Ever since changing to the lsi 9300-16i controller I have been plagued with disks dropping offline. Disks seem fine with smart reports. 

I have ordered new mini-sas cables thinking this is the only item related to all the drives that go offline, besides a bad controller. I have also ordered new drives in case these are deemed bad. 

I was running an extended smart on disk 14 when everything went tit's up. In the last week I have rebuilt disk 1 & 14 fours times, only to have them go offline in a day or so.

anything else others see in my diagnostics?  What steps next?

 

Update : Replaced cables and all has been working fine.

Do you have any suspicion it might be a counterfeit card? Have you verified the serial number with LSI?

Bought card from ALLHDD.com so not an ebay purchase. It was new in a sealed box along with a vacuum seal around card.  So I doubt counterfeit but will run serial  on LSI web. 

Any firmware updates available?

Updated the firmware to the latest after install.

Added the extra power to card from this thread

 

Is it advisable to shut server down and re set all cables. I have now 3 disks that are now in unassigned devices, so I can rebuild 2 and I will copy off the data on the 3rd, which is not a whole lot maybe 4TB. Would I shrink array and take the 3rd drive out and let the 2 other drives rebuild?

The reason for change to 9300-16i, what disk controller use before ?

 

You have one 9300 ? ( lspci show have two, but I assume should be one )

Forget it, 9300-16i have a PLX chip and two SAS3008 controller.

I had 2 HP220 controllers each handling 8 drives. Went with a single 16i so I could replace the 2 and use the  PCIe 3.0 x16 to gain parity check speed.

 

The 16i is actually 2 controllers on one card. Atleast that is what it showed when I flashed the newer firmware.

All disk drop or half, may be try only use 8 port of 9300 and reinsert HP220 for another disks.

I am running 12 disks off the 9300 and the other disks are running on the onboard sata. 

I was planning on inserting my old card again and seeing what happens.

Reinserted the HP220 and put 3 disks on that card and am now rebuilding disk 1. Disk 1 was reballed before the restart so I was expecting to rebuild. All other disks are online with are looking ok.

Suggest not use the port which have drop disk ( best could use one of the controller on 9300-16i ), this just test does one controller have problem or not.

 

After rebuild, I would put array in maintenance mode and perform parity check ( no correction ), this just make loading to controller, if disk show error or drop again, then you don't need rebuild any disk. Once load test pass, then start array as usual and test/monitor does everything normal.

I do have 1 disk on that side of the 9300-16i. That disk has not shown any signs of problems and the other 3 disks are on the HP220. I have a new set of mini sas cables coming which I suspect might be the problem. Atleast I am hoping instead on the card.

 

Question now remains is do I format the disk (1) that is rebuilding since it is showing no file system or let it rebuild?

Sure. HBA problem quite trouble. Two controller in one card also too hot.

Too bad, if emulate disk show unmountable, even rebuild won't fix this, waiting some expert jump in. ( don't perform format )

This is why I am leaning toward cancelling the Parity-Sync/Data-Rebuild and format , then rebuild.

You can format disk1 if no data on it, otherwise don't format it.

I stopped Parity-Sync/Data-Rebuild and went into maintenance mode and am checking using the xfs repair

 

Update XFS repair done and disk mounted once again and rebuilding now.
