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?
When you are getting the degraded wide port error the MD is unable to connect to a certain path. So what I would do is that if you are not at the latest version of firmware 07.35.39.64 then I would upgrade to that version. If you are at that version of firmware than I would also check all iSCSI connections to make sure that they are showing as logged in.
If you have never upgraded the firmware here is how to do so.
This update process will take 60-90 minutes but will vary depending on how long the reboots take to complete.
Please let us know if you have any other questions.
