Isolating Drive Sled Problems - IBM TS3100 Setup, Operator, And Service Manual

6. If the power supply seems to be delivering power to the library (Operator Control Panel and front
panel LEDs might be functioning); however, air does not flow from the power supply-cooling fan grill
on the rear of the library, replace the power supply (see "Replacing a power supply" on page 231).
7. If the power supply seems to be delivering power to the library (Operator Control Panel and front
panel LEDs might be functioning), and air is flowing from the power supply-cooling fan grill on the
rear of the library, observe the "Green" LED (lowest of the three). If it is lit, the power supply is OK.
Note: If your library has -04 level redundant power supplies (see label on top of power supply), it is
normal for the one in "Standby" mode to turn its "Green" LED off. You can test this power supply by
pulling the power connector from the other "Active" power supply. The power supply that was in
"Standby" mode is now "Active", and its "Green" LED lights. If it does not, replace it (see "Replacing a
power supply" on page 231).
If your library has -05 level redundant power supplies, the "Green" LED is ON on both power
supplies. If both "Green" LEDs are not ON, replace the failed power supply (see "Replacing a power
supply" on page 231).
8. If the "Green" LED is not lit, and it is the only one in the Library, replace it (refer to "Replacing a
power supply" on page 231).

Isolating drive sled problems

About this task
Before a drive sled CRU is replaced, verify that the following activities are completed:
Procedure
1. BEFORE POWERING OFF THE LIBRARY, write the drive memory dump to flash. It is important to
preserve the drive memory dump on the drive for analysis by IBM technical support. For
instructions, see "Before you begin" on page 260.
Note: If you are instructed by IBM technical support to copy the drive memory dump to your host
computer, use one of the following methods:
v Web User Interface: See "Service Library: Save Drive Dump" on page 154.
v ITDT: See "IBM Tape Diagnostic tool (ITDT)" on page 218.
2. Ensure that the drive firmware is at the latest level (visit http://www.ibm.com/storage/). To
determine current library and drive firmware version with the Operator Control Panel:
v Library firmware: Monitor > Library > Identity
v Drive firmware: Monitor > Drives > Identity (select a drive) Drive firmware is identified in the
FW Rev field.
3. Try reseating the drive sled.
Note: The drive sled is hot-pluggable so it is not necessary to power off the library. See
"Removing/installing/adding a tape drive sled" on page 223.
4. Cycle power to the library.
5. If air does not flow from the drive sled cooling fan grill on the rear of the library, replace the drive
sled CRU. Several library error codes also point to cooling problems. See "Removing/installing/
adding a tape drive sled" on page 223.
6. If the drive is experiencing permanent or temporary errors or if the amber Clean LED is lit on the
front panel of the library, select Clean Drive from the Operator Control Panel Service menu (Service
> Service > Clean Drive) and clean the drive. Use only an approved cleaning cartridge (see
"Cleaning cartridge" on page 168).
7. Run the Library Verify Diagnostic, which includes a drive performance read/write test. Be sure to
use a known good scratch or blank data cartridge.
