what policy sould i used to clear those errors in storage device (RR or RRWS)

[elementx]

1) Did it ever work?
2) If it did, and now it doesn't, what happened between these two events?

The reason for those recovery guru errors is that the E-Series SANtricity DSM is not installed / in-use. Instead, the Microsoft DSM is being used. You can find SANtricity DSM on the E-Series SANtricity OS Controller Software download page listed under Additional Downloads as "SANtricity Windows DSM".

Once you install the SANtricity DSM, the multipath driver error should automatically clear. Volume not on preferred path should also clear, but you may need to redistribute volumes manually: https://docs.netapp.com/us-en/e-series-santricity/sm-storage/redistribute-volumes.html
