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
->
