Failover command, bigpipe

From RZWiki

A CLI command available on F5 BigIP platforms; used to configure failover settings and modify or display failover status for a device configured in a High Availability (HA) pair or cluster.

Usage Syntax

bigpipe failover [options]

The four available status related options are;

• standby - forces an active device to assume the standby role
• failback - restores an active/active configuration after a device failure
• online - forces an offline cluster to assume the active or standby role
• offline - forces an online (and therefore active or standby) cluster to go offline

Usage Examples

bigpipe failover - display current failover status

bigpipe failover standby - force device to assume the standby role

Usage Notes

The failover part of this command can be abbreviated to fo.

No output is given when this command successfully forces the device into the standby role.

In most cases you should not need to use this command as failover and (optional and not recommended by this author) failback occur automatically.

Additionally, failover status is shown as part of the command prompt text.

Typical Output

noinclude/noinclude

[user@test:Active] ~ # b failover
FAILOVER active for 29 days 05:45:56

[user@test:Active] ~ # b failover standby

[user@test:Standby] ~ # b failover
FAILOVER standby for 00:00:07

Bigpipe Usage Notes

font color=redFrom v9.4, be aware of the administrative partition that is currently active;/font use the bigpipe shell partition command to display the current active partition name and the bigpipe shell partition name command to change partitions.

A full command manual can be displayed using the man command followed by the command name, for example: man pool or by suffixing the command name with the help keyword, for example; bigpipe pool help.

In most cases, the font color=purpleshow/font keyword displays object status or statistics and the font color=purplelist/font keyword displays configuration. URemember/U, from v9.4, only objects in the currently active administrative partition will be displayed.

The bigpipe command can be abbreviated to just b (e.g. b help instead of bigpipe help.) Alternatively, (from v9.4,) you can use the bigpipe shell to enter commands without prefixing them with bigpipe.

Where curly or normal brackets {}' or () or quotes ' or exclamation mark ! are required as part of a command and you are not using the bigpipe shell, they must be proceeded with a back slash \ to prevent the BASH shell from parsing them as system commands.
