Active -- automatic failover is enabled and functioning normally

  • Disabled -- automatic failover has been disabled by operator request or by a failure condition that prevents a failover from occurring

  • Failed -- a failover occurred

    After a failover, the status is listed as Failed until you re-enable failover using the setfailover(1M) command. You must manually re-enable failover, even after you have fixed all connections and they are identified as GOOD in the failover connection map (explained below).

• Failover connection map

  The connection map provides the status of the control board connection links monitored by the failover processes. A connection link is either GOOD, which means the connection is functioning properly, or FAILED, which indicates the connection is not working.

  If you have failed connections, use this connection map to help determine the failure condition. For additional details on the failure conditions associated with the various failure points, see "Description of Failover Detection Points" in Chapter 10, SSP Internals.

• SSP/CB host information

  The host information identifies the SSPs, control boards, and the control board that manages the JTAG interface and system clock.

You can also obtain information about the role of the current SSP by specifying the showfailover(1M) command with the -r option. The SSP role is either UNKNOWN (SSP role has not been determined), MAIN, or SPARE.

For additional details on the showfailover(1M) command, see the showfailover(1M) man page.
