Use request type PRECOVER to recover data on the recovery system.
This invokes ANTRQST ILK=PPRC REQUEST=PRECOVER.
- DEVN(devn)
- Specifies the hexadecimal device number to be used for I/O. It
is required. This device number must identify a CKD device defined
to the host system that is making the request.
- PCCA(pcca)
- Specifies the hexadecimal channel connection address (CKD device
CCA) or logical unit number (fixed block device LUN) of the primary
device. 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.
- PSSID(pssid )
- Specifies the hexadecimal subsystem identifier (SSID) of the primary
storage control. It is required.
- SCCA(scca)
- Specifies the hexadecimal channel connection address (CKD device
CCA) or logical unit number (fixed block device LUN) of the secondary
device. 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.
- 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 to the
CKD DEVN device. The DEVN parameter identifies a CKD device used for
receiving the request.
- OLDVOLSER(oldvolser)
- Specifies the old volume serial number. PPRC verifies the OLDVOLSER
contains characters and compares the device volume serial number to
the OLDVOLSER value. If the volume serial numbers are equal, PPRC
resets the volume to simplex state. OLDVOLSER is required if you
specify NEWVOLSER.
- NEWVOLSER(newvolser)
- Specifies the new volume serial number. If you specify NEWVOLSER,
you must specify OLDVOLSER. PPRC verifies the OLDVOLSER contains characters
and compares the device volume serial number to the OLDVOLSER value.
If the volume serial numbers are equal, PPRC resets the volume to
simplex state and replaces the old volume serial number with the new
volume serial number.
- 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.
