Troubleshooting Common Problems
This section includes information on troubleshooting common library
problems. For problems that may be related to the host or application
software, refer to the host system documentation, the application software
instructions, and Host Software and Media Errors on page 128. If these
procedures fail, contact your service representative for further assistance.
Caution Consult the system administrator before cycling power. Never
cycle power when active devices are connected to the SCSI bus
or Fibre Channel bus. Cycling power when the SCSI bus or
Fibre Channel bus is active can cause data loss or hang the host
system.
