After performing one of the preceding actions, reissue the DEVSERV QPAV command and

Verifying Hyper Parallel Access Volumes aliases from z/OS on z/VM
When you restart a P9500 storage system while using Hyper Parallel Access Volumes, you must
verify that the correct aliases are sustained to a CU.
To verify Hyper Parallel Access Volumes aliases on a z/OS system (which is a guest OS on z/VM):
1.
Enable the Hyper Parallel Access Volumes option on the z/VM and on the z/OS.
2.
Issue the QUERY PAV command from z/VM to verify that the displayed aliases are those
assigned for Hyper Parallel Access Volumes. See
for
proper syntax and an example of this command.
3.
Issue the DEVSERV QPAV command from z/OS to verify that the displayed aliases are those
assigned for Hyper Parallel Access Volumes. See
“DEVSERV QPAV commands” (page 20)
for proper syntax and an example of this command.
4.
If the correct aliases for Hyper Parallel Access Volumes do not appear after running the QUERY
PAV and DEVSERV QPAV commands, and if the host only accesses the corresponding P9500,
disable the Hyper Parallel Access Volumes option on the host computer, and then enable the
option again. Skip to step 5.
If the host accesses other storage systems that use Hyper Parallel Access Volumes, perform
the following procedure:
1.
Issue the following command from z/OS which is used as a guest OS on z/VM to all
base devices in the corresponding CU.
V base_device_number1-base_device_number2,OFFLINE
2.
Issue the following commands from z/VM to all base devices and alias devices used for
Hyper Parallel Access Volumes in the corresponding CU.
DET alias_device_number1-alias_device_number2
DET base_device_number1-base_device_number2
VARY OFFLINE alias_device_number1-alias_device_number2
VARY OFFLINE base_device_number1-base_device_number2
VARY OFFLINE CHPID channel_path1
VARY OFFLINE CHPID channel_path2
:
VARY ONLINE CHPID channel_path1
VARY ONLINE CHPID channel_path2
:
VARY ONLINE base_device_number1-base_device_number2
VARY ONLINE alias_device_number1-alias_device_number2
ATT base_device_number1-base_device_number2*
ATT alias_device_number1-alias_device_number2*
3.
Issue the following command from z/OS to all base devices in the corresponding CU.
V base_device_number1 - base_device_number2,ONLINE
4.
Issue the following command from z/OS to all channel paths configured on the
corresponding CU. This command must be issued for each channel path.
V PATH(base_device_number1-base_device_number2, channel_path),ONLINE
5.
Reissue the DEVSERV QPAV command and check for the alias devices in the returned results.
