Fixing a Solid Error with One Drive on a SAS Connection
1. Verify that the power is ON to the drive.
a. Verify that the library is powered ON.
b. Verify that the power supplies (in the module containing the failing drive)
are ON.
c. Verify that the drive is fully seated in the library chassis.
2. Determine if the drive is experiencing a hang condition.
a. If a cartridge is in the drive, press the unload button.
v If the cartridge ejects, the drive does not have a hang condition, go to
step 5.
v If the cartridge does not eject, go to step 3.
b. If there is no cartridge in the drive, manually load a scratch cartridge into
the failing drive. If the cartridge loads, the drive does not have a hang
condition. Press the unload button to unload the scratch cartridge and go
to step 6.
3. Press and hold the unload button for 20 seconds. The drive will save a dump
and go into a reboot, which allows communication to the drive. Do not cycle
power (power OFF then power ON) or you will lose the dump contents.
4. Copy the Drive Dump with one of the following procedures
v If the drive is no longer hung (cartridge can be unloaded), refer to
“Diagnostic and Maintenance Functions” on page D-26 and collect the
dump on a scratch (blank) cartridge.
v If the drive is still hung, refer to “Using the ITDT SCSI Firmware Update,
Dump Retrieval and Drive Test Tool” on page 7-27 to secure the dump
using ITDT. Contact your next level of support to determine if they can use
this dump.
5. If the problem continues to be in the drive, replace the failing drive sled. Refer
to “Drive Sled” on page 8-43. When complete, go to “End of Call” on page
7-44.
6. Ensure that the SAS cables or interposers are plugged in and tightened at both
ends.
7. Ensure that the drive element address is the same as the element address
being used by the host system. From the Operator Panel, select Reports →
Library Configuration.
8. If another SAS drive is available, do the following:
a. Quiece the library from all activity and swap the drives.
b. If the problem stays with the suspect drive, replace the drive sled.
c. If the problem moves to the new drive, replace the SAS cable or interposer.
d. If the problem still exists after performing the above procedures, suspect a
host system hardware or software problem. Refer to the service
documentation for the host system.
e. Go to “End of Call” on page 7-44.
9. If another SAS drive is not available to swap, replace the SAS cable or
interposer.
10. If the problem still exists, replace the drive sled. If this does not fix the
problem, suspect that the problem is caused by host system hardware or
software. Refer to the service documentation for the host system.
11. Go to “End of Call” on page 7-44.
