Hi Kinga Tanska,
My patch touches only the VMD controllers. I see that there are no
changes to VMD display in your output. My patch is only about VMD.
I guess that your issue is identical to what you already wrote to RAID
mailing list 5th of August. Correct? I cannot investigate this for
you, I am neither the author of the change, nor I have RST enterprise
RAID controller, sorry. Please contact the patch submitter/author.
Regards,
Oldrich.
