QUERY WRKALLEG
Use QUERY WRKALLEG to display the status of working allegiance for each virtual
device given. The device must be a minidisk.
ALL
will display all the virtual devices in the user’s configuration that have
WRKALLEG ON.
vdev
vdev1-vdev2
is the virtual device number or a range of virtual device numbers of the
minidisk.
1. If no virtual device is specified, all the virtual devices that are simulating working
allegiance will be displayed.
2. VM supports a z/OS guest’s participation in a Sysplex configuration only if all
participating z/OS systems are guests of the same VM host. Environments
which include a z/OS system running natively in a separate processor partition,
or as a guest of a different VM system are not supported.
3. This command is rejected for full-pack minidisks on a shared real volume.
Virtual working allegiance is incompatible with sharing real DASD. WRKALLEG
is only for sharing virtual devices.
4. This command is rejected for dedicated DASD. Working allegiance is only
necessary for shared minidisks. Virtual working allegiance is incompatible with
sharing real DASD. WRKALLEG is only for sharing virtual devices.
5. Working allegiance applies only to users with write access to the minidisk.
Furthermore, working allegiance is simulated only when a guest with write
access initiates I/O. However, guests with read-only access will be allowed to
query the device to determine if another guest issued SET WRKALLEG ON to
the minidisk.
6. Working allegiance is always simulated for virtual disks in storage. QUERY
WRKALLEG is rejected if the vdev is a virtual disk in storage.
7. The WRKALLEG setting applies to the minidisk, not to an individual virtual
device. If two users have links to the same minidisk and one issues SET
WRKALLEG, the setting will apply to both users’ access to the minidisk.
