Duration: 4 Days
In this course, you will cover the procedures necessary for setting up and managing the HP-UX disk subsystem using Logical Volume Manager (LVM). You will gain experience with MirrorDisk/UX using various recovery techniques to provide data redundancy and protection against possible disk failure. You will spend 50 percent of class using HP servers in hands-on labs.
What You Will Learn
- Configure and manage LVM disks, disk groups, and logical volumes
- Configure striped, mirrored, and distributed logical volumes
- Configure LVM for optimal performance
- Recover failed LVM disks and volumes
- Mirror LVM data and boot disks to improve uptime and reliability
- Replace failed LVM data and boot disks
