Enable Password-less SSH
The installer will be able to password-less configure SSH/RSH among the cluster nodes, but it will not be able to enable this required functionality between the cluster nodes and the CP servers. For example, later setting changes, like modifying the IO fencing configuration, may need password-less SSH/RSH. In this configuration we are going to configure password-less SSH between the node that we will be using to configure the cluster and the rest of the nodes.
The following are the instances where Password-less SSH will be enabled:
Table: Instances to enable password-less SSH
Source | Target | Reason |
---|---|---|
cfs01 | cfs02 | Cluster configuration |
cfs01 | cfs03 | Cluster configuration |
cfs01 | cfs04 | Cluster configuration |
cfs01 | cps01 | Non-SCSI-3 fencing configuration |
cfs01 | cps2 | Non-SCSI-3 fencing configuration |
cfs01 | cps3 | Non-SCSI-3 fencing configuration |
cps01 | cps01 | Secure cluster configuration |
cps2 | cps01 | Secure cluster configuration |
cps3 | cps01 | Secure cluster configuration |
If you do not enable Password-less SSH, then follow the manual configuration instructions given at the end of this document.
