Listing Subsystem Status: Example 4
In this example, a Subsystem Status report is requested.
//LISTDAT4 JOB ...
//STEP1 EXEC PGM=IDCAMS
//LISTVOL2 DD UNIT=3390,VOL=SER=VOL269,DISP=SHR
//SYSPRINT DD SYSOUT=A
//SYSIN DD *
LISTDATA STATUS FILE(LISTVOL2) WTO
/*
The LISTVOL2 DD statement specifies a 3390 unit for which subsystem
status is reported. The LISTDATA command parameters are:
- STATUS, which specifies that a Subsystem Status report be printed.
- FILE, which specifies LISTVOL2 as the DD statement that allocates a 3390 unit and volume VOL269.
- WTO, which specifies that informational messages on the system
console are displayed indicating the status of the subsystem, NVS,
DASD fast write, and the duplex pair if the addressed device is one
of a duplex pair. For example, WTO can produce messages similar to
the following:
IDC01552I SUBSYSTEM CACHING STATUS: ACTIVE-DEV X'123' IDC01553I NVS STATUS: DEACTIVATED-PROCESSOR/SF-DEV X'123' IDC01554I DASD FAST WRITE STATUS: ACTIVE-DEV X'123' IDC01555I DUPLEX PAIR STATUS: PENDING-PRI DEV X'123' SEC DEV X'01' IDC01556I CACHE FAST WRITE STATUS: DISABLED-DEV X'123'
