Virtual<br />

F<strong>CP</strong><br />

Privilege Class: G<br />

Use QUERY VIRTUAL F<strong>CP</strong> to display status of the Fibre Channel Protocol (F<strong>CP</strong>)<br />

adapter devices accessible to your virtual machine.<br />

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

is displayed:<br />

F<strong>CP</strong> vdev ON DEV rdev UNIT unit CHPID chp SUBCHANNEL = vsub<br />

vdev [QDIO-ELIGIBLE|QDIO PENDING ACTIVE|QDIO ACTIVE|QIOASSIST status]<br />

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

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

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 />

identifies the virtual device number of the F<strong>CP</strong> device.<br />

rdev<br />

identifies the real device number of the F<strong>CP</strong> device.<br />

CHPID chp<br />

identifies the real CHPID number of the F<strong>CP</strong> device.<br />

SUBCHANNEL = vsub<br />

identifies the virtual machine to which your CTCA is connected.<br />

QUERY VIRTUAL F<strong>CP</strong><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 the<br />

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

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

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

QDIO ACTIVE<br />

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

data queues. Direct data transfer between the specified F<strong>CP</strong> device <strong>and</strong> the<br />

program may now occur.<br />
