  • Core segment file name

  • Node that owns the core segment file

  • System ID of the node that generated the core

  • MD5 checksum of the compressed data of the core segment file

  • Name of the core segment

  • Total number of core segments for the core file

  • Timestamp of the panic that triggered the core segment

[-node {<nodename>|local}] - Node

Selects information about the core segments on the specified node.

[-segment <text>] - Core Segment

Selects information about the specified core segment. If segment is a directory, the command displays the information for the first core segment file. If segment is a file, the command displays the file information.

[-owner-node <text>] - Node That Owns the Core Segment File

Selects information about the core segments owned by the specified node. This parameter should only be used in takeover mode to display information about the partner's core segments.

[-panic-system-id <integer>] - System ID of Node That Generated Core

Selects information about the core segments that were generated when the node with the specified system ID panicked.

[-md5-data-chksum <text>] - Md5 Checksum of the Compressed Data of the Core Segment

Selects information about the core segments whose data segment's MD5 checksum matches the specified checksum.

[-segment-name <text>] - Name of the Core Segment

Selects information about the core segments with the specified name.

[-total-segment-count <integer>] - Number of Segments Generated

Selects information about the core segments with the specified name.

[-panic-time <MM/DD/YYYY HH:MM:SS>] - Time of Panic That Generated Core

Selects information about the core segments that were generated by a panic at the specified time.

[-size <text>] - Size of Core Segment (bytes)

Selects information about the core segments that are of the specified size.

[-panic-string <text>] - Panic String of Panic That Generated Core

Selects information about the core segments that match the specified panic string.
