Just curious, willing to learn. Can someone please explain

Can someone please explain what these values mean?

I found them under the Devices listing. Especially the underlined values.

 

parity device: pci-0000:00:1f.2-scsi-2:0:0:0 host6 (sdk) SAMSUNG_HD204UI_S2H7J1BB227793

disk1 device: pci-0000:00:1f.2-scsi-0:0:0:0 host4 (sdf) SAMSUNG_HD204UI_S2H7J1BB228174

disk2 device: pci-0000:00:1f.2-scsi-1:0:0:0 host5 (sdj) SAMSUNG_HD204UI_S2H7J1BB228170

disk3 device: pci-0000:00:1f.2-scsi-3:0:0:0 host7 (sdl) SAMSUNG_HD103UJ_S13PJDWQC45118

disk4 device: pci-0000:02:00.0-scsi-0:0:0:0 host0 (sda) SAMSUNG_HD103UI_S1LMJ1CQC06364

disk5 device: pci-0000:02:00.0-scsi-0:1:0:0 host0 (sdb) SAMSUNG_HD103UJ_S13PJDWQ308116

cache device: pci-0000:02:00.0-scsi-0:2:0:0 host0 (sdc) SAMSUNG_HD103UJ_S13PJDWQC45101

I am going to assume you are running 4.7.

 

Those are just the assignments of your data drives to the "slots" as determined by unRAID.  unRAID 5.0 no longer uses this "slots" concept and does everything based off of serial number of the HDD.

Thank you prostuff1.

 

Can you please explain a bit more?

 

disk1 device seems clear but all those numbers beginning with pci..... and host. Can you please explain a bit more? Can you, when seeing this list see which sata-interface is located on the motherboard and which one on the esata port?

And yes i am on unraid 4.7.

 

Thanks in advance.

Without you giving us much info to go on I will only make some educated guesses

 

Looks like your board probably has 6 SATA ports on it.  4 are controlled by one controller and the other 2 are on the same controller as the eSATA port.  It looks like there are 2 different controllers at play here, but other than that there is not a lot to see.

 

 

The pci-####### stuff does not really mean anything, even to me.  The only people that might have some insight would be people that know about the kernel.

The parity, diskN, and Cache device labels are unRAID assigned, for the user.  The hostN labels are provided by unRAID for spindown control, and are user-editable in the web interface.  The pci-0000:* device symbols are a Linux kernel thing, somewhat analogous to Windows CLSID's for devices and busses.  They are arbitrarily assigned by the kernel and kernel modules during initial setup by the kernel, and you have no control over it.  The various system module authors have decided how they will number their devices and sub-devices etc.

 

Above, you have 4 drives on a motherboard controller pci-0000:00:1f.2.  You also have 3 drives on a card designated as pci-0000:02:00.0.  The initial pci part of the symbol indicates these are assigned within the PCI system of devices, as opposed to RAM or CPU or other sub-systems.

Thank you RobJ for this explanation. You are right with this. The 4 drives on the motherboard controller are inside an EX490 tower the other 3 drives are inside an Sans Digital TR5m-B that is connected to the e-SATA-port of the EX490.
