67 StorageLoader Installation and User Manual
SOLUTION
• Make sure that all SCSI devices on the same bus have unique ID numbers.
• If the SCSI bus is narrow (50-pin) only SCSI IDs 0 through 7 are available.
• Make sure that you power cycle the loader after changing the SCSI ID.
• Reboot the host server system.
• Make sure that LUN scanning is enabled on the host.
• Verify that a SCSI terminator is attached to both the last and first SCSI
device on the SCSI bus.
• Verify that the SCSI cables are connected to the rear of the loader. See
Chapter 3.1.7. Step 7. Connecting the SCSI Bus Cable (SCSI only).
• 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 ID is set to a unique SCSI ID that is 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 loader
• Power cycle the loader by turning power off from the rear of the loader and
then on.
• Reboot the host system when the loader has completed its power on
sequence.
• Contact your service representative.
• Verify that the host application and the device drivers are installed with the
most resent patches to support the tape drive
• Reboot the host system when the loader has completed its power on
sequence.
• Contact your service representative.
