The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes how to set up remote management in your startup configuration for use in recovering an unreachable Cisco Nexus Virtual Services Appliance and includes the following sections:
You can add remote management to your redundant Cisco Nexus Virtual Services Appliance startup configuration so that in the event one of the pair becomes unreachable, the other can automatically attempt to recover it.
If redundant Cisco Nexus Virtual Services Appliances cannot communicate with each other over the management and control interfaces, they can both become active simultaneously. This is known as a split-brain conflict. A Cisco Nexus Virtual Services Appliance cannot be rebooted from its peer switch using high availability.
If one of the Cisco Nexus Virtual Services Appliances becomes unreachable, its peer becomes active if it was standby. If you have configured remote management, the newly-active Cisco Nexus Virtual Services Appliance can attempt to power cycle its unreachable peer switch through the mgmt0 port of its CIMC interface if CIMC is reachable on the peer. The active Cisco Nexus Virtual Services Appliance starts the reboot code immediately when the standby is lost. The standby Cisco Nexus Virtual Services Appliance waits 60 seconds before starting the reboot code.
For more information about loss of communication between redundant Cisco Nexus Virtual Services Appliances, see the Cisco Nexus 1000V High Availability and Redundancy Configuration Guide, Release 4.2(1)SV1(5.1) .
For more information about CIMC, see the “Cisco Integrated Management Controller” section.
You can use this procedure to set up remote management in the startup configuration to be used in recovering an unreachable Cisco Nexus Virtual Services Appliance peer switch through the mgmt0 port of its CIMC software.
Before beginning this procedure, you must know or do the following:
2. nexus1010-system remote-mgmt primary ip ipaddr username username password password
3. nexus1010-system remote-mgmt secondary ip ipaddr username username password password
