could someone help me out? I have this software-raid:
md3 : active raid6 sdi1[8] sdh1[6] sdg1[4] sdf1[5] sde1[3] sdd1[2] sdc1[0] 4391334912 blocks level 6, 64k chunk, algorithm 2 [8/6] [U_UUUUU_] [====>................] recovery = 22.8% (167386900/731889152) finish=196.6min speed=47837K/sec and I would like to know which hard disk (vendor, serial) each /dev/sdX is. (I have to tell the remote admin which physical disk to remove from the server, and there are disks in the server which aren't part of the RAID yet) Found sg_map and sg_scan: # sg_map /dev/sg0 /dev/nst0 /dev/sg1 /dev/sg2 /dev/sda /dev/sg3 /dev/sdb /dev/sg4 /dev/sdc /dev/sg5 /dev/sdd /dev/sg6 /dev/sde /dev/sg7 /dev/sdf /dev/sg8 /dev/sdg /dev/sg9 /dev/sdh /dev/sg10 /dev/sdi /dev/sg11 /dev/sg12 /dev/sg13 /dev/sg14 /dev/sg15 /dev/sg16 /dev/sg17 /dev/sg18 /dev/sg19 /dev/sg20 /dev/sg21 -- The crux: It seems I get two sg-devices per physical disk: sda = sg2 = sg11 ... sg11 is shown as SEAGATE, sg2 as ICP (tried -d scsi and -d sat as well) and I only get useful info from the sg-devices >10 -> # smartctl -d auto -i /dev/sg11 smartctl 6.4 2015-06-04 r4109 [x86_64-linux-3.18.11-gentoo-smp] (local build) Copyright (C) 2002-15, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Vendor: SEAGATE Product: ST373455SS Revision: 0002 User Capacity: 73,407,868,928 bytes [73.4 GB] Logical block size: 512 bytes Rotation Rate: 15015 rpm Logical Unit id: 0x5000c50002448407 Serial number: 3LQ11JWH00009748U10J Device type: disk Transport protocol: SAS (SPL-3) Local Time is: Wed Mar 1 15:51:28 2017 CET SMART support is: Available - device has SMART capability.
