[Update] I rebooted once more with a monitor attached.  I am getting a message about an l2/l3 cache issue.  this message itself is intermittent.  I do not consistently get this after rebooting a second time.  

 

 

First Post, Not a Linux guy

My issue is I have random drives that are showing up as missing after reboot.  Sometimes they reappear but it is really strange.  I have an old LSI card that has been rock solid for years 9300-16i.  I just added a new 9321-4i in JBOD mode.  This is when the issues with the first card(9300-16i) started to occur.  

I am not sure what to do to fix the issue.  

Any help would be appreciated.  Thanks

If possible before rebooting and while the issue is occurring and preferably with the array started
Go to Tools - Diagnostics and attach the complete Diagnostics ZIP file to your NEXT post in this thread.

Here are the diagnostics

I do see 16 drives on the HBA listed in the bios at boot up.  and the error about the l2/l3 cache is for the new card that has only two drives thus far that I haven't even incorporated into unraid.

Does the problem occur if you remove that?

I just removed and rebooted the problem still occurs

 

RAID controllers are not recommended for Unraid

ok i will just order a new HBA but the drives are still missing and now I only have the 9300 installed at this time.

I just move the drive to a different bay in the case and it now is seen by the unraid .  Im wondering if my sas plane is going dead.

Maybe an issue with power or data connection

yes i think it may be the sas plane.  I moved that entire row up to the top bays of my case and all the drive are recognized.  I looks like i will need a new case but norco is out of business.  guess I will be ebay shopping.
