Configuring RPM Redundancy
To select a primary RPM, use the following command. The RPM in slot 0 is the primary RPM by default.
• Manually select the primary RPM.
CONFIGURATION mode
redundancy primary
Example of Viewing RPM Redundancy Configuration
Dell#show running-config redundancy
!
redundancy auto-failover-limit count 3 period 60
redundancy auto-synchronize full
redundancy primary rpm0
Dell#
To view which RPM is the primary, use the show running-config redundancy command from EXEC
Privilege mode, as shown in the example in the Forcing an RPM Failover.
Forcing an RPM Failover
To force an RPM failover, use the following command.
Use this feature when you are replacing an RPM and when you are performing a warm upgrade.
• To trigger an RPM failover between RPMs.
EXEC Privilege mode
redundancy force-failover rpm
Example of the redundancy force-failover rpm Command
Dell#redundancy force-failover rpm
Peer RPM's SW version is different but HA compatible.
Failover can be done by warm or hitless upgrade.
All linecards will be reset during warm upgrade.
Specify hitless upgrade or warm upgrade [confirm hitless/warm]:hitless
Proceed with warm upgrade [confirm yes/no]:
Specifying an Auto-Failover Limit
When a non-recoverable fatal error is detected, an automatic failover occurs.
However, Dell Networking OS is configured to auto-failover only three times within any 60 minute
period. You may specify a different auto-failover count.
To re-enable the auto-failover-limit with its default parameters, use the redundancy auto-failover-
limit command without parameters.
• Set a different auto-failover count.
CONFIGURATION mode
redundancy auto-failover-limit
• Re-Enable the auto-failover-limit with its default parameters.
