How to troubleshoot if the HP E Series library does not power on?
If the HP Control Unit library doesn't power on, verify that: the power cord is connected to a grounded electrical outlet; each PDU power switch is on, as well as the switch on the power strips; power cords from PDU power strips are installed and seated; and the library main power switch is on.
What to do if the HP Control Unit library or tape drives are not detected by the Interface Manager or Command View TL software?
If the HP Control Unit library or tape drives are not detected by the Interface Manager or Command View TL software, check the following: - Cable connections. - Cabling, ensuring all radial bends do not exceed a 2-inch diameter. - Verify that the drives and library are powered on and can be seen by the OCP and hosts. - Log files for network problems. - Ensure that the interface controllers are powered on and ready.
Why host computer cannot communicate with the HP Control Unit library?
If the host computer cannot communicate with the HP Control Unit library, verify that the host computer was added to the Secure Manager using the Command View TL software and was given access to library components. Also, verify there is power to library components, check cable connections and termination, verify that the interface controller link LEDs show activity, and restart the host and the library.
What to do if one or more tape drives fail during startup of the HP E Series Control Unit?
If one or more tape drives fail during startup of the HP Control Unit, verify the OCP does not show the drive power as off, check the power supply indicator for power to that module, ensure the drive is properly cabled and ready, check the link indicators on the e2400-FC 2G interface controllers for a valid link to the drives, check whether the FAULT indicator is lit on the back of the drive (diagnose the problem if it is), and ensure the tape drive has the appropriate firmware.
What to do if the OCP is blank on an HP E Series?
If the OCP (Operator Control Panel) on your HP Control Unit is blank, try the following: Touch the OCP to wake it from sleep mode, confirm that the power is on. You can also use Command View TL software or the Interface Manager CLI to check for errors.
What to do if the robot does not move at power on in HP E Series?
If the robot in your HP Control Unit does not move at power on, verify that all internal shipping restraints have been removed, check that the library front door is closed, and review the latest error messages in the critical and warning event logs to help decipher the message and determine the cause.
How to troubleshoot a bar code reader failure in an HP E Series?
If the bar code reader fails in your HP Control Unit, use the OCP to open the library doors and verify that nothing obstructs the reader or the robot. Also, verify that all tape cartridges are fully inserted into the storage slots and no tapes are lying on the library floor, check that approved bar code labels are being used and are correctly applied, and close the library doors to recalibrate the library.
What to do if a tape cartridge is reported not present in HP Control Unit?
If a tape cartridge is reported as not present in your HP Control Unit, verify that the designated cartridge is present and properly seated (ensure that the cartridge is completely unloaded for a tape drive), then retry the command. If the issue persists, perform an inventory by opening and closing the library doors.
What to do if the OCP does not respond to touch on an HP E Series?
If the OCP (Operator Control Panel) on your HP Control Unit does not respond to touch, verify that the Ethernet cable is properly connected between the library robotics controller PUBLIC port and the CASCADE port on the Interface Manager card. You can also use Command View TL or the Interface Manager CLI to check for errors on the OCP.
What to do when a move command fails in the HP Control Unit?
If a move command fails in your HP Control Unit, read the error message for detailed information, check the source and destination (the source should hold the cartridge to be moved; the destination should be empty), ensure that the picker is empty and that there are no obstructions, and retry the command.
