advfailover command
This command displays and configures the advanced failover settings for the CMM.
Note
- If a Lenovo Flex System chassis is set up for redundant CMM operation and both CMMs experience an unrecoverable failure, the chassis will attempt to switch control between the CMMs indefinitely. If this condition occurs, replace one CMM to return the chassis to operation or replace both CMMs to return the chassis to redundant operation. Depending on how each CMM failed, you might need to configure the replacement CMM or restore its configuration from a backup, if one is available. A failure of both CMMs might be an indication of other problems with the Lenovo Flex System chassis; make sure that the chassis is operating properly before replacing either CMM. See Troubleshooting chassis for information about diagnosing problems with a Lenovo Flex System chassis.

If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or advfailover command errors for a list of error messages that are specific to the advfailover command.
Function | What it does | Command | Target (see paths in Command targets) |
---|---|---|---|
Display CMM advanced failover settings | Displays the advanced failover settings for the CMM. Possible return values are:
Note When advanced failover is set to off, a | advfailover | Primary CMM:
|
Disable network interface for standby CMM | Disables the network interface for the standby CMM, preventing failover. Note When advanced failover is set to off, a | advfailover -ip off This command can only be run by users who have one or more of the following command authorities:
| Primary CMM:
|
Enable network interface and allow IP address swap during failover | Enables the network interface for the standby CMM and allows the IP addresses to swap between the two CMMs during failover. Note
| advfailover -ip swap This command can only be run by users who have one or more of the following command authorities:
| Primary CMM:
|
Enable network interface and prevent IP address swap during failover | Enables the network interface for the standby CMM and prevents the IP addresses from swapping between the two CMMs during failover. Note The | advfailover -ip noswap This command can only be run by users who have one or more of the following command authorities:
| Primary CMM:
|
Example:
To disable the network interface for the standby CMM, while the primary CMM in bay 1 is set as the persistent command environment, at the system:mm[1]> prompt, type
advfailover -ip off
To display the CMM advanced failover setting, while the primary CMM in bay 1 is set as the persistent command environment, at the system:mm[1]> prompt, type
advfailover
The following example shows the information that is returned from these two commands:
system:mm[1]> advfailover -ip off
OK
system:mm[1]> advfailover
-ip off
system:mm[1]>
