Drives without Load Handles

Sun Confidential - Internal Only
■ Drives without Load Handles
See “Drive and Cartridge Compatibility” on page 1-55 for interface and cartridge/drive
compatibiliy issues.
Drives that do not contain load handles are:
• Benchmark DLT1
•SDLT
•IBM LTO Ultrium
• Hewlett-Packard LTO Ultrium
• Quantum (Certance) LTO Ultrium
The directions below describe how to remove and replace these drives. You must, h o w e ve r,
pay attention to the specific instructions that pertain to each drive type.
Drives are hot-swappable. This means they can be replaced without removing power from the library, and
the drives on the other SCSI buses can continue their data processing. This is possible because each drive
has a SCSI connector attached to the back of the drive. Only the drive that is being replaced must be
powered-off, and that drive’s SCSI bus must be quiesced.
You must follow the precautions listed below.
CAUTION:
Possible drive damage: Read the instructions in “Personal Safety”
before beginning.
Observe these precautions before beginning:
• Back up the server before removing the drive.
• If the drives are daisy-chained, stop all data processing on the channel to which the
drives are connected before disconnecting the drives.
• Make sure there is no activity on the SCSI bus before disconnecting the external
SCSI cables. Stop all processes on the host.
• Make sure all signals are terminated at each end of the SCSI bus. Do not mix single-
ended and differential terminators.
If your external SCSI cables are long enough that they do not interfere with replacing the
drive, you do not need to disconnect those cables.
CAUTION:
Possible data loss or system problem: If you must disconnect the
external SCSI cables, make sure that you quiesce the system first (stop
all processes on the drives on the SCSI bus with the drive you are
replacing).
