ASMI - Advanced System Management Interface

Every firmware service processor on a Power5 box has 2 Ethernet interfaces used for connection to the Hardware Management Console (HMC). Immediately after the power cord is connected to the p5 system, service processor sends a DHCP request through both interfaces. If no DHCP adress is received it falls back to the default adress:

  • HMC1 Port: 192.168.2.147 / 255.255.255.0
  • HMC2 Port: 192.168.3.147 / 255.255.255.0

You can connect to ASMI webinterface through the browser.

See http://publib.boulder.ibm.com/infocenter/eserver/v1r3s/index.jsp?topic=/iphbp/kickoff.htm for more information

How do determine FSP IP adress

If the default IPs above are not accessible and you do not have access to any DHCPd logs which may have provided an adress you can use following procedure to determine the adress through 3 white buttons at the operation panel below the led:

  1. Select function 02
  2. Change "N" to "M" (for manual)
  3. Select function 30
  4. Change "**" to "00" and press Enter
  5. See the adress of HMC1 at "00" and HMC2 at "01"
  6. Select function 02
  7. Change "M" back to "N"

Connection to ASMI through serial cable

Service Processor FSP is also accessible through serial line connection. See ftp://www6.software.ibm.com/software/developer/library/l-pow-opsetup.pdf for detailed settings.

This connection is only active if the box is not currently connected to HMC or was connected to it in the last 14 days.
If you see HMC=1 or HMC=0 on the LED screen you will not be able to get serial connection. You can reset the service processor and make it forget its HMC connection.

See http://publib.boulder.ibm.com/infocenter/eserver/v1r3s/index.jsp?topic=/iphby/ascii.htm for more information.

Disconnecting an HMC

In order to get serial access to the operating system you may need to disconnect the system from HMC and make it forget the HMC connection. This happens by default after 14 days, but if you do not like to wait so long follow the procedure described at http://publib.boulder.ibm.com/infocenter/eserver/v1r3s/index.jsp?topic=/iphbp/disconnecthmc.htm
