Appendix E. Attaching Multiple pSeries 670s to One Hardware
Management Console
This appendix details how to attach multiple pSeries 670 servers to one HMC. The HMC might have an
8-port async adapter or a 128-port async adapter installed to allow multiple servers to connect. Procedures
for configuring both of the async adapters follow.
Installing the 8-Port async Adapter
The 8-port serial adapter is an option for the HMC. The 8-port serial adapter software is included in the
HMC's base software image. The 8-port async adapter must be configured by the service representative
when the HMC is installed. You must log in as root user to do these procedures.
For instructions on how to install and configure the 8-port adapter in the system with the HMC, see the
IBM Hardware Management Console for pSeries Installation and Operations Guide.
To install and configure the 8-port adapter in the system, do the following:
1. To access the HMC microcode maintenance function, obtain the password from software support and
log in as hscpe.
2. In the HMC Navigation area, click Problem Determination.
3. In the Contents area, click Microcode Maintenance. The User Authentication window opens.
4. Enter the HMC system unit's serial number and the password provided by software support. The
Microcode Maintenance Menu window opens.
5. Select Launch xterm shell to open a command prompt window.
6. Type su -, then log in as root user.
7. Type the following command to run the configuration utility: /usr/sbin/digiConf. You must provide the
following answers to the following questions:
a. Question: How many boards would you like to install? Answer: Enter the total number of 8-port
and/or 128-port async adapters in the system.
b. Question: Board #1. What type of board is this? ('L' for list) Answer: Use board type 15
c. Question: Do you want to set Altpin on this board? ('y' or 'n') Answer: No
If two 8-port adapters are installed in the system, you must provide the following answers to the
following questions:
a. Question: Board #2. What type of board is this? ('L' for list) Answer: Use board type 15
b. Question: Do you want to set Altpin on this board? ('y' or 'n') Answer: No
8. The HMC is configured. Reboot your PC to load the adapter device driver.
Connect the Serial Cables from the pSeries 670 to the 8-Port Async
Adapters
Up to two optional 8-port async adapters can be installed. The D-shell connector on the back of the
adapter attaches to the 8-port expansion cable. The cable is approximately 3 feet long, and on the other
end, has a slim box (8-1/2 inches x 3 inches x 1-1/2 inches) with 8 separate serial port connectors on it.
The cable is labeled ISA 8-Port Cable. Serial cables can be connected from any of the ports on the 8-port
expansion cable to the HMC1 ports on the managed systems.
If you are using a second, redundant HMC, connect cables from all the pSeries 670 HMC1 ports to the
8-port cable on the primary HMC, and connect all the pSeries 670 HMC2 ports to the 8-port cable on the
redundant HMC.
