LISTDATAThe LISTDATA command can be used to obtain the following reports:vvvvvSubsystem Counters report, which is a record of the counters within thesubsystem at the time the report is requested.Subsystem Status report, which is a record of the status within the subsystem atthe time the report is requested.Pinned Track to Data Set Cross Reference report, which is a report of pinnedtracks in cache and NVS cross-referenced to the data sets involved.Device Status report, which is a report of device status with both the channelconnection address (CCA) and the director-to-device connection (DDC) address<strong>for</strong> each device. This report is useful in determining the state of devices that areused in a dual copy pair (usually called duplex pairs).RAID Rank Counters report, which contains data on logical, not physical,volumes on the RAID disk. This report is issued when COUNTS SUBSYSTEM orCOUNTS ALL are specified.The syntax of the LISTDATA command is:||||||||||LISTDATA[{COUNTS|STATUS|PINNED|DSTATUS|ACCESSCODE}][{FILE(ddname)|{VOLUME(volser)+ ][UNIT(unittype)}|][UNITNUMBER(devid)}][DEVICE|SUBSYSTEM|ALL][ LEGEND|NOLEGEND]][OUTFILE(ddname)|OUTDATASET(dsname)][WTO]||||||||||||||||LISTDATA ParametersLISTDATA can be abbreviated: LISTCThe LISTDATA command uses the following parameters.A user interface is provided specifically <strong>for</strong> callers (like an RMF* interval exit) thatdo not use access method services. This interface also allows you to obtainsubsystem status or count in<strong>for</strong>mation.Required ParametersFILE(ddname)|{VOLUME(volser)+UNIT(unittype)|UNITNUMBER(devid)}FILE(ddname)specifies the name of a DD statement that identifies the device type andvolume of a unit within the subsystem. For ddname, substitute the name of theDD statement identifying the device type and volume serial number.VOLUME(volser)specifies the volume serial number of a volume within the subsystem. Forvolser, substitute the volume serial number of the volume. Abbreviation: VOL© Copyright IBM Corp. 1973, 2004 287
