On an older server the customer replaced a SAS drive.
I see it as /dev/sg11, but not yes as /dev/sdX, it is not visible in "lsblk" Back then with an installed Suse Linux, I had some GUI tool to create a VD on top of the physical drive and "enable" it ... I am searching how to achieve that in gentoo now. - # lsscsi [1:1:0:0] disk TOSHIBA MG04SCA20EE 0104 - I *assume* that it is connected to the RAID bus controller: Adaptec AAC-RAID but when I run "arcconf" I only get segfaults. # lspci 00:00.0 Host bridge: Intel Corporation 5000P Chipset Memory Controller Hub (rev b1) 00:02.0 PCI bridge: Intel Corporation 5000 Series Chipset PCI Express x8 Port 2-3 (rev b1) 00:04.0 PCI bridge: Intel Corporation 5000 Series Chipset PCI Express x8 Port 4-5 (rev b1) 00:06.0 PCI bridge: Intel Corporation 5000 Series Chipset PCI Express x8 Port 6-7 (rev b1) 00:08.0 System peripheral: Intel Corporation 5000 Series Chipset DMA Engine (rev b1) 00:10.0 Host bridge: Intel Corporation 5000 Series Chipset FSB Registers (rev b1) 00:10.1 Host bridge: Intel Corporation 5000 Series Chipset FSB Registers (rev b1) 00:10.2 Host bridge: Intel Corporation 5000 Series Chipset FSB Registers (rev b1) 00:11.0 Host bridge: Intel Corporation 5000 Series Chipset Reserved Registers (rev b1) 00:13.0 Host bridge: Intel Corporation 5000 Series Chipset Reserved Registers (rev b1) 00:15.0 Host bridge: Intel Corporation 5000 Series Chipset FBD Registers (rev b1) 00:16.0 Host bridge: Intel Corporation 5000 Series Chipset FBD Registers (rev b1) 00:1c.0 PCI bridge: Intel Corporation 631xESB/632xESB/3100 Chipset PCI Express Root Port 1 (rev 09) 00:1d.0 USB controller: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #1 (rev 09) 00:1d.1 USB controller: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #2 (rev 09) 00:1d.2 USB controller: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #3 (rev 09) 00:1d.7 USB controller: Intel Corporation 631xESB/632xESB/3100 Chipset EHCI USB2 Controller (rev 09) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev d9) 00:1f.0 ISA bridge: Intel Corporation 631xESB/632xESB/3100 Chipset LPC Interface Controller (rev 09) 00:1f.1 IDE interface: Intel Corporation 631xESB/632xESB IDE Controller (rev 09) 00:1f.3 SMBus: Intel Corporation 631xESB/632xESB/3100 Chipset SMBus Controller (rev 09) 01:00.0 PCI bridge: Intel Corporation 6311ESB/6321ESB PCI Express Upstream Port (rev 01) 01:00.3 PCI bridge: Intel Corporation 6311ESB/6321ESB PCI Express to PCI-X Bridge (rev 01) 02:00.0 PCI bridge: Intel Corporation 6311ESB/6321ESB PCI Express Downstream Port E1 (rev 01) 02:02.0 PCI bridge: Intel Corporation 6311ESB/6321ESB PCI Express Downstream Port E3 (rev 01) 03:00.0 PCI bridge: Intel Corporation 6700PXH PCI Express-to-PCI Bridge A (rev 09) 03:00.2 PCI bridge: Intel Corporation 6700PXH PCI Express-to-PCI Bridge B (rev 09) 06:00.0 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01) 06:00.1 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01) 07:01.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 08) 09:00.0 PCI bridge: Intel Corporation 80333 Segment-A PCIe Express to PCI-X bridge 09:00.2 PCI bridge: Intel Corporation 80333 Segment-B PCIe Express to PCI-X bridge 0a:0e.0 RAID bus controller: Adaptec AAC-RAID 0d:01.0 VGA compatible controller: Advanced Micro Devices, Inc.
