- ,DEVN=devn
- ,VOLSER=volser
- ,UCBPTR=ucbptr
- One of the following three input parameters is required:
- ,DEVN=devn
- A parameter field containing the binary device number of a device
whose functional tracks are to be released.
To
code: Specify the RS-type address, or address in register (2)-(12),
of a 2-byte field.
- ,VOLSER=volser
- A parameter field containing the volser of a device whose functional
tracks are to be released.
To code: Specify
the RS-type address, or address in register (2)-(12), of a 6-character
field.
- ,UCBPTR=ucbptr
- A parameter field containing the UCB address of for a device
whose functional tracks are to be released.
To
code: Specify the RS-type address, or address in register (2)-(12),
of a fullword field.
- ,EXTINFO=extinfo
- A required input parameter field that is an array of eight byte
extent pairs to release. The first 4-bytes of a pair gives the starting
track address and the last 4-bytes gives the ending track address
(for a single track the two addresses would be the same).
To code: Specify the RS-type address, or address
in register (2)-(12), of a character field.
- ,EXTNBR=extnbr
- A required input parameter field that tells how many extent
pairs have been supplied in EXTINFO.
To code: Specify
the RS-type address, or address in register (2)-(12), of a halfword
field.
- ,RETINFO=retinfo
- A required output parameter field that is used to return detailed
information about the results of executing the
request. Information about the results of scheduling the
request are returned in the RETCODE and RSNCODE fields. Align the
area on a word boundary. The first 4-bytes contain the return code
and the second 4-bytes contain the reason code. The remainder of
the information is dependent on the return and reason codes. See the
coding example SDM API usability guide about how to coordinate the RETCODE,
RSNCODE, and RETINFO fields.
To code: Specify
the RS-type address, or address in register (2)-(12), of a 100-character
field.
- ,ECB=ecb
- ,ECB=NO_ECB
- An optional input parameter field that SDM will post for an
asynchronous request. This field is ignored for synchronous requests.
The default is NO_ECB.
To code: Specify the
RS-type address, or address in register (2)-(12), of a fullword field.
- ,WAITTIME=waittime
- ,WAITTIME=0
- An optional input parameter field containing how long in seconds
SDM will wait for a request to complete. A value of zero says to
not time the request. If the time expires before the request is complete
a value of RQST_WAITTIME_EXPIRED (see ANTRQSTL) will be returned.
If the request is a synchronous request the value will be placed in
the RTNCODE field. If the request is an asynchronous request the value
will be used as the ECB post code. The default is 0.
To
code: Specify the RS-type address, or address in register (2)-(12),
of a halfword field.
