Installing PowerPath

5.You are prompted for the directory where the PowerPath program files will be installed:

Enter package base directory (default: /opt,?):

Press ENTER to accept the default base directory (/opt), or type the path to an alternate base directory and press ENTER.

PowerPath installs its files in /basedir/EMCpower; the installation process creates the EMCpower subdirectory. Make a note of the name and location of the PowerPath base directory for future reference.

6. You are prompted for the directory where the log files will reside:

Enter directory for logging (default: /basedir/EMCpower/log):

Press ENTER to accept the default (/basedir/EMCpower/log), or type the path to an alternate log files directory and press ENTER. You must specify a local file system.

7.You see the following prompt:

Install for cluster environment [y,n,q,?] (default: n):

•If you are installing PowerPath on a standalone system, press ENTER. Go to step 10.

•If you are installing PowerPath in a clustered environment, enter y and press ENTER. Continue with step 8.

8.You are prompted for a major number that can be assigned to the PowerPath device driver (emcp) on every host in the cluster:

Assign major number for the device driver [?]:

Enter a major number and press ENTER. You must specify a major number that is not used by any host in the cluster.

The installation will assign this major number to the PowerPath driver. Specify this major number during PowerPath installation on every other host in the cluster.
