Configuration Utility Program (COUP)

Configuration Utility Program (COUP). A utility used in D-series and earlier RVUs to

make online changes to the configuration of devices and controllers. COUP is part of

the Dynamic System Configuration (DSC) facility. In G-series RVUs, COUP functions

are performed by the Subsystem Control Facility (SCF).

Subsystem Control Facility (SCF) STATUS or INFO command when you use the

direct connect. Connection from the FCSA to the ESS without going through an FC switch.

disk bootstrap. A software entity residing on disk that is used to load the HP NonStop

operating system image (OSIMAGE) into memory during a system load of a NonStop

S-series server. A disk that contains the disk bootstrap is referred to as a bootable

disk. The disk bootstrap is placed on the disk either as part of a tape load or as a result

of the SCF CONTROL DISK, REPLACEBOOT command.

On a Integrity NonStop NS-series server, the bootstrap program is installed through

firmware update into flash memory.

disk cache. A temporary storage buffer into which data is read, retained, and perhaps

updated before being written to disk, for more efficient processing.

disk drive. A device that stores and accesses data on a disk. Random access to

addressable locations on a magnetic disk is provided by magnetic read/write heads.
