So, one possible scenario: You power up the machine for the first time, you
enter ILOM console, you create username & password & static IP address. From
now on, you're able to get the remote console, awesome, great. No need for
ipmi-tool in the OS.
Another scenario, that I encounter just as often: You inherit some system from
the previous admin. They didn't set up IPMI or ILOM. They installed ESXi, and
now the only thing you can do is power off the system to do it.
But in the situation where I inherit a Linux / Solaris machine from a previous
admin who didn't config ipmi... I don't need to power down. I can config the
ipmi via ipmi-tools.
Going a little further down these trails...
If you have a basic IPMI device, then all it does is *true* ipmi, which is a
standard protocol. You have to send it ipmi signals via the ipmi-tool command
on your laptop (or another server). It doesn't use SSL; it uses either no
encryption, or a preshared key. The preshared key is a random HEX 20 character
long string. If you configure that at the boot time (as in the first situation
mentioned above) then you have to type in at the physical console at first
boot: new username, new password, new static IP address etc, and the new
encryption key. But if you're running a normal OS, you can skip all that, boot
the new OS, and paste all that stuff in via ssh, using the local ipmi-tool to
config the local ipmi device.
If you have a newer, more powerful ILOM device, then you probably only need to
assign an IP address to the ilom. Then you can browse to it via https and do
whatever else you need to do.
Long story short, "Depends." ;-)
