IBM L2/3 specs

The operating system of choice for this paper was Windows 2003 Standard Edition. The blade server was located in slot 5 of the BladeCenter chassis. The slot number is used for when you are attempting to start a SOL session from the Management Module. To administer the Windows 2003 blade server through SOL:

1.Telnet to the Management Module and login with USERID and PASSW0RD.

2.At the <system> prompt type console -T blade[5].

3.At the <SAC> prompt type ? for a help menu.

Commands at the <SAC> prompt are for administration of the blade server itself. The blade server can be restarted, services can be started or shutdown, IP addresses can be changed, the kernel log can be dumped, and so forth. To see a normal Windows command prompt, do the following:

1.At the <SAC> prompt type cmd to make a new command channel and note the name that is shown.

2.Type ch and look for your channel name in the list and note the number under the # column.

3.Type ch -si 1 to open the channel command prompt (1 is an example, but if the above steps were followed exactly it should be the number for your channel).

4.Login to Windows as you normally would.

5.To return to the <SAC> prompt at anytime, type exit.

The Linux and AIX® the SOL sessions look the same as when using SSH to administer the blade server.
