The 3592 supports forcing a diagnostic dump and storing that dump to a mounted tape cartridge or to a
host system file through 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.
Note:
• Trace data is volatile and is lost if you press Reset or power OFF the device.
• If you force a dump when the dump icon
is already displayed. The existing trace data is overlaid by
the new trace data.
You might require information from the customer during this process.
To force and store a diagnostic dump on these devices, complete 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 that is associated with the target device:
/opt/IBMtape/tapeutil -f /dev/rmt/nst -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 file name of the dump
destination file, and substituting n with the actual value from the device special file that is associated
with the dump device:
/opt/IBMtape/tapeutil -f /dev/rmt/nst -o sdp -z file -v
Note: The diagnostic dump procedure can also be completed with the menu-driven interface of the
tapeutil program. To start 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 with TAPEUTIL
Refer to the IBM SCSI Tape Drive, Medium Changer, and Library Device Drivers: Installation and User's
Guide for details of the ITDT/tapeutil program with HP-UX systems.
