Hi,

Which version of firmware is on the LTO? Also which version of the LTFS you are using?

For LTFS to work, you need to have the LTFS enable firmware.

You don't say which HBA you are using. The P212/ZM Smart Array controller is not supported with LTFS and does not work with LTFS. You must have a P212/256 or some other controller.

Re: Ultrium LTO 3280 SAS

The controller information doesn't say which specific P410i you are using. I went and checked that controller and the base version of the P410i is a zero memory and will have the same limitation as the P212. You must have at least a 256MB cache.

The information you post just listed several of the variations of the P410i and didn't say which one you have. You can check during boot up - it will list the size of the cache memory if one is installed.

You should also be using at least version 1.01 of the LTFS driver.
