Attributes, Function
Translates a real CSW into
processes the CP assist
(E610) • a virtual CSi. Also
instruction, UBTRI Relocates sense byte information. For a 3330, 3340, 3350, or 2305, computes virtual cylinder
member in bytes 5 and 6 of the sense byte data by unrelocating the real cylinder number given by the hardware. For a 2311 simulated on a 2314 or
2319, computes the appropriate status for byte 3
of the sense data fro. the real sense data qiven
by the hardware. - Pageable. Processes user termination.
Processes the DISCONN (disconnect) command.
Logs off a user. Processes the FORCE command.
Returns subpools from the free storage chain and
removes spool file blocks and allocation blocks from the dynamic paging area.
Processes the LOGOFF command.
Resident.
Storage management for EC mode virtual machine. Allocates, initializes and maintains shadow,
segment, and page tables for virtual machines
that can relocate.
Returns active shadow tables to free storage. Services page or segment exceptions for virtual
EC machines. Virtual - virtual to virtual address translation.
Allocates and initializes shadow tables.
Handles pseudo page fault interruption from a VS1 virtual machine.
Processes paging exceptions for a virtual machine
that performs Virtual (shadow) virtual-to-real address
transla tion.
Processes segment exception for a virtual machine that performs paging.
Processes the CP assist instruction, ZAPPAGE (E60B) • Processes the CP assist instruction, ZAPSEGS (E60A) • Pageable.
Simulates I/O for a virtual cbannel-to-channel
adapter.
Selectively resets a device for a virtual
channel-to-channel adapter without decoupling the
CTCA from the I-side adapter.
Does a final reset for a virtual
channel-to-channel adapter and and disconnects
the adapter from its coupled twin on the I-side
virtual machine. CP Directories 1-253

channel-to-channel adapter. Simulates the channel and device operations of
the channel-to-channel adapter (CTCA) connected
between two virtual machines under VM/370. Simulates the TEST I/O instruction for a virtual
channel-to-channel adapter that has no
interruptions pending.
Pageable.
Pr.ocesses the ATTACH and DETACH real devices and
channels) command.
Resident. Simulates all SIOs to a virtual console.
Pageable.
Handles the ATTACH command. Attaches a real
device to a user as a virtual device, or
dedicates all devices on a particular channel to
a specified user.
Pageable.
Chains RDEVBLOKs off the allocation chain
anchors.
Acquires virtual blocks for devices that are
likely to be attached by the ATTACH command. Scans the ATTACH and DETACH command lines and
checks syntax.
Pageable.
Handles the DETACH command.
Pageable. Verifies the existence of a device specified on
an ATTACH command.
Pageable.
Releases a virtual or real device from a virtual
user.
Pageable.
Attaches a virtual device to a user.
Defines a new virtual device for user.
Links a virtual DASD device to a user.
Pageable.
Processes error records from virtual machine via SVC 16.
Processes SVC 76 from DOS or DOS/VS. Processes SVC 76 from OS, VS/l, VS/2, or V"/370. 1-254 IBM VM/370 System Logic and Problem Deter.ination--Volume 1
