Q:

Best way to figure out which dev entry a drive maps to?

Have multiple drives on the server. I'm booting up to rescue mode and seems like the /dev/sd* do not map in the same sequence as normal.
What is the best way to figure out which drive is which? Perhaps just giving me the manufacture information or by connection?

A:

There are a lot of different approaches.  First you can try mounting the various /dev/sd* devices and looking at their contents.
If you're using LVM, the volumes should appear in /dev/vgname/lvname no matter what /dev/sd* devices they come up as.  Same for software raid devices (MD).
If your disks have labels, there is probably a map in /dev/disk/by-label.
If you keep your fstab by UUID (not a bad idea), there's a map in /dev/disk/by-uuid/.
