Adding the SSH hostprovider
To manage a cluster and its nodes via ADCM, it is necessary to prepare hosts for a cluster and link these hosts to ADCM. This is the function of ADCM hostproviders — special plugins for ADCM, that encapsulate the complex mechanism of interaction between ADCM and the hosts controlled by it.
There are several types of hostproviders in ADCM. This topic shows how to add the simplest SSH hostprovider, that allows to connect to the existing hosts using the SSH protocol. During offline installation this is the most suitable hostprovider type.
A typical installation sequence for the SSH hostprovider includes the following steps.
