SARES1
This 3390-3 volume contains a single volume stand alone system. This volume can be used to IPL and logon to a TSO/ISPF session.
The disk volume can assist in building LPAR environments and correct errors that prevent system IPL.
Recommended use of this volume is to install the volume and leave accessible. The volume should not be altered. The volume should stay in a background mode and be available for emergency type of situations. If other z/OS, OS/390, or LPAR partitions contain errors, the SARES1 volume could be used to solve the problem.
The stand alone system does not contain TCPIP or Unix system service support. The system cannot be used to install products or apply maintenance via SMP/E.
