Dell MD3220 – reset preferred controller module

Recently, id resetted the controller modules of the Dell MD3220 Storage Array while troubleshooting some strange events (it didnt change anything, ok its not a windows system ;D ).

After this, the virtual disks changed their path to the second controller. Ok, its not “mission critical”, but you always get the message that the virtual disks are not one the preferred path.

So, as described in my last post, this is also one of the operations that cant be made with MD Storage Manager.

This command will help: smcli.exe your-md-dns-name-or-ip -c "reset storageArray virtualDiskDistribution;"

Ps: Here you can find the Command Line Guide for SMCLI:
