Isolating accessor scanner problems If the server reported inventory problems relating to inability to read bar code labels, or, if some or all of the cartridge labels are not displayed on the Web User Interface, use the following procedure to determine if the scanner (library enclosure CRU) must be replaced. 1. Ensure that a supported bar code label (or labels) are being used. 2. With library power OFF, reseat the library controller card CRU (see "Replacing a library controller card" on page 10-10), and then switch library power ON. 3. Perform a re-inventory via the Operator Control Panel (Control > Re-Inventory) and view the inventory via the Web User Interface (Monitor Library > Inventory) to determine if the labels are now read. 4. If the labels are still not read properly, please contact Dell technical support.

Ensure that the latest available Operating System files or updates (dll's, PTFs, and others) are installed and applied. Identifying a suspect cartridge The amber Attention LED is lit on the front panel of the library when there is a failure that indicates a piece of media is bad, marginal, or invalid. It is cleared when all invalid cartridges are exported from the library. Note: The amber LED might also be lit because a power supply, or a power supply fan is failing.

5.
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.
6.
If the Web User Interface is still malfunctioning, replace the Library Controller
Card CRU (refer to “Replacing a library controller card” on page 10-10).
Isolating accessor scanner problems
If the server reported inventory problems relating to inability to read bar code
labels, or, if some or all of the cartridge labels are not displayed on the Web User
Interface, use the following procedure to determine if the scanner (library
enclosure CRU) must be replaced.
1.
Ensure that a supported bar code label (or labels) are being used.
2.
With library power OFF, reseat the library controller card CRU (see “Replacing
a library controller card” on page 10-10), and then switch library power ON.
3.
Perform a re-inventory via the Operator Control Panel (
Control
>
Re-Inventory
) and view the inventory via the Web User Interface (
Monitor
Library
>
Inventory
) to determine if the labels are now read.
4.
If the labels are still not read properly, please contact Dell technical support.
Isolating host attachment interface problems
After successfully exercising "Isolating Drive Sled Problems", and more specifically
the "Library Verify" diagnostic test on the Operator Control Panel (
Service
>
Library Verify
) which includes a drive (or drives) read/write diagnostic test, the
procedures are suggested to help isolate the failure to properly establish
connectivity to the Host Bus adapter (HBA).
1.
Use the ITDT utility to evaluate connectivity from the HBA through the cabling
to the drive (or drives). ITDT does not require separate device drivers, thus the
Operating System can scan, and find the LTO devices that are attached. If ITDT
cannot successfully locate the LTO drive, suspect cabling or HBA problems, and
skip step 2. If ITDT successfully located the LTO drive, proceed to step 2. See
“The ITDT firmware update, dump retrieval and drive test tool ” on page 9-4
for a brief description of ITDT and instructions on how to download the tool
from the web.
2.
If ITDT successfully locates the LTO devices, verify that the correct application
device drivers and backup application software are properly installed.
3.
Ensure that the latest available Operating System files or updates (dll’s, PTFs,
and others) are installed and applied.
Identifying a suspect cartridge
The amber
Attention
LED is lit on the front panel of the library when there is a
failure that indicates a piece of media is bad, marginal, or invalid. It is cleared
when all invalid cartridges are exported from the library.
Note:
The amber LED might also be lit because a power supply, or a power
supply fan is failing. See “Isolating a power supply problem” on page 7-8.
1.
Identify the media with the Web User Interface (
Monitor Library
>
Inventory
).
Expand the cartridge details for each magazine and look for media status in the
Attn
column of the inventory table.
2.
Make note of the cartridge location (Slot #) and VOLSER (Label) in the
inventory table.
3.
To remove the cartridge from the library:
