RDCBK DSECT
Cross Reference (Contains links to field and bit definitions)
RDCBK Prolog
NAME : HCPRDCBK
DESCRIPTION: Real Device Characteristics Block
DSECT : RDCBK
FUNCTION : The Real Device Characteristics Block contains
DEVICE/CONTROL UNIT information. This data is
divided into two parts:
- static device information.
- 64 bytes of information returned from a
RDC (Read Device Characteristics) CCW.
LOCATED BY : RDEVRDCA Field of the RDEV.
SYSRDCA Field of the SYSCM
- Address of the first RDCBK entry
CREATED BY : RDCBK'S are dynamic and in part are created by the
device specific initialization modules.
RDCBK'S also acquire their data from a Read Device
Characteristic CCW during device initialization.
DELETED BY : RDCBK'S are created at Initialization or the
Vary Online command and are never deleted.
SERIALIZED : RDEV Lock
COMMENTS : When using this block for FBA DASD, the
first 8 bytes should not be included
since the RDC CCW doesn't return this
information. Therefore to use this
DSECT when issuing the RDC CCW, the data
returned must be placed starting at
RDCFBARE.
Notes : Field RDCFBARE is defined
starting at location RDCOPER (RDCFEAT+2).
