I/O multifunction (IOMF) CRU
I/O multifunction (IOMF) CRU. (1) A NonStop S-series server customer-replaceable unit
(CRU) that connects the I/O enclosure to a processor enclosure, using a ServerNet
cable, and that supplies power to the components within the IOMF CRU, as well as
redundantly to the disk drives, SCSI terminators, and ServerNet adapters in that
enclosure. The IOMF CRU contains a power supply, a service processor, a ServerNet
router, an Ethernet controller, an external ServerNet port, and three SCSI ServerNet
addressable controllers (SACs) in a single unit. (2) A collective term for an IOMF CRU
and IOMF 2 CRU where a distinction between the two types of CRUs is not required.
I/O multifunction (IOMF) 2 CRU. An HP NonStop™ S-series customer-replaceable unit
(CRU) that connects an I/O enclosure to a processor enclosure through a ServerNet
cable and supplies power to the components within the IOMF 2 CRU as well as
redundantly to the disk drives, SCSI terminators, and ServerNet adapters in that
enclosure. The IOMF 2 CRU contains a power supply, a service processor (SP), a
ServerNet router 2, an Ethernet controller, three configurable ServerNet ports, and
three SCSI ServerNet addressable controllers (S-SACs) in a single unit. IOMF 2 CRUs
are supported on G06.10 and later software release version updates (RVUs).
load. (1) To transfer the HP NonStop Kernel operating system image or a program from disk
into a computer’s memory so that the operating system or program can run. (2) To
insert a tape into a tape drive, which prepares it for a tape operation (read or write).
low-level link. A connection between the TSM client software running on a system console
and the master service processors (MSPs) on a NonStop S-series server. When the
NonStop Kernel operating system is not running, communication must take place over
a low-level link. You can also communicate with a NonStop S-series server over a
low-level link when the operating system is running. See also service connection.
multifunction I/O board (MFIOB). A ServerNet adapter that contains ServerNet
addressable controllers (SACs) for SCSI and Ethernet; a service processor; ServerNet
links to the processor, to the two ServerNet adapter slots, and to one of the ServerNet
expansion board (SEB) slots; and connections to the serial maintenance bus (SMB),
which connects components within an enclosure to the service processor.
Online Support Center (OSC). The group of support specialists within the HP Global
Customer Support Center (GCSC) who respond to telephone calls regarding system
problems and diagnose malfunctioning systems using remote diagnostic links. See
also Global Customer Support Center (GCSC).
operating system image. See OSIMAGE.
OSIMAGE. A file built by the SYSGENR program and Subsystem Control Facility (SCF) that
contains the complete image of the NonStop Kernel operating system that runs in each
processor in the system.
