Running GPFS commands

Once GPFS™ is installed, the account you use for GPFS administrative operations (such as creating a cluster and file systems) will depend on your cluster type.

For Windows clusters, run GPFS commands as a member of the Domain Admins group or as a domain account that is part of the local Administrators group. For clusters with both Windows and UNIX nodes, run GPFS commands as root, a special domain user account described in Creating the GPFS administrative account.

You must run all GPFS commands from either a GPFS Admin Command Prompt or a GPFS Admin Korn Shell. The GPFS administrative commands may not work properly if issued from the Cygwin Terminal. Open a new GPFS Admin Command Prompt or GPFS Admin Korn Shell after installing GPFS so that it uses the updated PATH environment variable required to execute GPFS commands.

GPFS Admin Command Prompt and GPFS Admin Korn Shell can be accessed using their desktop shortcuts or from under the IBM GPFS Start menu group. Each of these program links starts its respective shell using the Run as Administrator option.
