Solution

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :  Customer must place drive offline.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Have customer place the drive offline.

2. Open right side door.

3. At operator panel, consult drive's status (see Table 2-9 on page 2-53). (L700/1400 Service Manual, PN95846)

Does panel display:
-"Not communicating?"
-"Not functional?"
Yes: Go to step 4.  No: Go to step 6.

4. Is drive firmly seated into connector? Yes: Go to step 5.
No: Firmly seat drive into connector.  Go to step 5.

5. Is drive AC switch in on (|) position? Yes: Go to step 6.
No: Set switch on. If drive still fails to function, go to step 10.

6. At operator panel, consult drive's status (see Table 2-9 on page 2-53). (L700/1400 Service Manual, PN95846)
Does panel display "Unknown drive?"
Yes: Check drive type to be sure it matches system requirements. This can be checked in "Lib Config Menu" and "Lib SCSI I/F Config Menu" on operator panel.
No: Go to step 7.

7. At the operator panel, consult drive's status (see Table 2-9 on page 2-53). (L700/1400 Service Manual, PN95846)

Does panel display "Not connected?"
Yes: Drive's Tape Transport Interface (TTI) connector is not firmly connected or AC switch may be off. See steps 4 and 5.
No: Go to step 9.

8. Check host-to-drive cable connection at library bulkhead (SCSI) or fiber component & at drive.
Is cable the correct type & is connection good?
The correct lengths & types of connectors are discussed in Table 1-3 on page 1-6. (L700/1400 Service Manual, PN95846)
Yes: Go to step 10.
No: If cable is:
-Incorrect type---schedule time to replace cable.
-Incorrectly connected or connector is damaged---schedule time to replace cable.

9. If possible, obtain tape that was mounted on drive at time of error.
Have operator make another drive offline and use a system diagnostic test with this tape on that drive.
Was an error encountered? Yes: Go to step 10. 
No: If the cable is incorrect type or incorrectly connected or connector is damaged - schedule time to replace cable.
Yes: Have the operator remove the tape from the system pool.
No: Go to step 10.

10. Drive replacement:

CAUTION:
System interruption: To avoid a system interruption, be sure to carefully follow the step below when replacing the drive.
a. Place the replacement drive in a convenient position near the defective drive's position.
b. Have the operator quiesce the system's SCSI/fiber bus to the drive and make the drive unavailable to the system.
c. Replace the drive:
1. For DLT drives, follow the procedure in "DLT 4000/7000E/8000 Tape Drive" on page 5-67 to replace the drive. (L700/1400 Service Manual, PN95846)
2. For Ultrium drives, follow the procedures in Chapter5 for the specific drive manufacturer.

CAUTION:
Special information for T9x40 and T10000 drives: Consult the T9x40 Tape Drive Service Reference Manual or T10000 tape Drive Service Manual for drive configuration options. The library automatically assigns the same address to the replacement drive. However, you may need to configure other information for the drive before performing the swap.

3. For T9x40 drives, follow the directions in the T9x40 Tape Drive Service Reference Manual to replace the drive.
4. For T10000 drives, follow the directions in the T10000 Tape Drive Service Manual to replace the drive.

11. Recovery information:
Drive, library, and system recovery from the hot swap procedure is explained below.
Once the drive is replaced:
-SCSI "Bus Reset" command is not asserted during the operation
-Library senses that new drive is installed
-Library communications with drive is automatically resumed
-SCSI ID of drive is automatically assigned same ID of drive that was replaced---no reconfiguration or library re-boot is required.
-Drive type, SN & FW version is automatically updated.
-Drive handle is cycled (DLT only)
-Drive is automatically available to library.
-Some system intervention may still be required to make drive available
