Now create a swap space on the RAID 0.
# mkswap –L SWAP /dev/sdb
Turn on swap.
# swapon –p 10 /dev/sdb
Edit /etc/fstab and add an entry for this swap device.
"LABEL=SWAP swap swap pri=10 0 0"
Make sure the entry is listed before the default swap space the OS install created.
Test that swap can be enabled automatically when the server boots.
# swapoff –a
# swapon -s
# swapon –a
# swapon –s
5. Configure an ib0 IP-address on the InfiniBand interface. This is the IP the I/O clients will use to
mount the NFS share. It should be on the same subnet as the I/O clients.
Reboot the server for all these changes to take effect.
A.4. Virtual disk configuration
Create a virtual disk on the PowerVault MD1200s. This disk will be used as the NFS storage. All the
commands in this section are executed on the PowerEdge R720 NFS server.
