Chapter 1. Introduction to Red Hat Storage for Virtualization
- Red Hat Enterprise Virtualization environment.See Red Hat Enterprise Virtualization Architecture in Introduction in Red Hat Enterprise Virtualization Installation Guide.
- Red Hat Storage environment.A Red Hat Storage environment consists of bricks that are used to build volumes. Different types of optimized storage volumes can be used as virtual machine stores to hold resources such as virtual disks, templates, and snapshots.

- Update Red Hat StorageEnsure that your system is up to date with the latest patches and upgrades. Use the following command to install the software updates:
# yum update
ImportantSee the upgrade steps mentioned in the Red Hat Storage Installation Guide to upgrade to the latest version.
- Download the
.isofile for the latest version of Red Hat StorageDownload the
.isofile that holds the installation sources before you start the installation on the system.Verify the MD5 checksums for the
.isofile to ensure that the download is successful.If you have a subscription or evaluation subscription, follow the steps to obtain the Red Hat Storage

- Verify the system requirements.The system must satisfy the requirements to ensure smooth integration of Red Hat Enterprise Virtualization and Red Hat Storage. See System Requirements in the Red Hat Enterprise Virtualization Installation Guide, which outlines the minimum system requirements required to install, configure, and operate a Red Hat Enterprise Virtualization environment. Also, see the hardware compatibility matrix and system requirements outlined in the section Planning Red Hat Storage Installation of the Red Hat Storage Installation Guide.When creating a data center in Red Hat Enterprise Virtualization Manager, ensure that you select the compatibility version as 3.4. See the compatibility matrix for information on backward compatibility of earlier versions.
- Subscribe to the Red Hat Enterprise Virtualization channels.Subscribe to the Red Hat Enterprise Virt Management Agent channel on all Red Hat Enterprise Linux 6.3, 6.4, and 6.5 hypervisors that now act as the clients for your Red Hat Storage volumes.
- Subscribe to the Red Hat Storage Native Client channel.Subscribe to all Red Hat Enterprise Linux 6.3, 6.4, and 6.5 hypervisors to the Red Hat Storage Native Client channel to get the latest version.
- Set the fully qualified domain name for each hypervisor.Correct DNS records must exist for each hypervisor and Red Hat Storage server node. A fully qualified domain name must be resolvable via both forward and reverse DNS lookup.
- Set SELinux booleans.If you are using QEMU/KVM as a hypervisor, ensure that you set the following SELinux booleans:
# setsebool -P sanlock_use_fusefs on # setsebool -P virt_use_sanlock on # setsebool -P virt_use_fusefs on
