QUERY VIRTUAL OSA<br />

►►<br />

Query<br />

Authorization<br />

Purpose<br />

Virtual<br />

Responses<br />

OSA<br />

Privilege Class: G<br />

Use QUERY VIRTUAL OSA to display status of the Open Systems Adapter (OSA)<br />

devices accessible to your virtual machine.<br />

For each OSA device dedicated to your virtual machine configuration, the following<br />

is displayed:<br />

OSA vdev {ON DEV rdev } [SUBCHANNEL = vsub] [(OSA AGENT)]<br />

{ON NIC vdev AS UNIT unit}<br />

For each OSA device that uses the Queued Direct I/O (QDIO) hardware, the<br />

following is displayed:<br />

vdev {QDIO-ELIGIBLE }<br />

{QDIO PENDING ACTIVE}<br />

{QDIO ACTIVE }<br />

{QIOASSIST status }<br />

If the subchannel for the OSA device is in either QDIO PENDING ACTIVE or QDIO<br />

ACTIVE state, the following line is displayed for each input <strong>and</strong> output data queue<br />

that was established by a program running in a V=V virtual machine only:<br />

vdev type sync priority IOCNT = nnnnnnnn ADP = nnn PROG = nnn UNAVAIL = nnn<br />

vdev BYTES = nnnnnnnnnnnnnnnn<br />

The terms shown in the above Results have the following meanings:<br />

vdev<br />

is the virtual device number of the OSA device.<br />

rdev<br />

is the real device number of the OSA device.<br />

SUBCHANNEL = vsub<br />

identifies the virtual subchannel number.<br />

OSA AGENT<br />

indicates that the device is an OSA Agent.<br />

QUERY VIRTUAL OSA<br />

QDIO-ELIGIBLE<br />

indicates that the device is eligible to use the QDIO Hardware Facility for direct<br />

data transfer.<br />

QDIO PENDING ACTIVE<br />

indicates that a program running in the virtual machine has established QDIO<br />

data queues for transferring data between the program <strong>and</strong> the specified OSA<br />

device. Although the data queues are created, they must be activated by the<br />

program running in the virtual machine before data transfer can commence.<br />
