Prerequisites for Monitoring

Starting the host server platform SNMP service
- Start the platform SNMP service if not already started.
- Check the SNMP service Security settings. This can be viewed via Start -> Settings -> Control Panel -> Administartive Tools -> Services -> SNMP Service -> (Right-click) Properties -> Security (tab)
  - OpStor uses "public" snmp comunity to talk to Host Servers. Check if the snmp community name "public" is available in the text-window under "Accepted Comunity Names" with "READ-ONLY" rights.If not then add that community.
  - Check if the server running OpStor is allowed to access this SNMP Service. To do this, check if the IP of the server running OpStor is available in the "Accept SNMP packets from these hosts" text-window. If not, then add that IP address.
  - If any modifications are made, then save them by selecting "Apply" and restart the SNMP service. This is required for these changes to take effect.

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

SCSI Discovery: In addition, if it is required to get the list of SCSI adapters & attached SCSI devices in the server (applicable for Windows 2000 based servers) , the MicoSoft utility devcon.exe needs to be installed in the server where OpStor is running.

Go to the server where OpStor is installed.
Download devcon.exe from Microsoft site.
Run <devcon_download_dir> devon.exe
- This opens up a dialog box asking to 'UnZip'
- Select 'UnZip' option and choose a directory <devcon_install_dir>
- This will create two dirs namely <devcon_install_dir>/I386 and <devcon_install_dir>/Ia64
- If your Windows machine is 32-bit Processor based, keep <devcon_install_dir>/ I386 to PATH [set the PATH environment variable]
- If your Windows machine is 64-bit Processor based, keep <devcon_install_dir>/ Ia64 to PATH [set the PATH environment variable]
Delete <devcon_download_dir>/devcon.exe [This exe is not required and should not be in the PATH]
Restart OpStor (This is required for devcon to be included in the PATH for OpStor)
devon.exe detailed documentation is available online for reference

Steps to add the device for monitoring in the OpStor Browser client

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"
