• After rewind, the drive should be ready and Idle with cartridge not ejected.
• Eject the cartridge. After ejecting, the drive should be ready, idle, and empty.
Note: A drive reset may be used as an alternative to a power cycle, but if the drive is hung or the reset
does not recover the drive, then a power cycle must be done anyway. To reset the drive, use the library
or application interface. If the drive eject button is visible, the drive may be reset by holding down the
reset button for 10 seconds.
4. If the drive is not showing an error code, but will not become ready and Idle, then remove it from the
system, review the install procedures, and install it again.
5. Check all cables for damage or bad connections and make sure all connection LEDs are lit.
If the drive does not become ready, idle and empty, then replace the drive. Otherwise continue with the
next section.
B. Determine if the problem is the drive hardware or something else
1. Clean the drive by loading a cleaner cartridge.
• Check to see if the application or library indicates the drive needs cleaning.
• If the drive SCD is visible and shows a solid “C” code, the drive needs to be cleaned.
• Cleaning the drive is always a good action before you decide to replace it.
2. Retry the operation with another cartridge or try the cartridge on another drive.
• Track failing cartridges and replace them, if they are bad, instead of the drive.
3. If there is a persistent error condition, check product documentation for the meaning of any code and
correct the situation.
• Take a drive dump and save product logs immediately after the error and determine the specic error
code or save the information for service support to determine the issue.
• The issue could be cooling, power, rmware, media, an encryption issue, a write protected cartridge,
etc. Take corrective action for the specic error code before replacing the drive.
4. If you suspect that drive is bad, run a drive test.
• The preferred drive test is the IBM Tape Diagnostic Test Tool (ITDT) “Standard test”.
• Be sure and use a known good cartridge for the drive test.
• Alternatively, libraries and applications usually contain drive test functions.
• If the drive front panel is available, the built-in tape drive diagnostics self-test #1 can be run.
If the drive fails the test with a known good, cartridge replace the drive. Otherwise, continue with the
next step.
5. If the tape operations fail, but the tape drive is good, the issue may be something else in the system.
• Check setup and troubleshooting documentation for other components in the system: disk drives,
adapter cards, switches, etc.
• Check software set up, conguration and troubleshooting documentation.
• Load the latest recommended rmware and device drivers for the tape drive and other components
in the system.
If you are not able to x the problem, call service support and have the drive logs available.
Understanding fault indicators
When the library has a fault, there are messages and indicators that alert the user to the problem.
The library base module has error and warning LEDs on the front panel (see Figure 56 and table 33). Many
of the library components have status LEDs which are visible on the rear of the library. The Management
GUI provides fault indicators.
