VxVM cheatsheet

Veritas Volume Manager (VxVM) enables us to manage physical drives as logical devices. Applications and the operating system see a veritas disk/volume as a physical disc with configurable file systems, databases, and other managed data objects.

For computer and Storage Area Network (SAN) systems, VxVM offers simple online disc storage management. In order to boost I/O throughput and safeguard against hardware failure, VxVM can be configured to support the Redundant Array of Independent Disks (RAID) concept. Moreover, VxVM has capabilities that improve disc failure quick recovery and fault tolerance.

By offering a logical volume management layer, VxVM gets around the physical limitations imposed by hardware disc devices. Volumes can now span several discs thanks to this.

VxVM offers the resources needed to boost efficiency and guarantee the availability and integrity of data. While the system is running, you can utilise VxVM to dynamically configure disc storage.

Create Volume with RAID-1+0:

# vxassist -g <diskgroup> make <volname> layout=raid10 <subdisk1> <subdisk2> <subdisk3> <subdisk4>

Example:

vxassist -g mydg make myvol layout=raid10 mysubdisk1 mysubdisk2 mysubdisk3 mydisk5>

Example:

vxassist -g mydg make myvol layout=raid60 mysubdisk1 mysubdisk2 mysubdisk3 mysubdisk4 mysubdisk5 mysubdisk6
