Re: Cannot open exchanger control device (Device type mismatch)

Is the library on random mode?
Is there an error code on the library?

Re: Cannot open exchanger control device (Device type mismatch)

I am not sure what you actually mean.But when the backup starts it gives a msg backup mode is changed to full.
Also there aer no errors displayed on the front panel of the library.

Re: Cannot open exchanger control device (Device type mismatch)

You can check the library mode by going into the OCP (operator control panel) press menu > Library options > scroll down - Library mode.
Anyway also attach a support ticket here usin library and tape tools.

Re: Cannot open exchanger control device (Device type mismatch)

The library is at a remote location and i am not able to access it.

Re: Cannot open exchanger control device (Device type mismatch)

If you are in a remote location, you can try the following steps.

You can use the Remote Management Interface of the MSL Library if its connected in Network.

Open a Internet Explorer window and type the IP Address of the MSL Library.

You will get the RMI and login to the Library with the username and password.

Then click on Configuration and then change the Library Mode to Random.
Click Save.

AJJ,

Start a commandline session and go to
"D:\Program Files\OmniBack\bin"

type:
devbra -a

You will see some output like this:

D:\Program Files\OmniBack\bin>devbra -a

===========================

The key thing here:

The path to the changer device (in above example scsi4:0:0:0) should be the same is an your backup specification.

Also note that your removable storage manager is currently controlling the media changer device. This can have some negative side effects. Best is to disable the RSM service and then reconfiure the library such that is access the changer device through the SCSI path.

Hope this helps you on your way.
