hp Autoloader 1/9 Firmware upgrade fails

[like-a-mike]

Hy all
I tried to upgrade firmware on my C7145-9000 autoloader. All the services accessing the library were turned off but the firmware upgrase done with LTT got stuck and failed.

All the tests on the library itself went allright (Recalibration, Inventory) but the drive cannot be brought online again. The yellow indicator on the management card is on and the yellow lamp on the drive is flashing. How can I downgrade the firmware again to get the library running? LTT tools downgrade fails with the same error...

Any help would highly be appreciated.

Best regards, Markus.

first step would be to investigate why the device is not seen on the library controller.
But anyway, if you want to downgrade the FW of the drive and the library is preventing it because of the error, I suggest you to disconnect the interconnect scsi cable with the robotic controller, and to connect just the drive with terminator to the host, and flash the firmware.

Thanks Marino

I've connected the drive directly to SCSI, first downgraded the drive's FW and then upgraded it to current version.
Now the autoloader recognises the drive again.
