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)

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.
