The implementation of IBM Server HACMP has always been the importance of IBM. The following is a detailed installation and configuration process, which is very helpful for learning HACMP: Environment: Two p630: P630_1, P630_2 Disk display: 7133-D40 sharing volume group: oravg1 On the two computers (1) on the P630_1 machine: a.
