Semi Missing Drive....

[RichDominelli]

Still in my trial period.

I have 3 10TB drive a WD purple which I set for parity and 2 identitcal drives.

All are connected to a dedicated sata 3 controller.

I see all 3 in the tools - hardware

[7:0:0:0]disk ATA WDC WD102PURZ-85 0A82 /dev/sdb 10.0TB

[8:0:0:0]disk ATA OOS10000G OOS1 /dev/sdc 10.0TB

[10:0:0:0]disk ATA OOS10000G OOS1 /dev/sdd 10.0TB

 

But only 1 of the bottom 2 drive appears in the array configuration and I cannot figure out why?

Go to Tools - Diagnostics and attach the complete Diagnostics ZIP file to your NEXT post in this thread.

Where did you get these? They don't appear to have unique serial numbers. Each disk is identified by its serial number so Unraid can't keep track of them separately.

Ah the joy of ebay drives... yeah I see a few other folks out there with this issue now that I know what to look for.  Is there any way of artificially setting the serial number? One of the other threads suggested "For me the solution was to enable "list IOMMU" in the motherboard BIOS." so I will check that as well.

Sure, but last I heard the software to do it was in the 10's of 1000's of USD.

Are you sure this controller is using IT mode?

05:00.0 SCSI storage controller [0100]: Broadcom / LSI SAS1068E PCI-Express Fusion-MPT SAS [1000:0058] (rev 08)
    Subsystem: Dell SAS 6/iR Integrated Workstations RAID Controller [1028:021d]

 

Also, Marvell controllers NOT recommended

04:00.0 SATA controller [0106]: Marvell Technology Group Ltd. 88SE9215 PCIe 2.0 x1 4-port SATA 6 Gb/s Controller [1b4b:9215] (rev 11)

Everything is on the Marvell controller.  Whats a better brand?
