6.2.3.8 lscelldisk

List cell disks.

Purpose

The lscelldisk command displays information about Exadata storage server cell disks in the Exascale cluster.

Syntax

lscelldisk [ celldisk [ celldisk ]... ] [ -l ] [ --detail ] 
           [ --attributes attribute[,attribute]... ] 
           [ --filter filter[,filter]... ] 
           [ --sort [-]attribute[,[-]attribute]... ] 
           [ --count value ]

Command Options

The options for the lscelldisk command are:

  • celldisk: Identifies an Exadata cell disk that you want to list information about. If not specified, the command displays information about all cell disks.

  • -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 celldisks 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.

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
