That disagrees with my experience. The SPA

Just trying to avoid confusion.
I now have already have five different numbering scemes:
ID2=sd2=dk0=component0=column 1.
Fortunately two of then coincide and so I have three of them
only differing by a

For real SCSI - ie, non-SAS - it's actually necessary; the protocols
used for initiators and targets to speak with one another require a
line for the initiator as well as for the target. But the host is
usually ID 7.

What I would like to change are the SCSI target numbers. I wrote:

but I would like those targets to be 0..6.

I have a (mpt) SAS with seven discs connected.
The discs attach as sd0..sd6, but the SCSI target numbers are 0..5 and 7.
It appears to me that someone is skippig ID 6 for the controller.
It doesn't hurt too much, but it took me a while to find out why detaching
targets 2, 3, 4 and 5 worked and 6 d
