1. If the ITDT utility is not installed on your server, download the applicable
version for your operating system from the IBM website into a directory on
your server.
2.
When installation is complete, run the SCAN (
s
) option to determine if your
server can detect all of the Ultrium tape drive devices (including any libraries
or autoloaders that might be on the bus).
3. Select the drive that is to be tested or to have firmware downloaded.
4. For testing, select the Test Device (
t
) option.
Note: This option will perform a series of LOADS, UNLOADS, and
WRITE/READ operations. Both tape drive control commands and data
are sent to the device over the interface bus.
5.
The test will run for at least 30 minutes. If you determine that the interface
communication is operating correctly before test completes, enter the ABORT
command (
a
).
Resolving problems reported by the server
The procedure for fixing interface bus errors varies, depending on whether the
error is consistent or intermittent, and depending on your configuration. The
following section describes how to fix an error.
Fixing SAS bus errors
1. Make sure that the tape drive power is on.
2.
Make sure that the SAS cable is fully seated in the server and the tape drive.
3. Replace the SAS cable if it shows any signs of damage.
Resolving problems with the tape media
To resolve problems that are related to media, the drive firmware includes the
following capabilities:
v
Test Cartridge & Media diagnostic that verifies whether a suspect cartridge and
its magnetic tape are acceptable for use.
v
Statistical Analysis and Reporting System (SARS) to assist in isolating failures
between media and hardware. To determine the cause of failure, SARS uses the
cartridge performance history that is saved in the cartridge memory (CM) and
the drive performance history that is kept in the drive VPD (Vital Product Data)
area in NVRAM. Any failures that SARS detects are reported as TapeAlert flags
on the server (see
IBM LTO Ultrium Tape Drive SCSI Reference at
http://www-01.ibm.com/support/docview.wss?uid=ssg1S7001045&aid=1.).
Attention: If you insert the IBM LTO Ultrium Data Cartridge into another
manufacturer's drive, the SARS data in the cartridge memory might become lost
or invalid.
If you encounter a media-related problem, see “Function code E: Test cartridge &
media” on page 33.
Replacing the tape drive
The drive is a Tier 1 customer replaceable unit (CRU). Replacement of Tier 1 CRUs
is your responsibility. If IBM installs a Tier 1 CRU at your request, you will be
charged for the installation.
