Dell TL2000 Isolating Accessor Scanner Problems, Isolating Host Attachment Interface Problems

4.If the ethernet connection is a direct connection between the PC and the library, a special ″crossover″ ethernet cable needs to be used.

Note: On newer PCs, either straight through or crossover ethernet cables may be used since the crossover requirement is provided internally.

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 10-8).

Isolating Accessor Scanner Problems

If the server has reported inventory problems relating to inability to read bar code labels, or, if some or all of the cartridge labels are not being displayed on the Web User Interface, use the following procedure to determine if the scanner (library enclosure CRU) needs to be replaced.

1.Ensure that a supported bar code label (or labels) are being used. .

2.With library power OFF, reseat the control card CRU (refer to “Replacing a Library Controller Card” on page 10-8), 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 being read.

4.If the labels are still not being 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 on the Operator Control Panel (Service → Library Verify) which includes a drive (or drives) read/write diagnostic, the following procedures are suggested to help isolate the failure to properly establish connectivity to the Host Bus Adapter (HBA).

1.Use the utility, ITDT, 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 has the ability to scan and find all 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 “Using the ITDT Firmware Update, Dump Retrieval and Drive Test Tool” on page 9-5for a brief description of ITDT and instructions on how to download the tool from the web.

2.If ITDT successfully locates the LTO device(s), 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 and/or updates (dll’s, PTF’s, etc.) have been installed and applied.

Identifying a Suspect Cartridge

The amber Attention LED will be lit on the front panel of a library when there has been a failure that indicates a piece of media is bad, marginal, or invalid. It will be cleared when all invalid cartridges have been exported from the library. The amber LED may also be lit because a power supply, or a power supply fan is failing.
