After the PowerEdge R720 server is ready and cabled to the PowerVault MD1200, check Table 2 and
Table 4 for details on the software used for the solution.
1. Create two virtual disks on the five internal disks of the PowerEdge R720. This can be done through
the Ctrl+R menu on server boot-up.
• One RAID 1 virtual disk on two drives. This will be used for the operating system. Configure
one additional drive as the hot spare for this RAID group.
One RAID 0 virtual disk on two drives. This will be used for swap space.
2. Install Red Hat Enterprise Linux (RHEL 6.3) on the RAID 1 virtual disk of the PowerEdge R720.
To use any GUI features of DFC or Dell OpenManage, select the “Desktop” group of
packages.
3. This solution is based on the 2.6.32-279.14.1.el6.x86_64 errata kernel for RHEL 6.3. Install this
errata kernel version including kernel-devel and kernel-firmware rpms. Add these kernel
rpms to the system using the “rpm -ivh” flags. Do not upgrade the kernel version (“Uvh”).
4. Reboot the server into the .14.1 kernel. Double check the kernel version.
