Run: `# yum install nfs-utils nfs-utils-lib`\n- Make sure rpcbind /portmapper package is installed on the Linux host. Run:`# rpm -qa | grep rpcbind`\n\nThis should return something like: `rpcbind-0.2.0-11.el6.x86_64`\n\n- If you see nothing, then use yum to install the rpcbind. Run: `# yum install rpcbind`\n\nInstall the NFS client on a SLES Linux host\n-------------------------------------------\n\n1. To see if the client is installed, run: `# rpm -qa | grep nfs`\n\n This should return something similar to: \n\n nfs-client-1.2.1-2.6.6\n yast2-nfs-common-2.17.7-1.1.2\n yast2-nfs-client-2.17.12-0.1.81\n\n2. If you don't see either nfs-client or yast2-nfs-xxxx packages, then use\n either YaST or zypper to install the NFS client packages.\n\n - Using YaST:\n\n # yast2 --install yast2-nfs-client\n # yast2 --install yast2-nfs-common\n\n - Using Zypper:`# zypper install nfs-client`\n3. Make sure rpcbind or portmapper package is installed on the Linux host. Run:\n `# rpm -qa | grep rpcbind`\n This should return something like: rpcbind-0.1.6+git20080930-6.15\n\n4. If you see nothing, then you must install the packages using either YaST or\n zypper:\n\n - Using YaST: `# yast2 --install rpcbind`\n - Using Zypper: `# zypper install rpcbind`\n\nLearn NFS client information from the Linux host\n------------------------------------------------\n\nA Backup and DR-approved NFS client package and version must be installed on\nthe host.\n\n1. Check if the portmapper or rpcbind service is running. Run:\n `# sudo service rpcbind status`\n\n - A Red Hat RHEL 6 or CentOS Linux host should return something like: `rpcbind (pid 1591) is running...`\n - An SLES Linux host should return something like: `Checking for service rpcbind running`\n2. If rpcbind service is not running on Linux host, start it with:\n `# sudo service rpcbind start`\n\n3. Use rpcinfo to list the registered RPC programs or services. Portmapper\n must be registered and running.\n\n # sudo rpcinfo -p\n program vers proto port service\n 100000 4 tcp 111 portmapper\n 100000 3 tcp 111 portmapper\n 100000 2 tcp 111 portmapper\n 100000 4 udp 111 portmapper\n 100000 3 udp 111 portmapper\n 100000 2 udp 111 portmapper\n\n4.
