Hello,

I have 2 LVD SCSI adapter on 2 different servers and I would like determine what are the SCSI ID.

LVD SCSI Adapters are installed in slot (0/8/0) 10 and 11 (0/12/0)

ID's SCSI for host1 :

ID's SCSI for host2 :

Thanks.

Host1:

ctl 14 0/8/0/1.7.0 sctl CLAIMED DEVICE Initiator
/dev/rscsi/c7t7d0

ID 7

Host2:

ctl 5 0/8/0/1.7.0 sctl CLAIMED DEVICE Initiator
/dev/rscsi/c5t7d0

ID 7

ctl 10 0/12/0/1.6.0 sctl CLAIMED DEVICE Initiator
/dev/rscsi/c7t6d0

ID 6

Looks like the disk system A6491A is shared between the 2 servers, one HBA has ID 6, the other ID 7 - looks good.

Hello Olivia,

The HOST HBA/ SCSI controller always has the scsi id of 7 by default.

I find that you have connected a ds2300 to the slots...which reserve the id 7 for the HOST.

check the manual of ds2300 user guide

pg 88 for more information
