I've recently encountered a frustrating, and probably simple, problem. I've
recently become the administrator of a PowerEdge 2650 server setup with a hard
RAID and I need to determine the number of hard disks on the raid and the sizes
of each. I've searched far and wide and can't seem to come up with a solution
or a quick way of finding this information. It's not feasible to look at the
actual hardware, as the machine offers email service to several thousand people,
and I'd like to avoid any sort of downtime. Here is some information that may
be useful:
Redhat Linux 7.1
/var/log/dmesg:

My apologies for the overwhelming amount of information and the trivial nature
of this question. Any help or pointers would be greatly appreciated! Thanks in
advance!
