Use request type PDELPATH to delete PPRC paths. This invokes ANTRQST
ILK=PPRC REQUEST=PDELPATH.
- DEVN(devn)
- Specifies the hexadecimal device number to be used for I/O. This
device number must identify a CKD device defined to the host system
that is making the request. It is required.
- PLSS(plss)
- Specifies the hexadecimal logical subsystem number (LSS) within
the primary storage subsystem. PLSS is required for storage subsystems
with logical subsystems and is invalid for 3990 and other 3990-compatible
storage controls.
- PSERIAL(pserial)
- Specifies the EBCDIC serial number of the primary storage control.
It is required. Specifying this parameter indicates that PPRC LINKs
between the subsystems use ESCON® communication
protocols. PSERIAL requires the SSERIAL parameter. PSERIAL is mutually
exclusive with PWWNN.
- PWWNN(pwwnn)
- Specifies the hexadecimal world wide node name (WWNN) of the primary
storage control. It is required. Specifying this parameter indicates
that PPRC LINKs between the subsystems use Fibre Channel Protocol
(FCP) communication protocols. PWWNN requires the SWWNN parameter.
PWWNN is mutually exclusive with PSERIAL
- PSSID(pssid)
- Specifies the hexadecimal subsystem identifier (SSID) of the primary
storage control. It is required.
- SLSS(slss)
- Specifies the hexadecimal logical subsystem number (LSS) within
the secondary storage subsystem. SLSS is required for storage subsystems
with logical subsystems and is invalid for 3990 and other 3990-compatible
storage controls.
- SSERIAL(sserial)
- Specifies the EBCDIC serial number of the secondary storage control.
It is required. Specifying this parameter indicates that PPRC LINKs
between the subsystems use ESCON communication
protocols. SSERIAL requires the PSERIAL parameter. SSERIAL is mutually
exclusive with. SWWNN.
- SWWNN(swwnn)
- Specifies the hexadecimal world wide node name (WWNN) of the secondary
storage control. It is required. Specifying this parameter indicates
PPRC LINKs between the subsystems use Fibre Channel Protocol (FCP)
communication protocols. SWWNN requires the PWWNN parameter. SWWNN
is mutually exclusive with SSERIAL.
- SSSID(sssid)
- Specifies the hexadecimal subsystem identifier (SSID) of the secondary
storage control. It is required.
- OPENDVCS(NO | YES)
- Indicates if the request is for Open System (fixed block) devices.
- NO
- The device specified with DEVN, as well as the primary and secondary
devices, are CKD devices. This is the default.
- YES
- The values supplied for the primary and secondary devices (SSID,
Serial, LSS and LUN) apply to Open Systems devices and not the CKD
DEVN device. The DEVN parameter identifies a CKD device used for receiving
the request.
- WAITTIME(waittime | 0)
- Specifies the number of seconds that SDM must wait for a request
to complete. A value of zero specifies that the request should not
be timed. Valid values are 0 through 65535.
The default is 0.
- SUBCHSET(subchset | 0)
- Specifies the subchannel set in which the command is to be issued.
The subchannel set where the I/O will be issued is the subchannel
set as defined in the Hardware Configuration Dialog (HCD). The valid
values are determined by what is supported by the host system's processor
and configured for the device.
If you omit the parameter, the command
is issued to the device that is logically in subchannel set 0. If
a swap has occurred, this could be the device that was defined in
an alternate subchannel set in the I/O configuration (IODF), with
HCD.
