Figure 2 Auto- discovery of host resources. On the next page (Figure 2), you will see the wizard attempt to auto- detect the resources on your target machines. If this fails (e. SSH server on the target hosts) then you can enter the data manually. You can also overwrite the resource- values – for example, if you don’t want the cluster to use up a big share of the memory on the target systems then just overwrite the amount of memory. It’s also on this page that you can specify where the My.
SQL Cluster software is stored on each of the hosts (if the defaults aren’t correct) – this should be the path to where you extracted the My. SQL Cluster tar- ball file – as well as where the data (and configuration files) should be stored.
