Prerequisites for Monitoring Unix Servers using OpStor

OpStor provides monitoring and management of Unix servers in a SAN environment.

Models Supported

• Unix servers like Linux, Solaris, HP UX & IBM AIX

Features Supported

OpStor provides information of the following components on the Host Servers,

Storage resources

• SCSI / Fibre-channel Host Bus Adapter details
• Remote end storage device details

System Resources

• CPU usage
• Memory usage
• Disk usage & I/O statistics
• Ethernet link status
• Inventory details of server components such as Processor, Ethernet card, CDROM drive, etc.

Prerequisites for Monitoring

• Starting the host server platform SNMP service
  • Start the platform SNMP service if not already started.
    
    • Proceedure to install & start SNMP service in HP-UX servers :

  • Download the relevant net-snmp package from the URL:  http://sourceforge.net/project/showfiles.php?group_id=12694  For example, if the HP-UX version is 11.11, download the file net-snmp-5.2.1-HP-UX_B11.11_9000_800.tar.gz
  • Install the tar as root under "/" directory in the HP-UX machine.
  • Run snmpconf present in /usr/local/bin directory to configure necessary SNMP parameters.
  • Now, start the SNMP daemon by executing snmpd present in /usr/local/sbin directory.

  • Proceedure to install & start SNMP service in Solaris servers:

    • Download the relevant net-snmp package from the URL:  http://sourceforge.net/project/showfiles.php?group_id=12694  For example, if the SUN OS version is UltraSparc 5.8, download the file net-snmp-5.1.2-SunOS_5.8_sun4u.tar.gz
    • Install the tar as root under "/" directory in the HP-UX machine.
    • Run snmpconf present in /usr/local/bin directory to configure necessary SNMP parameters.
    • Now, start the SNMP daemon by executing snmpd present in /usr/local/sbin directory.

     

  • OpStor uses "public" snmp comunity to talk to Host Servers. Check if the snmp community name "public" is configured with "read-only" privileges.If not then add that community.
    • If any modifications are made, then save them and restart the SNMP service. This is required for these changes to take effect.
  • A telnet account with username "guest" and password "guest" needs to be added (Recommended) . This will be mandatory in case SNMP service is not available.
    

• HBA Discovery: If HBAs are present in the host server , ensure that the HBA Agent is installed and running . Download URL & installation instructions for each OS is available at ,
  HBA Agent Download & Installation

• Start OpStor if it is not running already
• Connect to OpStor webclient
• Navigate to 'Admin tab' --> 'Manage Storage Devices' link in OpStor Webclient
• Specify the IP of the host server[If the host is already discovered before HBA agent is started / devcon is installed , please delete the host server before adding it as explained here]
• If the read community is other than "public" , choose 'SNMP' option and specify it in the "community" field
  
• Click "Add Device"
