Explanation
Initialization for an ATLDS device failed. The
device will not be brought online until the cause of the failure is
corrected. In the message text:
- dev
- The number of the failing ATLDS device
- text
- One of the following:
- LIBRARY INTERFACE IS OFFLINE
- The hardware communication path between the tape control unit
and the library manager has not been established.
Recovery Action:
Contact your hardware service representative to restore the communication
path to the library manager.
- RETURNED A ZERO LIBRARY-ID
- The hardware communication path between the tape control unit
and the library manager has been established, but the library manager
returned an incorrect library-id (zeros) to the host.
Recovery
Action: Contact your hardware service representative to repair
the library manager.
- INITIALIZATION FAILURE
- The device was defined with HCD as a LIBRARY device, but the host
was unable to obtain library information from the device. The channel
program command that failed was Read Device Characteristics (RDC).
Recovery
Action: Contact your hardware service representative to determine
the cause of the RDC failure.
- UNAVAILABLE TO LIBRARY MANAGER
- The hardware communication path between the tape control unit
and the library manager has been established, but the library manager
has 'marked' the device unavailable.
Recovery Action: Contact
your hardware service representative to repair the device and restore
its availability to the library manager.
- HCD(xxxxx-xx),DEVICE(xxxxx-xx)
- During device initialization, it was found that the LIBRARY-ID
and LIBPORT-ID specified to HCD do not match the LIBRARY-ID and
LIBPORT-ID that were assigned to the hardware during installation.
Recovery Action: Correct either the hardware or HCD. If
the hardware was in error (or was incorrectly attached to the system),
correct the hardware and then VARY the device ONLINE. Use the command
DS QT,dddd,RDC to determine the library-ID and libport-ID assigned
to the hardware. In the following example, device 2C80 is assigned
library-ID BA067 and libport-ID 01:
DS QT,2C80,RDC
READ DEVICE CHARACTERISTICS
34905434905400E0 1FD8808004000000 00000000 00000000
0BA0670100000000 4281000000000000 00000000 00000000
- ACTIVATE IODF=XX, IS REQUIRED
- The device was unavailable when the currently active eligible
device tables (EDTs) were built; the EDTs are used for device allocation.
Although the device is now available to this system, it cannot be
allocated until the EDTs are rebuilt. EDTs are rebuilt during IODF
activation.
Recovery Action: Activate the current IODF,
then VARY the device ONLINE.
- TAPE LIBRARY DEVICE aaaa (bbbbb-cc) IS A DUPLICATE OF DEVICE xxxx
(yyyyy-xx) AND IS BEING MARKED FOR DELETION
- A device with CUU=xxxx, LIBRARY-ID=yyyyy, and LIBPORT-ID=zz is
being processed and another device with CUU=aaaa, LIBRARY-ID= bbbbb,
and LIBPORT-ID=cc has been found that:
- has the same hardware reported sequence number, or
- has the same CUU, that is, xxxx=aaaa.
It is determined to be the same device and the device with
CUU=aaaa is not allowed online.
This can occur in a variety
of situations, for example, when two control units are physically
uncabled from the library, and when recabled, the port cables are
switched.
Recovery Action: Correct either the hardware
or HCD. If the hardware was in error (or was incorrectly attached
to the system), correct the hardware and then vary the device online.
Use the command DS QT,dddd,RDC to determine the library-ID and libport-ID
assigned to the hardware.
- TAPE LIBRARY DEVICE aaaa (bbbbb-cc) IS A DIFFERENT DEVICE TYPE
THAN DEVICES PREVIOUSLY DEFINED IN THE SAME STRING. THE DEVICE IS
NOT ALLOWED ONLINE
- A device with CUU=aaaa, LIBRARY-ID=bbbbb, and LIBPORT-ID=cc is
a different device type than those that were previously defined for
the same string.
Recovery Action: Correct either the hardware
or HCD. If the hardware was in error (or was incorrectly attached
to the system), correct the hardware and then vary the device online.
Use the DS QT,dddd,RDC command to determine the library-ID
and libport-ID assigned to the hardware.
- TAPE LIBRARY DEVICE aaaa (bbbbb-cc) DEFINED AS MTL BUT DEVICE
xxxx (yyyy-zz) IS REAL ATL/VTS DEVICE. DEVICE NOT ALLOWED ONLINE.
- The tape drive at address aaaa, with HCD defined
LIBRARY-ID bbbbb and LIBPORT-ID cc is
defined as an MTL resident drive (for example, MTL=YES was specified
with LIBRARY-ID and LIBPORT-ID), but the RDC data indicates that the
drive resides in the ATLDS. The device is treated as a valid ATL resident
drive.
Recovery Action: Review the HCD definition for the
device.
- TAPE LIBRARY DEVICE aaaa (bbbbb-cc) EMULATING 3490 NOT ALLOWED
ONLINE IN AN MTL.
- The tape drive at address aaaa, with HCD defined
LIBRARY-ID bbbbb and LIBPORT-ID=cc,
is defined as an MTL resident drive but is emulating a 3490 device
which is not supported in an MTL. The device is not allowed online.
Recovery
Action: Review the HCD definition for the device.
- MTL DEVICE aaaa (bbbbb-cc) IS ATTACHED TO A CONTROL UNIT THAT
IS DIFFERENT THAN THAT FOR OTHER DEVICES ALREADY IN THE POOL.
- The tape drive at address aaaa, with HCD defined
LIBRARY-ID bbbbb and LIBPORT-ID cc,
is attached to a control unit different than that for devices already
in the pool. The device is not allowed online.
Recovery Action:
Review the HCD definition for the device, and other devices with the
same LIBRARY-ID and LIBPORT-ID values. Ensure that all devices for
the same LIBRARY-ID and LIBPORT-ID values are connected to the same
control unit.
If you are replacing old or broken
hardware with new hardware, all of the devices in the device pools
affected by the hardware change must be OFFLINE. If any of the devices
fail to go OFFLINE or are in PENDING OFFLINE, and the drives are not
in use by the system, cause the devices to become OFFLINE and BOXED
by issuing the VARY OFFLINE,FORCE command. After
all of the devices are offline, you can replace the hardware.
- TAPE LIBRARY DEVICE aaaa (bbbbb-cc) NOT ALLOWED ONLINE, UNABLE
TO ADD LIBRARY TO CONTROL BLOCK.
- The tape drive at address aaaa,
with HCD defined LIBRARY-ID bbbbb and LIBPORT-ID cc,
cannot be added to the existing device pool because it is full (that
is, it already has 16 devices defined) or because the number of device
pool subsystems has reached the library limit of 128. The device
is not allowed online. The MTL device pool subsystem limit remains
at 32.
Recovery Action: Review the HCD definition for the
device, and other devices with the same LIBRARY-ID and LIBPORT-ID
values. Ensure that MTL devices are not overgenned.
- PROBLEM OBTAINING DISTRIBUTED LIBRARY DATA. LIBRARY MAY BE IN
SERVICE MODE.
- During initialization of a device in a Peer-to-Peer VTS or the
TS7700 Virtualization Engine, the
I/O operation requesting configuration data for the distributed library
either failed or returned invalid information. Also, for a device
associated with the TS7700 Virtualization Engine, it could
also mean that the library is in service mode. This message is issued
when an RDC command returned data indicating that the device is in
a Peer-to-Peer VTS library or in a TS7700 Virtualization Engine.
However, the subsequent request to obtain configuration data failed
or returned invalid data.
Recovery Action: Contact your hardware
service representative to determine the cause of the failure.
System action
The device is not available for use by the system.
System programmer response
When the condition has been corrected,
attempt to VARY the device ONLINE. If the device was previously defined
to HCD as a library device, with the proper library-ID and libport-ID,
the device will come ONLINE.
If the device is not defined with
HCD as a library device, the device will not be allowed ONLINE if
an IODF activate is required. Message ACTIVATE IODF=XX, IS REQUIRED
indicates that because of previous failure, the library-ID and libport-ID
were not known when the systems EDTs were build. Now that these IDs
are known, an activate is required in order to cause the EDTs to be
rebuilt.
