To list all IP addresses that cannot be automatically discovered when using Dynamic Host Configuration Protocol (DHCP):
lssysconn -r nondiscover [-F [attribute-names] [--header]]
[--help]
To list Virtualization Management Interface (VMI) network interface information for an Enterprise Baseboard Management Controller (BMC) based managed system:
lssysconn -r vmi -m managed-system
[-F [attribute-names] [--header]] [--help]
lssysconn also lists IP addresses that cannot be automatically discovered by this HMC when using DHCP. If this HMC is set up as a DHCP server on a private network, whenever the Remove Connection task or the rmsysconn command is run to remove a managed system from the HMC, the HMC places the IP address(es) of that system in a list of removed IP addresses. Any IP address in that list will not be rediscovered when reattached to the HMC. The lssysconn -r nondiscover command can be used to display the contents of that list of removed IP addresses.
lssysconn also lists VMI network interface information for an Enterprise BMC-based managed system.
| -r | The type of resources for which to list connection information. Valid values are all for all managed systems, nondiscover for all IP addresses that cannot be automatically discovered by this HMC when using DHCP, and vmi for VMI network interface information for an Enterprise BMC-based managed system. |
| -m | The name of the Enterprise BMC-based managed system for which to list VMI network interface information. 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. |
| -F |
A delimiter separated list of attribute names for the desired attribute values to be displayed for each resource. If no attribute names are specified, then values for all of the attributes for each resource will be displayed.
When this option is specified, only attribute values will be displayed. No attribute names will be displayed. The attribute values displayed will be separated by the delimiter which was specified with this option. This option is useful when only attribute values are desired to be displayed, or when the values of only selected attributes are desired to be displayed. |
| --header | Display a header record, which is a delimiter separated list of attribute names for the attribute values that will be displayed. This header record will be the first record displayed. This option is only valid when used with the -F option. |
| --help | Display the help text for this command and exit. |
lssysconn -r all
List only the IP address and connection state for all of the systems managed by this HMC, and separate the output values with a colon:
lssysconn -r all -F ipaddr:state
List all IP addresses that cannot be automatically discovered by this HMC when using DHCP:
lssysconn -r nondiscover
List VMI network interface information for the Enterprise BMC-based managed system ebmcSys:
lssysconn -r vmi -m ebmcSys
