SUMMARY: Backplane Disk Numbering

Thanks for all replies

There are some references in the E450 manuals and I have been sent a perl
script that can detect the mapping

format gives a list of disks numbered 0-9 but its apparently not guarenteed
that these are probed in the same order as they appear on the backplane

       5. c2t1d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>
                 /pci@6,4000/scsi@4/sd@1,0

A simple method is to generate activity on a given device and watch the access
lights

I'm off to the machine room to try these out

Subject: Backplane Disk Numbering

Hello

The disk in the slot labeled 5 on the backplane of an E450 is making a whining
noise

I'd like to add a new disk and move the contents of the suspect disk to it but
I need to work out the mount point

Is there a way of working out which slot on the SCSI backplane translates to
which block or raw device name?

Or of tieing the sd numbers returned by iostat to the physical device?

Thanks
