Starting the EVM Server and EVM Clients

The EVM program and its associated support scripts are installed with root execute permission only. To run EVM, you must have root permissions.

After EVM is first installed on a computer, it is necessary to add EVM-related environment variables before starting. See Environment Variables

 

Manually Starting EVM

After you have configured the environment, perform the following steps to manually start EVM.


IMPORTANT:  In some cases EVM uses relative paths and may not work correctly if the EVM program is executed from anywhere other than $EVM_HOME/bin.


 

  1. Open a terminal window and change the present working directory to $EVM_HOME/bin.

  2. Enter evm. After being started, EVM detects and gathers information about the storage configuration and SAN topology  and then displays a Ready indicator. In most cases, EVM completes its startup tasks in two minutes or less.

 

Browsing to EVM

You access EVM by using a Web browser. See Browsing to the Device Home Page.

 

Keeping the EVM Server Process Running

The EVM Server must be running to create, run, monitor or manage EVM jobs. Do not end the EVM process unless you are intentionally shutting down the EVM Network.


CAUTION:


 

Keeping the EVM Client Process Running

The EVM Client must be running to allow the computer to participate in EVM jobs. Do not end the EVM Client process unless you are intentionally shutting down the EVM Client.


CAUTION: When you end the EVM Client process the computer cannot participate in EVM jobs.
