Requirements for hardware-assisted takeover
The hardware-assisted takeover feature is available only on systems with an RLM or SP module configured for remote management. Remote management provides remote platform management capabilities, including remote access, monitoring, troubleshooting, logging, and alerting features.
Although a system with remote management on both nodes provides hardware-assisted takeover for both, hardware-assisted takeover is also supported on HA pair s in which only one of the two systems has remote management configured. Remote management does not have to be configured on both nodes in the HA pair . Remote management can detect failures on the system in which it is installed and provide faster takeover times if a failure occurs on the system with remote management.
See the Data ONTAP 7-Mode System Administration Guide for information about setting up remote management.
