SEGMENTS Command

The SEGMENTS command lists all the defined segment names and the segment type

(data) of each segment.

SQL Command

Do not use the SQL command.

STATUS Command

Use the STATUS command to list the current ownership status of a segment or

segments. The status of a segment is an indication of its current ownership, rather

than an indication of the accessibility of its member volumes.

SEGMENT { segname | * }

indicates which segments are affected by the STATUS command. You can specify

the volumes in a specific segment (segname) or all volumes in all segments (*).

If you do not include the SEGMENT parameter, the volumes in the current

segment are affected. Each segment usually has four paths defined, although

some segments might have only one or two.

Considerations

Each path in a segment definition has a switch card associated with it. Each path also

has a switch setting definition, indicating ownership. The STATUS command

interrogates the current switch setting of each switch card associated with the segment

and reports one of the following results:

•

OWNED

If all the current switch settings for the segment match the defined ownership

settings, the segment is considered OWNED by this node.

•

NOT OWNED

If all the current switch settings are opposite of the defined ownership settings, the

segment is considered NOT OWNED by this node.
