STATUS Command

•

UNKNOWN

For any other permutation of switch settings, the ownership of the segment is

considered UNKNOWN. Although UNKNOWN is not necessarily bad, it is an

exception condition. A segment might be owned by the interrogating node, but a

switch module, for some reason, might not be accessible. In this case, the setting

of the switch cards in that switch module cannot be determined, and the status

would be reported as UNKNOWN.

The volumes in the segment might be accessible in spite of the inaccessibility of

the switch module. A switch card is passive; it does not need power to pass the

signals through to the disk module. It does, however, need power to respond to

STATUS and SWITCH instructions.
