- ODEVN
- Specifies address information for the open device to be queried.
(If CKD device address information is specified with this parameter,
CKD data will be returned.) The values are:
- serno
- Specifies the storage subsystem serial number, which can include
up to 12 digits depending on the type of logical subsystem.
- lun
- Specifies the 2-digit logical unit number. lun must be
specified in X'' notation.
- lss
- Specifies a 2-digit hexadecimal value that identifies the logical
subsystem for the device.
- VOLUME
- Directs PPRC to display the status of the volume that is specified
with the DEVN parameter. The default value is VOLUME.
- BITMAP
- Specifies that PPRC report the percentage of tracks that it has
copied for a pending or suspended PPRC primary volume. This option
is valid when you query a PPRC primary volume and you either specify
the VOLUME keyword, or you do not specify any optional parameters.
BITMAP is ignored if you specify the PATHS keyword. If you specify
the VOLUME keyword, the default value is BITMAP.
- NOBITMAP
- Specifies that PPRC not report the percentage of tracks that it
has copied for a pending or suspended PPRC primary volume. This option
is valid when you query a PPRC primary volume and you either specify
the VOLUME keyword, or you do not specify any optional parameters.
You
can use the NOBITMAP option to collect some data from a storage control
even when the device is unable to respond to the CQUERY command.
Example: PPRC
may not be able to collect bitmap information because the device is
disabled.
- PATHS
- Directs PPRC to display all of the paths that are associated with
the primary site storage control, and the status of each path. If
you direct this command to the secondary device, PPRC cannot make
path or storage control information available. To obtain this information,
issue the command to a volume on that storage control that is either
in simplex state or is a primary of a duplex pair.
- FORMAT
- Specifies that PPRC present the CQUERY command output in a block
format. For examples refer to Examples of CQUERY output.
The default value is FORMAT.
PPRC issues message ANTP0090I as
part of a block report when you specify the CQUERY VOLUME with FORMAT
option. PPRC issues message ANTP0095I as part of a block report when
you specify the CQUERY PATH with FORMAT option.
- UNFORMAT
- Specifies that PPRC present the CQUERY command output as in the
examples in CQUERY unformatted output for a primary volume for a volume query
and CQUERY unformatted output with the PATHS option for a paths query.
PPRC
issues message ANTP0091I as part of a block report when you specify
the CQUERY VOLUME with UNFORMAT option.
PPRC issues message
ANTP0096I as part of a block report when you specify the CQUERY PATHS
with UNFORMAT option.
- LINKINFO
- Requests that PPRC display all of the potential connectivity of
the Fibre Channel ports in the storage facility image (SFI) specified
by the DEVN parameter to each system adapter port in the SFI specified
by the SWWNN or SDEVN parameter.
- SDEVN
- Specifies the device number of the secondary volume that PPRC
is to query. The device number is the 4-digit hexadecimal address
of the device to which the I/O operation is directed.
- SWWNN
- Specifies the world wide node name of the secondary volume that
PPRC is to query. The world wide node name is the 8-byte hexadecimal
identifier of the SFI to which the I/O operation is directed.
- SUBCHSET
- 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.
- SSUBCHSET
- Specifies the subchannel set for the secondary device specified
with the SDEVN parameter. The subchannel set is the subchannel set
as defined in the Hardware Configuration Dialog (HCD). The 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.
