We are facing some problem with IBM Storage DS3512 regarding Preferred Path issue on one of our client.
DS3512 with 3 expansion units and SAS connectivity , only two host connected having linux 5.2 64bit,
One host accessing 2 partitions and working fine but 2nd one is accessing 5 partitions that is creating problem of Preferred Path issue.
I have upgraded firmware of Storage, Expansions, and also updated RDAC drivers.
Cabling is Controller-A to Switch1 one and Controller-B to Switch2
