Servo power interrupt

service safety doorA motor-driven barrier that separates the service areas of the customer interface module from the rest of the library so that service personnel can safely repair or replace failed library mechanisms while the library continues normal operations. Synonymous with safety barrier.

A signal that removes voltage to a motor if overtravel is detected in the motor or a safety condition exists (for example, the main access door to the library storage module is open). When the sensor or switch is made, the drive current to the motor disables and an error posts. The SPI prevents a servo runaway condition for an out-of-range motor; it also prevents motors from starting up while the access door is open.

SL8500 addressA five-digit, comma-separated value (L,C,R,S,W) that represents Library, Rail, Column, Side, and Row. This addressing scheme is used by SL8500 firmware and internal communications to represent all devices and locations within the library.

SL8500 drive bayA two-digit integer

(01–64) that represents the physical locations into which drive tray assemblies are inserted.

slotThe location in the library in which a cartridge is stored. Synonymous with cell.

standby (pass-thru port)The side of a pass-thru port (PTP) that operates in response to actions initiated by the master side of the PTP. See also master (pass-thru port).

storage expansion

moduleAn optional module for the Product Name library that provides up to 1728 additional cartridge storage slots. Up to three modules can be attached to each SL8500 library.

Storage Management

Component (SMC)The software interface between IBM’s OS/390 and z/OS operating systems and StorageTek real and virtual hardware. SMC performs the allocation processing, message handling, and SMS processing for the NCS solution. It resides on the MVS host system with HSC and/or MVS/CSC, and communicates with these products to determine policies, volume locations, and drive ownership. SMC is a required NCS component.
