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 library controller card CRU (refer to
“Replacing a Library Controller Card” on page 10-11), 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 9-5 for 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 the 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.
Note: The amber LED may also be lit because a power supply, or a power supply
fan is failing. Refer to “Isolating a Power Supply Problem” on page 7-7.
1. Identify the media using 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:
a.
Using the web, select Manage Library > Move Media. If the cartridge is not
in an I/O Station slot, move the cartridge to an I/O Station slot.
b. Using the OCP, select Control > Open I/O Station.
