Explanation
One of the following occurred:
- The operator entered the VARY dev,OFFLINE,FORCE command.
If
the device with device number
dev was online, it
is now marked pending offline. It will go offline when two conditions
are met, in this order:
- The device is no longer allocated to any job.
- Allocation can get the necessary resources to process the request.
If device dev was offline, it remains
offline.
The operator forced the device offline and boxed the device.
The operator then tried to vary the device back online. The VARY command
is rejected for that device.
In either case, the device has been boxed, which means:
- I/O for the device has been ended.
- Any new I/O request for the device will result in a permanent
I/O error.
- No new allocations are done for the device.
In the message text:
- dev
- A VARY dev,OFFLINE,FORCE was entered to force offline the device
with device number dev.
- nnnnnnnn
- A VARY nnnnnnnn,OFFLINE,FORCE command was entered to force offline
a console named nnnnnnnn.
- PENDING
- Device number dev or a console named nnnnnnnn was
online. The system marked the device or console pending offline. The
device or console will go offline when two conditions are met, in
this order:
- The device is no longer allocated to any job.
- Allocation can get the necessary resources to process the request.
System action
Operator response
Do one of the following:
- For case number 1: No action is required. However, if the device
is pending offline and not allocated, use the D GRS,C=(SYSIEFSD,VARYDEV*)
command to ensure no contention exists for SYSIEFSD.VARYDEV* resources.
If all of the above conditions are met and no contention exists, notify
the system programmer.
- For case number 2: To bring the device back online, enter a VARY
dev,ONLINE,UNCOND command.
System programmer response
Use the D GRS,RES=(SYSIEFSD,VARYDEV*)
command to determine if the SYSIEFSD.VARYDEV resource is being used
elsewhere. If it is, monitor the resource to ensure processes using
it are releasing it as expected. If the resource is held by a process
that is hanging, attempt to cancel the job. If cancel is not possible,
contact IBM®.
