What is HP SIM HP Systems Insight Manager (HP SIM) is an industry standard management tool for the management of all HP Systems; Servers and Storage. With HP SIM, you can manage various systems including ProLiant servers running Windows, Linux, and NetWare, HP Integrity and HP 9000 servers running HP-UX; HP Integrity Servers running Windows and Linux; and monitor Alpha servers running Tru64 UNIX and OpenVMS.
The two important pieces in HP SIM are the software and the database it maintains. On a Linux CMS, it can use either a PostgreSQL or an Oracle database. The HP SIM package consists of the following elements. HP SIM-Linux - HP Systems Insight Manager (C.05.00.02.00) Automatic BIN file installation kit which will provide: • hpsim-pgsql-config - HP Systems Insight Manager Repository Configuration Product (C.05.00.02.00) • postgresql RPM - Client programs and libraries (7.4.
Each system of the cluster is running RHEL 4 Update 4. Installing the HP SIM binary on system1 and system2 Install HP SIM on each node in parallel. Download the binary distribution under /tmp, and then execute the following steps. Run the regular installation steps as described on the HP SIM website. 1. To install HP SIM with PostgreSQL, execute the following command: # cd /tmp # ./HPSIM-Linux*.bin 2. The HPSIM-Linux*.
6. If they are not running, start them by executing the following command: # /opt/mx/bin/mxstart 7. After installing the HP SIM package perform the following steps to create the relevant directories on the shared storage, copy the contents of the original directory and create symbolic links. (respectively /etc/pam.d/mxpamauthrealm, /etc/opt/mx, / opt/mx, /var/opt/mx, /etc/init.d/hpsim, /var/lib/pgsql). 8. Stop the running processes first to avoid problems: # /etc/init.d/hpsim stop # /etc/init.

Create the HP SIM package by launching HP Serviceguard Manager and connect to the cluster to create the HP SIM package: Figure 2 • In the Package name field, enter HPSIM.
Figure 3 • Select Package autorun. • Select Configured system for Failover Policy. • Keep the default time out settings. Figure 4 • Add the 192.168.2.x and 10.0.0.x subnets to the Subnets monitored for the package field. • Enter thee IP address of the cluster, 192.1682.15 in our case, to the Specify addresses on subnet field and click Add(w) to add the IP address to the Configured IP Addresses box.
Figure 5 • Select Parallel for Concurrent vgchange operation. • Select Standard LVM activation for the Activation Method. • Enter the cluster aware volume groups, vgsg in our example, in the Cluster aware volume groups field and click Add to add it to the Package volume groups box. Figure 6 • Select Parallel for File system checking and enter1 in the Concurrent FSCK operations box. • Select Parallel for Mount operations and enter 1 in the Concurrent and unmount operations box.
• Click Add to add the FS Type (ext3), Volume Name (/dev/vgsg/lvsg), and the Mount Directory (/hpsimlnx). Figure 7 • In the Run command field, enter the path for the start script: /etc/init.d/sgsim start • In the Halt command field, enter the path for the stop script: /etc/init.d/sgsim stop # cat /etc/init.

Troubleshooting Finetuning of the HP SIM server • SELinux issue: If activated, postgreSQL does not start in the cluster script. You must apply the following patch: # # diff postgresql.
• Toolkit.sh modification: the script is not provided through HP Serviceguard Manager, for this paper the script from the MySQL toolkit was used and the following changes were applied: # diff HPSIM/toolkit.sh ../mysqltoolkit/toolkit.sh 43c43 < HA_SCRIPT="$PKG_DIR/HPSIM.sdf.sh" --> HA_SCRIPT="$PKG_DIR/hamysql.sh" 63c63 < Server." echo "$(date '+%b %e %T') - ERROR: Failed to $ACT SGSIM --> Server." echo "$(date '+%b %e %T') - ERROR: Failed to $ACT MySQL 107c107 < # . $HA_SCRIPT $ACT --> .
