IBM TotalStorage Peer-to-Peer Virtual Tape Server Failover Test Scenarios in a zOS Environment

Tags:
mainframes

Overview The IBM TotalStorage Peer-to-Peer (PtP) Virtual Tape Server is designed so that no single component failure will result in loss of access to data. In addition, data access is also preserved during many multiple component failure situations. The complexity of the PtP VTS configuration, coupled with the large number of possible failure scenarios, has made the task of developing failover test plans a challenging one. This paper was written in an effort to assist IBM Specialists and customers in developing such plans. The paper documents a series of PtP VTS failover testing scenarios for zOS which were run in an IBM laboratory environment. Single failures of all major components and communication links and some multiple failures are simulated.

BlackBerry blackout: Is RIM overreaching itself?

Some of the most common issues that can result in an outage are power failures, failure of a critical component that takes down a larger component, software bugs, viruses and other attacks from the outside, or patches that fail.
