TSM notification
TSM notification. See Compaq TSM notification.
TSM Notification Director Application. See Compaq TSM Notification Director
Application.
TSM package. See Compaq TSM package.
TSM server software. See Compaq TSM server software.
TSM Service Application. See Compaq TSM Service Application.
TSM workstation. See Compaq TSM workstation.
two-lane link. The two single-mode fiber-optic (SMF) ServerNet cables that connect the HP
NonStop™ Cluster Switches on the same external fabric (for example, X1, X2, and X3)
in a tri-star topology.
UCME. See uncorrectable memory error (UCME).
UID. A nonnegative integer that uniquely identifies a user within a node.
In the Open System Services (OSS) environment, the UID is the scalar view of the HP
NonStop™ Kernel user ID. The UID is used in the OSS environment for functions
normally associated with a UNIX user ID.
unattended site. A computer environment where there is no operator residing on site and
the only access is from a central monitoring station.
uncorrectable memory error (UCME). An error caused by incorrect data at a particular
memory location. The cause of the error is such that the error is not automatically
corrected by the system, and memory replacement is required. Contrast with
correctable memory error (CME).
undefined. Pertaining to the use of an incorrect value for data or the incorrect behavior of a
program for which the ISO/IEC IS 9945-1:1990 standard imposes no portability
requirements.
undervoltage. A negative change in the amplitude of the voltage.
uninterruptible power supply (UPS). The equipment used to provide an uninterruptible
source of power to connected equipment if a main power outage occurs. The basic
components of any UPS system are a rectifier/charger that converts alternating-current
(AC) power to direct-current (DC) power, batteries that store the DC power, and an
inverter that converts the DC power back into AC power for distribution to the load.
unmount. In the Network File System (NFS), to make a fileset inaccessible to the users of a
node.
