system node show

Description​

The system node show command displays information about the nodes in a cluster. You can limit output to specific types of information and specific nodes in the cluster, or filter output by specific field values.

To see a list of values that are in use for a particular field, use the -fields parameter of this command with the list of field names you wish to view. Use the system node modify command to change some of the field values that this command displays.

Parameters​

{ [-fields <fieldname>, ...]

If you specify the -fields <fieldname>, ... parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

| [-inventory ]

Use this parameter to display inventory information such as serial numbers, asset tags, system identifiers, and model numbers.

| [-messages ]

Use this parameter to display system messages for each node.

| [-instance ]}

If you specify the -instance parameter, the command displays detailed information about all fields.

[-node {<nodename>|local}] - Node

Selects information for node names that match this parameter value.

[-owner <text>] - Owner

Selects nodes that have owner values that match this parameter value.

[-location <text>] - Location

Selects nodes at specific physical locations that match this parameter value.

[-model <text>] - Model

Selects nodes that have model numbers that match this parameter value.

[-serialnumber <text>] - Serial Number

Selects nodes that have serial numbers that match this parameter value.

[-assettag <text>] - Asset Tag

Selects nodes that have asset tags that match this parameter value.

[-uptime {<seconds>|[<d> days] <hh>:<mm>[:<ss>]}] - Uptime

Selects nodes that have uptimes that match this parameter value. This parameter is most useful when used with a range indicator such as less than or greater than, as in:

          show -uptime >"30 days 00:00"

[-nvramid <nvramid>] - NVRAM System ID

Selects nodes that have NVRAM system IDs that match this parameter value.

[-systemid <text>] - System ID

Selects nodes that have system IDs that match this parameter value.

[-vendor <text>] - Vendor

Selects nodes that have vendor names that match this parameter value.

[-health {true|false}] - Health

Selects nodes that have health values that match this parameter value. Specify true to display healthy nodes, and false to display unhealthy nodes.

[-eligibility {true|false}] - Eligibility

Selects nodes that have voting eligibility values that match this parameter value.

[-epsilon {true|false}] - Epsilon (privilege: advanced)

Selects nodes that have epsilon holding designations that match this parameter value. This is useful to find out which node, if any, in the current cluster has been designated as epsilon. Specify true to display the node holding epsilon, and false to display nodes not holding epsilon.

[-uuid <UUID>] - UUID (privilege: advanced)

Selects nodes that have the specified universal unique identifiers that match this parameter value.

[-is-diff-svcs {true|false}] - Differentiated Services

If true, the corresponding node is considered to be part of differentiated services storage infrastructure.

[-is-all-flash-optimized {true|false}] - All-Flash Optimized

Selects nodes that have "All-Flash Optimized" personality values that match this parameter value. Specify true to display nodes which support only SSD drives, and false to display nodes which support all kinds of drives.

[-is-capacity-optimized {true|false}] - Capacity Optimized

Selects nodes that have "Capacity Optimized" personality values that match this parameter value. Specify true to display nodes which support only SSD drives with Capacity Optimized personality enabled and set false otherwise.

[-is-all-flash-select-optimized {true|false}] - All-Flash Select Optimized

Selects nodes that have "All-Flash Select Optimized" personality values that match this parameter value. Specify true to display nodes which support only SSD drives, and false to display nodes which support all kinds of drives.
