138 HP StorageWorks MSL5000 and MSL6000 Series Tape Libraries User Guide
Identifying Platform Problems
An incorrect installation or configuration can cause platform problems. In this
case, the library appears to be operating normally, but no data can be
interchanged, or performance is poor. You also might or might not get an error
code on the graphical user interface (GUI) touch screen. To identify an error
caused by this type of problem, check your installation and configuration setup.
See Chapter 7, “Installation”, beginning on page 39 for information on how to
correctly install and configure the library.
General drive errors usually result from a miscommunication between a library
processor and a tape drive processor, drive and tape interaction issues, or a
mechanical malfunction within the library. Both platform problems and general
tape drive errors display an error message and a Fault Symptom Code (FSC) on
the GUI touch screen. Use an FSC to report errors to your authorized service
provider, or in some cases, to determine a recovery procedure.
The library depends on several other components to operate correctly. Errors that
seem to be caused by the library often are a result of issues on the host, the
network cabling, or with the application software. When troubleshooting the
library, begin ruling out these components.
Your application software may need to be reconfigured or, in some cases,
reinstalled after you have installed additional drives or slots into the library.
Changing the number of magazines, number of reserved slots, or changing
between DLT and Ultrium magazines will also require changes to the software.
Some application software may require the purchase of additional add-on
components and/or licenses when increasing the number of storage slots or drives.
Contact your application software provider for more information, or if newly
installed storage slots are drives are not recognized by your application software.
Note: The library numbers drives and slots beginning with 0. Your software
application may number these items beginning with 1. Be aware of this difference in
numbering when troubleshooting the library.
