In-Depth Information
The remote console is an easy way to get access to the server console, to configure a server, or to diagnose issues,
if remote connectivity to the server itself is not available. Once the remote console is launched, you see a login prompt
similar to what you see when you log in to a Unix machine. This allows you to log in to the server from the console.
The remote console provides access to the console messages and allows users to log in to the system. Each server
node (SN) has its own ILOM, so in the context of an ODA, there are two ILOMs. This is very important because each
physical server in the ODA has its own ILOM that has to be used for managing and maintaining that physical server.
Integrated Shell
The ILOM is also accessible via a shell that is integrated into the service processor. That shell is a convenient way to
access and operate an ILOM. The ILOM shell can be accessed via various methods, as follows:
•
The NET MGT port on the server node (serial connection)
•
The server node using ipmitool over TCP
•
TCP to SSH (Secure Shell) directly into the ILOM
•
IPMITool over LAN, locally or from any device that supports ipmitool
The integrated shell is used to configure the ILOM for the first time. It can be used by the datacenter team to
prepare the ODA for configuration. The integrated shell is also used to perform basic functions like ILOM password
changes, checking for system faults, gaining access to the console, and so forth.
The integrated shell is accessible via the
ipmitool
command. It can also be accessed on the server nodes
and remotely using ipmitool with the lanplus protocol. The ipmitool can be accessed via the host for which the SP
manages the hardware (as root; the IPMI device in Linux only allows root access). For example:
# ipmitool sunoem cli
Connected. Use ^D to exit.
Another way to connect to the SP is via the lanplus protocol. This approach can be used on a remote machine
where ipmitool is installed. Here's an example:
[root@mxt101 ~]# ipmitool -I lanplus -H <ilom hostname/address> -U <ilom username>
-P <ilom user's password> sunoem cli
Connected. Use ^D to exit.

The ILOM can be accessed remotely via native SSH as well. Here's how that is done:
$ ssh <ilom username>@<ilom hostname/address>

The ILOM integrated shell provides a pretty rich command set and allows you to perform a variety of tasks
directly from the interface itself. Table

lists some of the key commands and how they can be accessed.
