This document is Volume 3 of the VAXcluster Maintenance student workbook. It covers essential topics for maintaining a VAXcluster environment, including:

• VAXcluster Types: Overview of homogeneous, heterogeneous, and mixed configurations, along with the quorum scheme for preventing cluster partitioning.
• System Booting: Procedures for booting systems in a VAXcluster using a CI port, including booting from local versus HSC-based disks.
• Device Naming: Naming conventions for devices in a cluster, including dual-ported device naming, allocation classes, and volume shadowing.
• System Directory Structure: Explanations of system roots, common vs. node-specific directories, and the use of logical names for search lists.
• VMS Build in a Cluster: Guidelines for building VMS on a common system disk, including the use of AUTOGEN and managing SYSGEN parameters.
• Maintenance Tools: Descriptions of diagnostic and monitoring tools such as VAXsim, the ANALYZE/ERROR_LOG utility, the Monitor Cluster Utility, the Show Cluster Utility, and the role of DECnet in troubleshooting.
