Abstract This document describes the steps needed to install and integrate HP Data Protector Cluster Cell Manager on the Red Hat Cluster Suite (RHCS). Introduction This document describes the installation and integration of Cluster-aware Cell Manager on a Linux Cluster. The Red Hat Cluster Suite (RHCS) is considered as an example.

Configuring the shared DISK and GFS volume 1. To set up the gfs/gfs2 volume, start all the gfs/gfs2 services on each machine. Before this, ensure that GFS/GFS2 and RHCS components are installed on them. If not, install the components: GFS components: gfs-util, k-mod-gfs, Distributed Lock Manager (DLM) RHCS components: OpenAIS, CCS, fenced, CMAN and CLVMD (Clustered LVM) $yum install gfs-util kmod-gfs or $yum install gfs2-util 2.

In general, the procedure will work with later versions of Data Protector as well. 1.

Run the xomni command to check the DP GUI can be opened without any issue on the current node: $/opt/omni/bin/xomni & 4. Stop the Data Protector services on the secondary node, unmount the shared disk on it, and mount it on the primary node by repeating the above step on the primary node. Note: Create cluster resources using the cluster configuration tool (see the next section). $system-config-cluster 5. Import the virtual server client on to the Cell Manager. $/opt/omni/bin/omnicc -import_host dpi00180.

Figure 2: Creating a cluster disk resource group using the cluster configuration tool b. Create the resource Group IP, assign an IP address, and subnet. Check the Monitor Link option, and then click OK. Figure 3: Creating the Cluster IP resource group c. Create the Data Protector service group with file path /opt/omni/sbin/omnisv, and click OK.

Figure 4: Creating the DP Cell Manager Resource Group using the cluster configuration tool d. Create the Data Protector cluster service “dps”, and enable options as shown in Figure 5. That is, select Restart, select the Failover Domain of which primary and secondary nodes are members, and check Auto start This Service. Ensure that the shared disk and the Data Protector script are the dependent resources of the Virtual IP.

Figure 5: Creating the Data Protector Cell Manager Service using the cluster configuration tool Note: Add both resources groups (the shared Disk Group and the shared Data Protector Service Group) as dependencies to the IP Resource Group. Checking the order of appearance of Data Protector resources The order of the resources while starting the services should be as follows: a. Virtual IP b. Mount shared disk c.
