If your HMC is set up as a DHCP server on a private network, you should not use this command to remove HMC connections to managed systems. The remove option of this command is intended for use on a public network only, where the HMC is not set up as a DHCP server. Using the remove option of this command prevents the HMC from managing any system at that IP address, even though that address may still be assigned through DHCP.
If your HMC is set up as a DHCP server on a private network and you do use this command to remove a connection, the HMC places the IP address(es) of the managed system being removed, or places the IP address being removed, in a list of removed IP addresses. Any IP address in that list will not be automatically rediscovered by the HMC. If you want to remove an IP address from that list so that the IP address can be automatically discovered and the HMC can manage a system at that IP address in the future, use the rediscover option of this command. If you want to remove all IP addresses from that list, you can use the mksysconn -o auto command.
| -o |
The operation to perform. Valid values are remove, reset, or rediscover.
When remove is specified, the HMC disconnects from the specified managed system. If all connections to the managed system are removed, then the managed system is removed from the HMC. When reset is specified, the HMC disconnects from the specified managed system then attempts to reconnect. The reset operation is useful for retrying to establish a connection to a managed system that is in the "No Connection" state. When rediscover is specified, the specified IP address is removed from the HMC’s list of removed IP addresses. This will allow the HMC to automatically reconnect to that IP address when using DHCP. |
| -m |
The name of the managed system to remove or to reset the connection to. The name may either be the user-defined name for the managed system, or be in the form tttt-mmm*sssssss, where tttt is the machine type, mmm is the model, and sssssss is the serial number of the managed system. The tttt-mmm*sssssss form must be used if there are multiple managed systems with the same user-defined name.
If the managed system has a single service processor, the connection to the service processor is removed or reset. When the connection is removed, the managed system is removed from the HMC. If the managed system has two service processors, the connections to both service processors for the managed system are removed or reset. When the connections to both service processors for the managed system are removed, the managed system is removed from the HMC. To remove or reset the connection to just one service processor for the managed system, use the --ip option. Either this option or the --ip option is required for a remove or a reset operation. This option is not valid for a rediscover operation. The -m and --ip options are mutually exclusive. |
| --ip |
To remove or reset the connection to a managed system with a single service processor, you can use this option to specify the IP address or host name of the service processor for the managed system to remove or to reset the connection to. Alternatively, you can use the -m option to specify the name of the managed system to remove or to reset the connection to.
To remove or reset the connection to just one service processor for a managed system with two service processors, you can use this option to specify the IP address or host name of the service processor to remove or to reset the connection to. To remove or reset the connection to both service processors for a managed system, use the -m option. Note that a managed system with two service processors will not be removed from the HMC until the connections to both service processors for the managed system are removed. To allow the HMC to automatically rediscover an IP address when using DHCP, use this option to specify the IP address to be automatically rediscovered. Either this option or the -m option is required for a remove or reset operation. This option is required for a rediscover operation. The --ip and -m options are mutually exclusive. |

rmsysconn -o remove -m mySys
Reset the connection to the managed system service processor with IP address 9.3.152.145:
rmsysconn -o reset --ip 9.3.152.145
Allow the IP address 10.0.0.127 to be automatically rediscovered when using DHCP:
rmsysconn -o rediscover --ip 10.0.0.127
