About this course

Course code TPH6285S
Duration 4 Days

This course covers the procedures necessary for setting up and managing the HP-UX disk subsystem using Logical Volume Manager (LVM). You will also gain experience with MirrorDisk/UX using various recovery techniques to provide data redundancy and protection against possible disk failure. The course is 50 percent lecture and 50 percent hands-on labs using HP servers.
