TS3400 Tape Library Maintenance Information
Note:
• Trace data is volatile and is lost if you press the Reset pushbutton or power OFF the
device.
• If you force a dump when the dump icon is already displayed, the existing trace
data will be overlaid by the new trace data.
You may require information from the customer during this process.
To force and store a diagnostic dump on these devices, perform the following steps:
1. Verify that the IBM tape subsystem is powered ON and online.
2. Verify that the drive is not in use by another host.
3. Verify that the drive has no customer cartridges loaded. CE Scratch Tape is OK.
4. Enter the following command to force the dump, substituting n with the actual
value from the device special file associated with the target device:
/opt/IBMtape/tapeutil -f /dev/rmt/ n st -o fdp -v
5. Determine the location for the dump to be stored (that is, floppy diskette such as
/vol/dev/aliases/ floppy0 or host file such as /tmp/diag_dump.file).
6. Enter the following command, substituting file with the actual path and
filename of the dump destination file, and substituting n with the actual value
from the device special file associated with the dump device:
/opt/IBMtape/tapeutil -f /dev/rmt/ n st -o sdp -z file -v
Note: The diagnostic dump procedure may also be performed by using the
menu-driven interface of the tapeutil program. To invoke the tapeutil program
in this format, enter the following command, then choose option
1 to open the
device, followed by option 5 to force a dump, and option 6 to store the dump:
/opt/IBMtape/tapeutil
Offloading Dumps to HP-UX System using TAPEUTIL
Refer to IBM SCSI Tape Drive, Medium Changer, and Library Device Drivers: Installation
and User’s Guide for details of the tapeutil program in the HP-UX system.
The tape drive supports forcing a diagnostic dump and storing that dump to a
mounted tape cartridge or to a host system file via the SCSI bus.
The dump icon appears when the dump is available, and remains on the screen to
indicate that trace data is stored in the device.
Notes:
• Trace data is volatile and is lost if you press the Reset pushbutton or power OFF the
device.
• If you force a dump when the dump icon is already displayed, the existing trace
data will be overlaid by the new trace data.
You may require information from the customer during this process.
