Cannot load exchanger medium (System error)

Hi all,

I am using 9.09 DP and Linux on the CM. Last few weeks ago til now I meet the error below,. Sometimes I have changed the medium and backup back to work normally, but not all the times it's success with this way. Does this error come from hardware issue?

Hi Silva,

Besides "System error" you're not seeing anything more specific?

I would suggest to generate debugs of this and open a support case. The UMA debugs should tell us what exactly is failing here.

I would also try to run uma standalone and check whether the same move operation is working or not.

Re: Cannot load exchanger medium (System error)

Hi @Silva,

I had similar issues years ago. It was on a MSL4048 where the changer device was not responding after loading/unloading media into/from the tape library.

It turned out that the front panel of the MSL4048 blocked the changer device. If you have a MSL G3 aka MSL2024/4048/8096 you should upgrade to the latest firmware and make sure to close all menus on the front panel when finished.

Regards,
