@alatteri

LTFS doesn't support Quantum LTO9 at all yet. Because I don't have any tape Quantum drives and I cannot try it at all.

Please add your drive in the table below, recompile and try it. And please give us the feedback it can work correctly. I will add it once you confirm it works.

Thank you. I will give it a try tomorrow. Is there any data I can provide you to incorporate into the code?

The LTFS said the tape drive below is not supported by LTFS30213I.

134a LTFS30213I Unsupported Drive 'QUANTUM ' / 'ULTRIUM-HH9     '.

You need to add the line below into quantum_supported_drives[] as the start point.

TAPEDRIVE( QUANTUM_VENDOR_ID, "ULTRIUM-HH9",  VENDOR_QUANTUM,   DRIVE_LTO9_HH, "[ULTRIUM-HH9]" ),  /* QUANTUM Ultrium Gen 9 Half-High */
alatteri commented 1 year ago

I've added this line: TAPEDRIVE( QUANTUM_VENDOR_ID, "ULTRIUM-HH9", VENDOR_QUANTUM, DRIVE_LTO9_HH, "[ULTRIUM-HH9]" ), /* QUANTUM Ultrium Gen 9 Half-High */ to quantum_tape.c , recompiled, installed and rebooted.

We are getting the following error from both a Quantum and IBM LTO-9.

Any update with lto9 and ltfs? Thanks.

rmocster commented 1 year ago

What is the hold up on the resolution of ltfs working with lto9 drive?

piste-jp commented 1 year ago

@alatteri

It looks the behavior of your HBA is incorrect against length-mismatch case. I guess the HBA doesn't support tape device correctly.

LTFS intensionally tries to read 80-byte length the ANSI label with under-length condition to confirm the HBA can handle it correctly or not. Because under-length condition sometimes happens in LTFS. (On the other hand, the length-mismatch condition never happens on disk access normally. )

piste-jp commented 1 year ago

@rmocster

At least, IBM LTO9 is already supported on the code and IBM confirms that on the IBM Spectrum Archive SDE.

This is the issue related HBA. This issue doesn't say LTFS doesn't support LTO9.

alatteri commented 1 year ago

Hi @piste-jp-ibm ,

Is there a recommended HBA list? I believe we are using an LSI.

I think it's not an objective of this project.

IBM is providing a list into SSIC. Please check this.

Can this be added to master code. It works perfectly when done manually.

The LTFS said the tape drive below is not supported by LTFS30213I.

  • Vendor ID: QUANTUM
  • Drive ID: ULTRIUM-HH9

We switched to an ATTO 12G SAS card, and no longer have any errors.
