Valid values for partitions using dedicated processors are keep_idle_procs, share_idle_procs, share_idle_procs_active, share_idle_procs_always.

Valid values for partitions using shared processors are capped, uncapped.

mem (optional, int, None)

The value of dedicated memory value in megabytes to create a partition.

timeout (optional, int, None)

The maximum time, in minutes, to wait for partition operating system to complete dlpar.

This option is valid for following actions update_proc_mem, update_pv, update_npiv and update_vod

pv_settings (optional, list, None)

List of Physical Volumes settings to be configured.

This option is valid only for update_pv action.

disk_name (True, str, None)

Name of the Disk.

vios_name (True, str, None)

Virtual IO Server name of the Disk belongs to.

target_name (optional, str, None)

Target Device name.

Optional, if not provided auto assigns <vtscsi*>.

server_adapter_id (optional, int, None)

The Server adapter slot number to be configured with SCSI adapter.

Optional, if not provided next available value will be assigned.

client_adapter_id (optional, int, None)

The client adapter slot number to be configured with SCSI adapter.

Optional, if not provided next available value will be assigned.

npiv_settings (optional, list, None)

List of Virtual Fibre Channel port settings to be configured.

This option is valid only for update_npiv action.

fc_port_name (True, str, None)

Fibre Channel Port name.

vios_name (True, str, None)

Virtual IO Server name of the Fibre Channel Port belongs to.

wwpn_pair (optional, str, None)

The WWPN pair value to be configured with client FC adapter.

Both the WWPN value should be separated by semicolon delimiter example ‘c0507607577aefc0;c0507607577aefc1’.

Optional, if not provided the value will be auto assigned.

server_adapter_id (optional, int, None)

The Server adapter slot number to be configured with FC adapter.

Optional, if not provided next available value will be assigned.

client_adapter_id (optional, int, None)

The client adapter slot number to be configured with FC adapter.

Optional, if not provided next available value will be assigned.

vod_settings (optional, list, None)

List of Virtual optical device settings to be configured.

This option is valid only for update_vod action.

device_name (True, str, None)

Name of the device.

vios_name (True, str, None)

Virtual IO Server name.

server_adapter_id (optional, int, None)

The Server adapter slot number to be configured.

Optional, if not provided next available value will be assigned.

client_adapter_id (optional, int, None)

The client adapter slot number to be configured.

Optional, if not provided next available value will be assigned.

media_name (optional, str, None)

Name of the media to be loaded.

Optional, if not provided no media will be loaded.

action (True, str, None)

update_proc_mem updates the processor and memory resources of the partition.

update_pv Attach Physical Volumes via Virtual SCSI.

update_npiv Attach FC Port.

update_vod Attach Virtual Optical Device.

Notes

Note

• If the updating of settings for at least one VIOS is successful during the execution of the “update_pv” action, the changed status will be displayed as 1, and any failed updates will be shown as warnings. This behavior remains consistent for both the “update_npiv” and “update_vod” actions.

• Passwordless authentication is not supported
