HP-UX Logical Volume Manager (LVM)

( Duration: 4 Days )

In HP-UX Logical Volume Manager (LVM) training course, you will learn 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.

By attending HP-UX Logical Volume Manager (LVM) workshop, delegates will learn to:

  • 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

  • Experience with HP-UX System and Network Administration

  • This HP-UX Logical Volume Manager (LVM) class is targeted at Experienced HP-UX system administrators
