FYI for anyone looking swap the to 8 SAS and 7 SATA connections on the backplane of full build HL15’s and still have “45Drives Disks” work in Cockpit/Houston. _Default setup is SATA only for slots 1-1 to 1-8 and SAS/SATA slots 1-9 to 1-15. Cables coming from the motherboard to the backplane are labeled A,B,C,D going right to left._ ```auto Motherboard ------------------------------------------------------ | 15 14 13 | 12 11 10 09 | 08 07 06 05 | 04 03 02 01 | | D | C | B | A | ------------------------------------------------------ Front Fans / Panel ``` **To satisfy my OCD and have connections in “order” …** 1. Swapped SATA cables A/B and SAS cables C/D on the motherboard 2. Plugged cables into the backplane from _left_ to right in order A,B,C,D ```auto Motherboard ------------------------------------------------------ | 15 14 13 | 12 11 10 09 | 08 07 06 05 | 04 03 02 01 | | A | B | C | D | ------------------------------------------------------ Front Fans / Panel ``` 1. Updated `/etc/vdev_id.conf` so that 1-1 to 1-8 references SAS device paths (`/dev/disk/by-path/pci-0000:19:00.0-sas-phy[0-8]-lun-0`) and 1-9 to 15 sata device paths (`/dev/disk/by-path/pci-0000:00:17.0-ata-[1-7]`) are listed in order like my file include below. > **/etc/vdev\_id.conf** > > ```auto > GNU nano 7.2 vdev_id.conf > # HL15 Full Build 8 SAS / 7 SATA Config > alias 1-1 /dev/disk/by-path/pci-0000:19:00.0-sas-phy0-lun-0 > alias 1-2 /dev/disk/by-path/pci-0000:19:00.0-sas-phy1-lun-0 > alias 1-3 /dev/disk/by-path/pci-0000:19:00.0-sas-phy2-lun-0 > alias 1-4 /dev/disk/by-path/pci-0000:19:00.0-sas-phy3-lun-0 > alias 1-5 /dev/disk/by-path/pci-0000:19:00.0-sas-phy4-lun-0 > alias 1-6 /dev/disk/by-path/pci-0000:19:00.0-sas-phy5-lun-0 > alias 1-7 /dev/disk/by-path/pci-0000:19:00.0-sas-phy6-lun-0 > alias 1-8 /dev/disk/by-path/pci-0000:19:00.0-sas-phy7-lun-0 > alias 1-9 /dev/disk/by-path/pci-0000:00:17.0-ata-1 > alias 1-10 /dev/disk/by-path/pci-0000:00:17.0-ata-2 > alias 1-11 /dev/disk/by-path/pci-0000:00:17.0-ata-3 > alias 1-12 /dev/disk/by-path/pci-0000:00:17.0-ata-4 > alias 1-13 /dev/disk/by-path/pci-0000:00:17.0-ata-5 > alias 1-14 /dev/disk/by-path/pci-0000:00:17.0-ata-6 > alias 1-15 /dev/disk/by-path/pci-0000:00:17.0-ata-7 > > # This file was generated using dalias (2.0.0) > #alias 1-1 /dev/disk/by-path/pci-0000:00:17.0-ata-1 > #alias 1-2 /dev/disk/by-path/pci-0000:00:17.0-ata-2 > #alias 1-3 /dev/disk/by-path/pci-0000:00:17.0-ata-3 > #alias 1-4 /dev/disk/by-path/pci-0000:00:17.0-ata-4 > #alias 1-5 /dev/disk/by-path/pci-0000:00:17.0-ata-5 > #alias 1-6 /dev/disk/by-path/pci-0000:00:17.0-ata-6 > #alias 1-7 /dev/disk/by-path/pci-0000:00:17.0-ata-7 > #alias 1-8 /dev/disk/by-path/pci-0000:00:17.0-ata-8 > #alias 1-9 /dev/disk/by-path/pci-0000:19:00.0-sas-phy0-lun-0 > #alias 1-10 /dev/disk/by-path/pci-0000:19:00.0-sas-phy1-lun-0 > #alias 1-11 /dev/disk/by-path/pci-0000:19:00.0-sas-phy2-lun-0 > #alias 1-12 /dev/disk/by-path/pci-0000:19:00.0-sas-phy3-lun-0 > #alias 1-13 /dev/disk/by-path/pci-0000:19:00.0-sas-phy4-lun-0 > #alias 1-14 /dev/disk/by-path/pci-0000:19:00.0-sas-phy5-lun-0 > #alias 1-15 /dev/disk/by-path/pci-0000:19:00.0-sas-phy6-lun-0 > > ``` 1. Reload cockpit via `systemctl restart cockpit` and 45Drive Disks module should be updated! ![image](https://forum.45homelab.com/uploads/default/original/1X/34cbac52690ae88980e3d6e95397592f4413537c.jpeg) ---

Correct - the 45Drives Disks Cockpit module only fully works 45Drives or 45HomeLab equipment. ---

And same would be true for the other cockpit modules labeled “45Drives” - 45Drives Motherboard and 45Drives System. ---

What @rymandle05 is correct, if you are planning on using Houston on non-45drives hardware you can uninstall the 45drives-hardware package which will remove those tabs form the UI
