NAME

 showfailover - display system controller (SC) failover status or role

SYNOPSIS

 showfailover [-r] [-v]
 showfailover -h

DESCRIPTION

 

showfailover(1M) enables you to monitor the state of the SC failover mechanism. This command displays the current status of the failover mechanisms. If you do not specify a -r option, then the following information is displayed:
 
SC Failover Status: state

The failover mechanism can be in one of four states: ACTIVATING, ACTIVE, DISABLED, or FAILED. See the EXTENDED DESCRIPTION section.

OPTIONS

 

The following options are supported:

-h
Help. Displays usage descriptions. Note – Use alone. Any option specified in addition to -h is ignored.
-r
Displays the SC's role as either MAIN, SPARE, or UNKNOWN.
-v
Verbose. Displays all available command information.

EXTENDED DESCRIPTION

 

The failover mechanism states are as follows:

ACTIVATING
Indicates that the failover mechanism is preparing to transition to the ACTIVE state. Failover becomes active when all tests have passed and files have been synchronized.
ACTIVE
Indicates that the failover mechanism is enabled and is functioning normally.
DISABLED
Indicates that the failover mechanism has been disabled due to a failover or an operator request (for example, setfailover off).
FAILED
Indicates that the failover mechanism has detected a failure that prevents a failover.

In addition, if the external network has been configured, showfailover displays the state of each of the external network interface links monitored by the failover processes. The display format is as follows:

external community name: [UP|DOWN]

A failure string is returned, describing the failure condition. Each failure string has a code associated with it. The codes and associated failure strings are defined in the following table.

StringExplanation
NoneNo failure.
S-SC EXT NETThe spare SC external network interface has failed.
S-SC CONSOLE BUS A fault has been detected on the spare SC's console bus path.
S-SC LOC CLKThe spare SC's local clock has failed.
S-SC DISK FULLThe spare SC's system is full.
S-SC IS DOWN The spare SC is down and/or unresponsive. If this message results from the I2 network/HASRAMs being down then the spare SC could still be running. Login to the spare SC to verify.
S-SC MEM EXHAUSTEDThe spare SC's memory/swap space has been exhausted.
S-SC SMS DAEMONAt least one SMS daemon could not be started/restarted on the spare SC.
S-SC INCOMPATIBLE SMS VERSIONThe spare SC is running a different version of SMS software. Both SCs must be running the same version.
I2 NETWORK/HASRAMS DOWNBoth interfaces for communication between the SCs are down. The main cannot tell what version of SMS is running on the spare nor what its state is. It declares the spare SC down and logs a message to that effect. Dependent services, including file propagation, are unavailable.

Group Privileges Required

 

You must have platform administrator, platform operator, or platform service privileges to run this command.
