During installation, DEFAULT and SYSTEM accounts are created automatically. You should create additional user accounts now. If you plan to have HP service representatives test your system or if you plan to run testing software such as UETP, you must create accounts for each representative and a SYSTEST (standalone system) or SYSTEST_CLIG (OpenVMS Cluster system) account to run UETP.
For complete information about creating and managing user accounts and about creating accounts for HP service representatives and UETP, see the HP OpenVMS System Manager's Manual, Volume 1: Essentials.
