NFS server set up 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.

NFS server set up
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.
