The system node coredump status command displays status information about core dumps. The command output depends on the parameters specified with the command. If a core dump is in the process of being saved into a core file, the command also displays its name, the total number of blocks that are to be saved, and the current number of blocks that are already saved.

You can specify additional parameters to display only information that matches those parameters. For example, to display coredump status information about the local node, run the command with the parameter -node local .

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.

| [-disks ]

If you specify this parameter, the command displays the following information:

| [-instance ] }

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

If you specify this parameter, the command displays information only about the nodes that have the specified number of complete core dumps that are not yet saved into a core file.

[-partial-disks <integer>] - Number of Disks with Partial Cores

If you specify this parameter, the command displays information only about the nodes that have the specified number of disks with partial core dumps.

[-partial-cores <integer>] - Number of Unsaved Partial Cores

If you specify this parameter, the command displays information only about the nodes that have the specified number of partial core dumps that are not yet saved into a core file.

[-numdisks <integer>] - Total Number of Disks Available for Core Dump

If you specify this parameter, the command displays information only about the nodes that have the specified total number of disks available for core dump.

[-blocks-needed <integer>] - Estimated Number of Blocks Needed for Spray Core

If you specify this parameter, the command displays information only about the nodes that have the specified number of estimated blocks needed for the spray method of dumping core.

[-disks-needed <integer>] - Number of Disks Needed for Spray Core

If you specify this parameter, the command displays information only about the nodes that have the specified number of disks needed for the spray method of dumping core.

[-space-needed {<integer>[KB|MB|GB|TB|PB]}] - Space Needed to Save All Unsaved Cores

If you specify this parameter, the command displays information only about the nodes that require the specified amount of disk space to save all unsaved core dumps.

[-min-free {<integer>[KB|MB|GB|TB|PB]}] - Minimum Free Bytes on Root Filesystem

If you specify this parameter, the command displays information only about the nodes that need to have the specified number of bytes available on the root filesystem after a core dump is saved.
