Dear group,

I am confused and don't know where to look. Do I need to panic about
these warnings?

Thank you,

This is of no concern. My guess is you have an application which is
trying to read one of the EVPD SCSI inquiry pages and that page is not
applicable to the device.

Feel free to sleep at night.

:-) Thank you. I will try to check what went wrong, exactly.

Have a nice day,

Don't assume anything went wrong. It is perfectly normal and
acceptable for an application to do this. Sense data can be thought
of return codes. How else would an application know what the
capabilities are of a disk drive w/o asking it? It isn't as if it is
practical to maintain a huge database of disks along with valid
instruction sets, configurable parameters (mode pages), and
statistical pages (log pages).
