Resolution
This sequence of errors suggests a problem below the OS layer, involving the hardware, firmware, or physical media. Please consider the following actions and contact your hardware and/or driver vendor for support.
Run Hardware Diagnostics:
Execute diagnostic tools provided by the server, HBA, and tape drive vendors to check for hardware faults.
Check Firmware Versions:
Ensure that the firmware for the HBA and the tape drive are updated to the latest versions recommended by the vendor.
Replace the Tape Media:
Attempt the write operation with a new or known-good tape cartridge to isolate whether the issue is related to a specific faulty tape.
Check Physical Connections:
Verify that the SAS or Fibre Channel cables between the tape drive and the server are securely connected and not damaged.
Contact Vendor Support:
If the issue persists after these checks, contact support for your hardware vendor (server, HBA, HPE Ultrium Tape Drive), providing the collected logs.
Root Cause
The fundamental cause of this issue is that a write I/O request sent to the tape drive is not completing within the expected time.
An application issues a write request to the tape drive (st device).
For some reason (e.g., a hardware malfunction, faulty media, or a firmware issue), the tape drive stops responding to the I/O request.
The kernel waits for a response, causing the process that issued the request to become blocked in the D (uninterruptible sleep) state. This appears as the task ... blocked message.
After a certain period, the HBA's smartpqi driver detects a command timeout and initiates an error recovery sequence. This includes aborting the command (TASK ABORT) and resetting the device.
Even after the device reset, the physical write operation fails, ultimately resulting in a Medium Error.
This sequence of events indicates that the OS is timing out while waiting for a response from the hardware, strongly suggesting the problem lies at the physical layer rather than with the OS or application.
