I'm happy to report that the issue is now resolved.  The issue was that the SAS Interface card in one of the two connected VMWare host servers had failed.  To identify which one, if you look at my server connection image it was slot 6 of "Server 1".   [IMAGE]   To summarize for anyone who is running into this issue in the future -1. check the cable connections - if those are ok... 2. swap cables around to see if you can identify a bad cable - if those are ok... 3. If you have a DRAC, login and check the storage interfaces.  This is what identified the issue for me - in one of the servers (server 1), only 1 of the 2 storage interfaces was still showing, in our other server (server 2) both interfaces were showing. In hindsight, I should have done step 3 above first so I wouldn't have had to contact the remote hands team to check cables when it could have been seen if I just looked in the right place. Hope this helps anyone in the future - thanks again to the Dell team for your help in resolving this, we now have a GREEN status for this unit/system.  Cheers!
Greetings, I'm hoping someone can assist us.  Background: We have a Dell PowerVault 3400 with 6x 1.92 Tb SSD drives and two RAID Controller Modules.  The RAID Controller Module Firmware is 08.25.14.60.  It repeatedly will switch its status to "Storage Array Needs Attention".  When clicking the link to see the details in the Recovery Guru, the summary states it is "Virtual Disk Not On Preferred Path". I followed this thread [URL] and followed the advice presented there: I've verified the controller firmware is up to date and updated the drive firmware.  Issue: Below is the main issue I'm asking for assistance on... I can clear the error temporarily by going to Storage | Virtual Disk | Advanced | Redistribute Virtual Disks and the error will clear. The error will return within a couple hours.  Here is an example from yesterday where I redistributed the disks (starting with event sequence number 3737 [NAME]:14:31 PM and it returning with sequence number 3749 [NAME]:06:33 PM) Below I have the Event Log Entries I think have details that may be helpful.  What other information can I provide to paint a clear picture of the issue? Thanks in advance!
