Troubleshooting 

 

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 is not exceeding 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 resent 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. 

 

Reboot the library by turning power off from the rear of the 
library and then on. 

 

Reboot the host system when the library has completed its 
power on sequence. 

 

Contact your service representative. 

Table 13. Troubleshooting Matrix   Library Performance with Solution 

The library is not efficiently 
backing up data 

 

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 resent patches to support the tape 
drive and the library. 

 

Connect the library to an LVD SCSI bus and make sure there 
are no SE devices on the same bus, because this causes the 
entire bus to negotiate down to SE speed. 

 

Clean the tape drive. See 

Cleaning Tape Drives

. 

 

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.

Cannot load the cleaning 
Cartridge 

 

Make sure there is no cartridge present in the drive before you 
load a cleaning cartridge. 

 

Make sure the cleaning cartridge is not expired.
