[AUTOSWITCH STATUS UNAVAILABLE

[DISPLAY TRUNCATED - INSUFFICIENT

This message appears in response to a DISPLAY U,,AUTOSWITCH
command and displays the status of all automatically switchable devices
or describes why it was unable to provide the status. See Displaying
Information About Automatically Switchable DevicesDisplaying Information
About Automatically Switchable Devices in z/OS MVS System Commands for
more information.
In the message text:
- UNIT
- The device number of an automatically switchable device.
- TYPE
- The type of magnetic tape unit, as defined through HCD (for example,
3480). Devices appear as specified through HCD. The following device
types appear in the TYPE field:
- type
- Device type, such as ‘3480’
- xxxS
- where xxx represents the first three digits
of device type (for example, ‘348’ for a 3480 or ‘349’
for a 3490) and ‘S’ means the device has a cartridge stack
loader.
- xxxL
- where xxx represents the first three digits
of a device type (for example, ‘348’ for a 3480 or ‘349’
for a 3490) and ‘L’ means the device is a library device.
- UND
- where the device is not known.
Note: If a device is both a library device and has
a cartridge stack loader, the L designation takes precedence over
the S designation.
- STATUS
- The status of the device:
- A
- Allocated
- CA
- Cartridge stack loader is active
- OFFLINE
- Offline
- RAL
- Restricted to allocation
- SYS
- Allocated to system
- SYSTEM
- The system to which the device is assigned. The system name is
one of the following:
- The name of the system, as specified on the SYSNAME parameter
of the IEASYSxx parmlib member.
- *UNKNOWN when the device is allocated but the DISPLAY command
processor cannot identify the system. In this case, the automatically
switchable device is assigned to a system that is not connected to
the same IEFAUTOS structure, or is connected to the same structure
but is using the device as a dedicated device.
- JOBNAME
- The job to which the device is allocated. The job name is one
of the following:
- The name of the job
- The name of the address space
- The name of the task created by the START or MOUNT command
- *MASTER* when the device is allocated to the master address
space
- *SYSTEM when the device is allocated to the system control
program
- *UNKNOWN when the device is allocated but the DISPLAY command
processor cannot identify the job.
- ASID
- The address space identifier (ASID) of the address space to which
the device is allocated.
- VOLSER
- The volume serial number of the device
- VOLSTATE
- How the device is to be used, either for private (PRIV) or public
(PUB) use and whether it is reserved (RESRV) or removable (REMOV).
- tsysname
- The name of the requested system.
- sysname
- The name of a system that has this autoswitchable device defined.
- sunt
- If different from the requested system, the device number as defined
on system, sysname.
- styp
- If different from the requested system, the type of magnetic tape
unit as defined on system, sysname.
If a range of devices was specified on the DISPLAY
AUTOSWITCH command and some of those devices are not automatically
switchable, they are not displayed. The additional information
in the form of sysname (sunt,styp) shows devices defined to other
systems than this one, and provides similar information to OEM tape
sharing software.
If none of the devices specified on the
DISPLAY AUTOSWITCH command are automatically switchable, message IEE455I
appears to indicate this condition.
- idr
- An identifier used with the CONTROL C,D command to cancel status
displays:
- Written on printer consoles
- Displayed inline (that is, not in a display area) on a display
console
This identifier does not appear when the display appears
in a display area on a display console.
In the message text:
- text1
is one of the following:
- [SYSTEM ERROR]
- A system error occurred.
- [DISPLAY TRUNCATED - INSUFFICIENT STORAGE]
- The system was unable to obtain sufficient storage for a display
line to complete the command.
System action
The system continues processing.
