I have a machine with a 410Gb Hardware RAID concisting of 3 SCSI Hard Disk. I then have the OS drive (Fujitsu disk) which is another SCSI Disk that is not part of the RAID array. Lastly, I have a 120Gb Seagate SCSI Disk connected via LV\SCSI on a seperate cable that acts as a slave storage facility. I have a DVD drive connected via IDE.
I have a SCSI card for external SCSI devices that currently has nothing connected to it.
I want to determine which SCSI devices (cards, disks, RAIDs etc) have got which SCSI ID's assigned to them so that when I attach my next SCSI external device I know what ID to assign it with regards to the optimum assignment method of SCSI IDs (i.e. 7 being the highest priority usually given to the card, 6 the next highest, 5, 4, 3, 2, 1 0 then 15, 14, 9 and 8.
I want to ensure my OS disk, hardware RAID and their controllers have the highest priority ID's with the external card and external devices having the lowest priority.
I have used lsscsi which shows me the following :
[0:0:0:0] disk DELL RAID_410Gb V1.0 /dev/sda
[0:1:0:0] disk SEAGATE ST3146807LW DS09 -
[0:1:1:0] disk SEAGATE ST3146807LW DS09 -
[0:1:2:0] disk SEAGATE ST3146807LW DS09 -
[1:0:0:0] disk FUJITSU MAP3367NP 5605 /dev/sdb
[1:0:2:0] disk SEAGATE ST3146807LW DS04 /dev/sdc
[3:0:0:0] cd/dvd LITE-ON DVDRW SHM-165H6S HQSA /dev/scd0
but I don't really understand how the ID assignments are showing?
