lssystem

Use the lssystem command to display a detailed view of a clustered system (system).

Syntax

lssystem [ -nohdr ] [ -delim delimiter ]

Parameters

-nohdr: (Optional) By default, headings are displayed for each item of data in a detailed style view. The -nohdr parameter suppresses the display of these headings.
Note: If no data exists to be displayed, headings are not displayed.
-delim delimiter: (Optional) In a detailed view, each item of data has its own row, and if the headers are displayed, the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a character with 1 byte. In a detailed view, the data is separated from its header by the specified delimiter.

Description

This command displays a detailed view of a system.

lssystem output provides the attribute values that can be displayed as output view data.

Table 1. lssystem output

deduplication_opportunity	Indicates the total amount of `used_capacity_before_reduction` of all volume-copies within data reduction pools that are enabled for data deduplicatoin.

Information about the remote system is reported by the lssystem command if you issue either the mkfcpartnership or mkippartnership command from the local system to the remote system. For example, if the partnership is at least partially established from the local system.

Issue the lssystem command to display a detailed view of the system.

Detailed view shows the fields that are described for remote systems only; if the system location is local, then partnership and bandwidth do not apply (and are not defined or provided). For a remote system, these fields indicate the following information:

location: remote or local
partnership
fully_configured: The mkfcpartnership or mkippartnership command is issued in both directions and the remote system is online and available.
partially_configured_local: The mkfcpartnership or mkippartnership command is issued from the local system to the remote system. The remote system is online and available for partnership.
partially_configured_local_stopped: The mkfcpartnership or mkippartnership command is issued from the local system to the remote system. The chpartnership command with the stop parameter is issued from the local system, and the remote system is online and available. Issue the chpartnership command with the start parameter on the local system, and mkfcpartnership or mkippartnership on the remote system.
not_present: The mkfcpartnership or mkippartnership command is issued from the local system to the remote system, and the remote system is not available. Either the remote system is offline, or it is not connected to the local system.
fully_configured_stopped: The mkfcpartnership or mkippartnership command is issued in both directions and the remote system is online and available. The chpartnership command with the stop parameter is issued from the local system.
fully_configured_remote_stopped: The mkfcpartnership or mkippartnership command is issued in both directions and the remote system is online and available. The chpartnership command with the stop parameter is issued from the remote system.
fully_configured_local_excluded: The mkfcpartnership or mkippartnership command is issued in both directions. The local system is excluding the connection to the remote system due to too many problems, or either system in the partnership is unable to sustain the I/O workload for the Metro Mirror, Global Mirror, or HyperSwap relationships.; The mkfcpartnership or mkippartnership command is issued in both directions. The local system is excluding the connection to the remote system due to too many problems.
fully_configured_remote_excluded: The mkfcpartnership or mkippartnership command has been issued in both directions. The remote system is excluding the connection to the local system due to too many problems, or either system in the partnership is unable to sustain the I/O workload for the Metro Mirror, Global Mirror, or HyperSwap relationships.; The mkfcpartnership or mkippartnership command is issued in both directions. The remote system excludes the connection to the local system due to too many problems.
fully_configured_exceeded: Too many systems exist in the system network, and the partnership from the local system to the remote is disabled. Refer to the 1710 or 1720 errors in the system error log at the local and remote system.
bandwidth: The bandwidth available on the intersystem link for background copy, in megabytes per second (MBps).
Important: For partnerships over IP links with compression, this parameter specifies the aggregate bandwidth after the compression had been applied to the data. Do not set this parameter higher than the physical link bandwidth multiplied by the (carefully rounded down) compression factor.

The console_IP field displays either the:

Automatically populated system port 1 IP Address - Internet Protocol Version 4 (IPv4) or IPv6
User-populated IPv4 address

The port value is always 443, which requires the system to run by using default Hypertext Transfer Protocol Secure (HTTPS).
