Hardware Management Console (HMC)
When the machine types M/T 7040, M/T 7039, M/T 7038, and M/T 7028 are attached to a Cluster 1600, a Hardware Management Console (HMC) is required for the control of these machines. In a Cluster 1600, the HMC is attached to the control workstation (CWS) on the administrative LAN.
What is the HMC?
The IBM Hardware Management Console for pSeries provides a standard user interface for configuring and operating partitioned and SMP systems. The HMC supports the system with features that enable a system administrator to manage configuration and operation of partitions in a system, as well as to monitor the system for hardware problems. It consists of a 32-bit Intel-based desktop PC with a DVD-RAM drive.
What does the HMC do?
- Creates and maintains a multiple-partitioned environment
- Displays a virtual operating system session terminal for each partition
- Displays virtual operator panel values for each partition
- Detects, reports, and stores changes in hardware conditions
- Powers managed systems on and off
- Acts as a service focal point for service representatives to determine an appropriate service strategy and enable the Service Agent Call-Home capability
- Activates additional resources on demand
There is no serial RS-232 connection between the CWS and the HMC controlled servers or between the HMC and the CWS. Only the HMC has a serial connection to the HMC ports of the servers. For M/T 7039, additional RS-422 connections are needed between the Bulk Power Controllers (BPC) and the HMC. Because the HMC has only two integrated RS-232 ports, additional multiport adapters must be installed for these connections. An 8-port adapter can be used. This adapter supports both RS-232 and RS-422 connections.
