Dell HPC NFS Storage Solution - High Availability Configurations
Page 34
A.3. Initial software configuration on each PowerEdge R710
1) Install the RHEL5.5 x86_64 operating system on the RAID1 virtual disk.
 Make sure MD storage is not attached to the servers during the OS install.
2) After the OS is installed, setup swap on the RAID0 device.
 multipath –ll will show the device associated with the PERC H700, such as
/dev/mapper/mpath1
 # mkswap -L SWAP /dev/mapper/mpath1
 # swapon –p 10 /dev/mapper/mpath1
 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, if any.
 Test that swap can be enabled automatically when the server boots
# swapoff –a
# swapon -s
# swapon –a
# swapon –s
3) Copy the RHEL 5.5 DVD to the server and create yum repositories. On each server:
 # cp –r /media/RHEL5.5 /root/
# rpm -ivh /root/RHEL5.5/Server/createrepo-0.4.11-3.el5.noarch.rpm
# cd /root/RHEL5.5/Server; createrepo .
# cd /root/RHEL5.5/VT; createrepo .
# cd /root/RHEL5.5/Cluster; createrepo .
# cd /root/RHEL5.5/ClusterStorage; createrepo .
 Create files similar to the example below for each repository.
/etc/yum.repos.d/Server.repo
/etc/yum.repos.d/Cluster.repo
/etc/yum.repos.d/ClusterStorage.repo
/etc/yum.repos.d/VT.repo
Example .repo file:
[root@active]# cat /etc/yum.repos.d/Server.repo
[Server]
name=Server
baseurl=file:///root/RHEL5.5/Server
enabled=1
gpgcheck=0
 Check the repositories.
[root@passive]# yum repolist
