Hi,

We have a solaris cluster server with four servers. We already Veritas DMP installed on it and we want to install Powerpath on these server with one node at a time basis. These server are in  Production. Is there a Best Practise that we can follow of r the installation.

Following is the plan that we have.

We are planning to use Powerpath  for multipathing on all the unix servers , instead of DMP, our customer wants us to implement the Powerpath one node at a time in cluster , which means , suppose if we have 4 node cluster , we will be installing and using the Powerpath one node , which means , three nodes will be running DMP and one node will be running Powerpath , once it is success , they are ready to give us next server in the cluster for installing the powerpath.

The question is , we are interested (also best practice ) , installing the powerpath on all the nodes at a time instead of one by one.

are there any problem if we run some nodes in the cluster with  DMP and some with Powerpath.
