Unable to change Remote Management Module (RMM) settings on Gen4S Avamar nodes. The ipmitool commands fail reporting "LAN Parameter Data does not match! Write may have failed." For example: ipmitool lan set 3 ipaddr 0.0.0.0 Setting LAN IP Address to 0.0.0.0 LAN Parameter Data does not match! Write may have failed.
The error "LAN Parameter Data does not match! Write may have failed." occurs due to a prohibited write or change of the IPMI/BMC parameters. The prohibition applied when in Section "[LANCHANNELS]" the parameter LANFailOver equals enable. To be able to change network settings of IPMI, this parameter should be set to be disabled to perform the change, then reenabled.

Configure RMM as required:(Substitute the values appropriate for the environment) ipmitool lan set 3 ipaddr <IP-Address> ipmitool lan set 3 netmask <Subnet-Mask> ipmitool lan set 3 defgw ipaddr <Gateway) Example commands and output using IP Address 10.1.23.221, Subnet 255.255.255.0, and gateway 10.1.23.1: ipmitool lan set 3 ipaddr 10.1.23.221 Setting LAN IP Address to 10.1.23.221 ipmitool lan set 3 netmask 255.255.255.0 Setting LAN Subnet Mask to 255.255.255.0 ipmitool lan set 3 defgw ipaddr 10.1.23.1 Setting LAN Default Gateway IP to 10.1.23.1 3.
