Issues Migrating to DS4246 (6.11.1)

[jarkle]

I purchased a DS4246 and a QSFP card to migrate my 17 disks to. I first moved one disk which was recognized then I added 6 more and they were all recognized. I then migrated the remaining 10 and removed the old LSI cards I was using previously. Now there are no disks recognized.. 😞 

 

Anyone able to discern anything from my diag?

Lots of errors with the controller, though cannot say the controller is the problem, do you have an LSI HBA you could try with?

I have the old LSI cards I removed but that would require different cables.

 

Would you recommend using LSI cards instead of a netapp card?

Yes, those have been known to cause some issues in the past, and the driver is likely not as stable and widely used as the LSI driver.

Could you recommend a card and the necessary cable(s)?

[JorgeB]

LSI 9200-8e or 9300-8e or similar, with a QSFP to SFF-8088 cable for the former and QSFP to SFF-8644 cable for the latter, but like mentioned cannot say the current controller is the problem, just that an LSI usually works better.

[jarkle]

Understood. It's worth a shot.

 

Will the 9300-8e support the entire shelf or would I need two of them?

 

I would just need a single QSFP to SFF-8644 cable?

[JorgeB]

Yes, you just need one LSI with a single cable.

[jarkle]

Copy that. Any other troubleshooting I can do with the NetApp card?

[JorgeB]

Not familiar with those controllers, but you could try removing some disks and testing different slots, i.e. are half of the disks detected in the first slots, if yes are those same disks detected using different slots, etc

It appears that the netapp card or shelf does not like mixing drive sizes..

 

More specifically if I try and mix drives <=4TB with drives >4TB things start not being recognized.

 

I was able to add 2-2TB, 4-4TB and 1-8TB to the shelf and all were recognized by Unraid. If I added one more 8TB then one of the 4TB would drop out and the second 8TB would be recognized.

 

For now since 8TB is the most I have of a size with a count of 9 I stuck all those into the DS4246 with my only 10TB and they all recognize perfectly.

 

Then for the 2TB (2) and 4TB (4) drives I connected back to my old LSI.

 

At first I had the old LSI in the top x16 slot and that caused the drives in the DS4246 to not be recognized by Unraid.

 

I swapped the NetApp card into the top x16 slot and the LSI into the second x16 slot and boom, all drives are recognized.

 

Hopefully the 9200-8e I have on order will make this issue go away so I can move ALL the drives into the DS..

Strange, I don't have experience with those enclosures but don't remember anyone posting about a similar issue, hopefully the LSI helps.
