6.2.3.9 lscluster

List cluster information.

Purpose

The lscluster command displays information about the Exascale cluster.

Syntax

lscluster [ -l ] [ --detail ] [ --attributes attribute[,attribute]... ] 
          [ --filter filter[,filter]... ] 
          [ --sort [-]attribute[,[-]attribute]... ] 
          [ --count value ] [ --backup ]

Command Options

The options for the lscluster command are:

• -l: Displays output in a long, tabular format.

• --detail: Displays detailed output with additional attributes.

• --attributes: Identifies specific attributes to display in the output.

  To see a list of all available attributes and their descriptions, use the describe clusters command. See also Describing Resources and Attributes.

• --filter: Specifies conditions for including items in the output.

• --sort: Sorts the output using the specified attributes.

• --count: Specifies the maximum number of items to display in the output.

• --backup: Limits the output to list only volume backup attributes.

Usage Notes

Note the following information when using this command:

• Filter conditions are specified as: <attribute><operator><value>.

  The allowed operators are =, !=, >=, <=, >, and <.

  Multiple comma-separated filter conditions are combined using AND logic.

  Dates can be specified using the following formats:

  • yyyy-MM-dd''T''HH:mm:ss
  • yyyy-MM-dd (Time is assumed to be 00:00 AM)
  • HH:mm:ss (Date is assumed to be today)

  A date can also be followed by a timezone specification.

  Sizes can be specified using suffixes K, KB, M, MB, G, GB, T, TB. The suffix is not case-sensitive.

  For example, the following filter only includes objects created after 9 AM today:

  --filter createTime>9:00:00

• Sorting attributes are specified as: [-]attribute. Multiple sort attributes are comma-delimited. The default sort order is ascending. For descending sort order, prefix the attribute name with -.

  For example, use the following to primarily sort by name in descending order, and use creation time in ascending order to further sort entries with the same name:

  --sort -name,createTime
