the interface communication path, run the Test Device function, if available,
after the drive is selected. This function writes and reads data across the
interface, also sending a command to the drive to run the internal performance
read/write test.
6.
If the host tool, ITDT, cannot detect the drive or library, look for problems with
the host interface cabling, the HBA, the device driver, or the backup application
software.
Isolating Web User Interface problems
1.
Verify that you entered the account name and password correctly. The account
name and password are case-sensitive.
2.
Verify that other library users are not entering commands from the Web User
Interface or Operator Panel at the same time you are issuing commands.
3.
Ensure that library firmware is at the latest level (visit
4.
Ensure that the Ethernet cable is securely plugged in the rear of the library at
the Ethernet port.
5.
Ensure that the correct IP, netmask, and gateway addresses are keyed into the
network parameters.
6.
Ensure that the correct IP address is being used on the web browser.
7.
If the Ethernet connection is a direct connection between the PC and the library,
a special "crossover" Ethernet cable is required.
Note:
On newer PCs, either straight through or crossover Ethernet cables might
be used since the crossover requirement is provided internally.
8.
Check the Ethernet cable carefully (or try another cable) and, if the cable is
connected to a network hub or switch, try a different port.
9.
If the Web User Interface is still malfunctioning, refer to “Contacting Dell
technical support” on page 7-2.
Isolating host attachment interface problems
After successfully exercising “Isolating drive problems” on page 6-6, and more
specifically “Running library verify diagnostic procedures” on page 4-14 from the
Operator Panel (Service > Library Verify), the following procedures are suggested
to help isolate the failure to properly establish connectivity to the Host Bus adapter
(HBA).
1.
Use the ITDT-DCR utility to evaluate connectivity from the HBA through the
cabling to the drive. ITDT-DCR does not require separate device drivers, thus
the Operating System can scan, and find all the LTO devices that are attached.
a.
If ITDT-DCR cannot successfully locate the LTO drive, suspect cabling or
HBA problems, and skip to Step 4.
b.
If ITDT-DCR successfully located the LTO drive, proceed to Step 3. See
“ITDT-DCR” on page 7-1 for a brief description of ITDT-DCR and
instructions on how to download the tool from the web.
2.
If ITDT-DCR successfully locates the LTO devices, verify that the correct
application device drivers and backup application software is properly
installed.
3.
Ensure that all the required or latest available Operating System files or
updates (DLLs, PTFs) are installed and applied.
