Problems with running commands on other nodes

This topic describes the problems that you might encounter relating to running remote commands during installing and configuring IBM Storage Scale.

Many of the GPFS administration commands perform operations on nodes other than the node on which the command was issued. This is achieved by utilizing a remote invocation shell and a remote file copy command. By default, these items are /usr/bin/ssh and /usr/bin/scp. You also have the option of specifying your own remote shell and remote file copy commands to be used instead of the default ssh and scp. The remote shell and copy commands must adhere to the same syntax forms as ssh and scp but may implement an alternate authentication mechanism. For more information on the mmcrcluster and mmchcluster commands, see mmcrcluster command and mmchcluster command. These are problems you may encounter with the use of remote commands.
