The command “hmc resetsysconn” can be used to reset a connection between HMC and managed system. The HMC first closes the connection to the specified managed system and then tries to reconnect the managed system. This can be useful if a connection has the status “No Connection“.

The argument can be either the IP address:

$ hmc resetsysconn hmc02 192.168.240.7
$

or the managed system:

$ hmc resetsysconn hmc02 ms11
$

If a managed system has more than one service processor and the managed system is specified as an argument, the connections to both service processors are reset. If an IP address is specified, only the connection to the service processor with the specified IP address is reset.
