Question sdX to mount point mapping

OS: Solaris

When I look at my I/O distribution on a server using iostat, the devices report as sdX where x is a number like 0, 32, 128, etc. While I can guess which device maps to which mount point, is there any way I can definitely determine which sdX points to which mount point?

In sdX, the X means the device's instance id.

On simple once controller systems, you can pretty much call the instance ID the SCSI target ID I think.

For example, sd6 is usually the CDROM drive which is commonly found on ID6.

That was a simple way if you don't have a lot of controllers.

Otherwise, you can use "sysdef -d" or "prtconf -v". It will give you a heirarchical breakdown of what drivers are attached to what devices, etc. And you can make deteminations of which controllers and which targets they are that way.

It's ugly, I know, but it's the only way I can think of doing what you want. I've had to do this on some E6500 machines before, and let me tell you it was not pretty.

Oops... forgot to mention that once you determine what controller and target the drives are, you can use the df command or look at the /etc/vfstab file to see what is mounted where.

If you are using Veritas Volume Manager or Solstice DiskSuite, then you would use those utilities to find out what file system a particular disk belongs to.
