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 David Original Message ---------------------- From: "David Proffitt" <david.proffitt@itn.co.uk> Date: Thu, 4 Apr 2002 17:17:18 +0100 To: sunmanagers@sunmanagers.org 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?
