5 Monitoring Compatible PAV Activities
This chapter shows commands that are used to monitor Compatible PAV activities on the storage
system from the host computer.
The commands differ according to the operating system of the host computer. For z/OS, see the
following section:
•
MVS Commands (for z/OS)
•
GTF I/O tracing
For z/VM, see the following section:
•
VM CP Commands (for z/VM)
MVS Commands (for z/OS)
To monitor the Compatible PAV activities on the storage system from z/OS, use MVS commands.
In addition to the DS QPAV and D M=CHP commands the following commands will provide
additional information:
•
DISPLAY M=DEV . Figure 19 (page 35) and Figure 20 (page 35) shows an example of the
Display M=DEV(xxxx) command for a base device.
•
DEVSERV PATHS . Figure 25 (page 39) shows an example of a DEVSERV PATHS command
•
DEVSERV QPAV . Figure 26 (page 40) through Figure 32 (page 43) show output samples of
the DEVSERV QPAV commands having the following command formats:
◦ DS QP,xxxx,4 : Display status of four base devices starting at device 8300
◦ DS QP,xxxx,HPAV : Display status of Compatible Hyper PAV base devices and alias
devices
◦ DS QP,SSID=xxxx : Display status of entire Subsystem-ID
◦ DS QP,xxxx,VOLUME : Display status of host/subsystem configuration for volume
•
D IOS,HYPERPAV . “Output Sample of D IOS,HYPERPAV Command” (page 43) shows an
example of a D IOS, HYPERPAV command.
For the complete syntax of the previous commands, see IBM document GC28-1781, OS/390
MVS System Commands.
GTF I/O Tracing
GTF is PAV aware. When a device number is specified for GTF I/O tracing operations, GTF
determines if the device is a base PAV device and will automatically include the Alias addresses
currently bound to the base device.
