Compaq TSM package. A software product for NonStop S-series servers that provides the
information needed to perform functions such as querying resources and testing,

TMDS, Syshealth, and Remote Maintenance Interface (RMI) on earlier NonStop
systems.

ring subnetwork for the specified ServerNet/FX adapter. You need to use the

DISCONNECT command.
CPU stuck. A state in which a processor in a cluster on a FOX ring loses all four FOX direct
logical paths (XL, XR, YL, and YR) to a processor in another cluster on the FOX ring.
CPU stuck is not a state of the processor itself. See also Path down.
