Solution
Make sure that the correct host controller card is installed.
Verify that the SCSI cables are not damaged and that the total
SCSI cable length does not exceed the maximum required length.
Verify that the drive SCSI IDs are set to unique SCSI IDs that are
not used by any other SCSI device on the same bus.
Verify that the host application and the device drivers are installed
with the most recent patches to support the tape drive.
Issue a system reset from the front panel or remote management.
Make sure the tape drive is properly inserted into the bay.
Power cycle the library. If you use redundant power supplies,
remember to turn both switches OFF.
Reboot the host system when the library has completed its power
on sequence.
Contact your service representative.
Solution
Check the network bandwidth from the host system. If you are
backing up data over a network, consider comparing to a local-
only backup.
Verify that the host application and the device drivers are installed
with the most recent patches to support the tape drive and the
library.
Make sure that you don't have any bottlenecks in the path
between the tape drive and the SAS host controller. If you use
SAS extenders, make sure that the extenders have the same or
higher maximum speed than the tape drive and host controller.
Connect the library to a LVD SCSI bus and make sure there are
no SE devices on the same bus, otherwise this will cause the
entire bus to negotiate down to SE speed.
Clean the tape drive. See
Try a new cartridge. A marginal cartridge can cause performance
problems due to bad spots on the tape requiring retries.
Backing up compressed data lowers performance.
Check the size of the files. Small file size can impact
performance.
Solution
Make sure there is no cartridge present in the drive before you
load a cleaning cartridge.
Make sure the cleaning cartridge has not expired.
Contact your service representative.
