Re: [smartmontools-support] PERC/MegaRAID bay to dev association

[Artem B. <ap...@ng...>]

dmesg | grep "4:2:0:0:", probably the same is possible with scsi tools.

[    2.815139] scsi 4:2:0:0: Direct-Access     LSI      MR9280-4i4e      2.13

TB/12.7 TiB)
[    2.822725] sd 4:2:0:0: Attached scsi generic sg0 type 0

4:2:0:0 - LD0
4:2:1:0 - LD1
4:2:1:0 - LD2

Then you may find bay number with "MegaCli64 -ldpdinfo -a0", where Slot number 
is bay number.

Enclosure Device ID: 24
Slot Number: 0
Drive's postion: DiskGroup: 1, Span: 6, Arm: 0
Enclosure position: 0
Device Id: 8
