Hi,
We have an out of warranty MD3000i that has been running fine for years, but has recently begun throwing event code 1707, 1706 and 4011 errors every few months, and leaving us with Virtual Disk Not On Preferred Path showing in the MDM client. Previously we checked all cabling, redistributed the disks back to the preferred path and the error goes away for several weeks. Are we looking at a failing controller or could this be a network component issue?
