Discovering software on shared disks (BigFix scenario)

To discover software that is installed on shared disks, identify disks that exist in your infrastructure. Then, choose the method of scanning these disks that best suits your environment.

Software that is discovered on shared disks is reported on every computer on which the shared disk is mounted. It causes that license metric utilization that is calculated for the discovered software increases. When the software is reported on every computer on which the shared disk is mounted, it continues contributing to license metric utilization for the entire reporting period even if the shared disk is unmounted.

Requirements

  • Discovery of shared disks is supported on Linux, AIX, and Solaris. It is not supported on Windows and IBM i.
  • Types of discovered shared disks include UNIX Network File System (NFS) and Windows Common Internet File System (CIFS).
  • Types of software scan that are run on shared disks include catalog-based scan, and software identification tags scan.
  • If you have systems with multiple interfaces, ensure that you configure them correctly. For more information, see: Configuring servers in separate networks (BigFix scenario).

Optimized mode

Optimized mode is advised for environments with a heavy use of shared disks in which a single shared disk is mounted on many computers.
The image shows multiple shared disks that are mounted on multiple computers.
There are two methods of scanning in this mode: automatic and manual. Automatic mode is recommended as it is easier to set up and maintain. However, this mode scans all shared disks that exist in your environment. If you want to scan only selected shared disks, use manual scanning.
Important: Do not use automatic and manual scanning of shared disks at the same time.
9.2.12 Automatic scanning
In this method, one of the computers on which a shared disk is mounted is automatically designated to scan the disk and discover the installed software. The data is then populated to all computers on which the same shared disk is mounted. Every disk is scanned starting from the top level through all the child-level directories. In case only a child-level directory is mounted on a computer, this directory is not scanned again. The data is populated based on the scan of the top-level directory. For detailed instructions, see: Step 2a: Optimized mode - Automatic scanning of remote shared disks (BigFix scenario).
9.2.8 Manual scanning
The outcome of this method is the same as of automatic scanning. However, it requires more manual setup. In this method, you create computer groups that contain only computers on which the same disk is mounted. Then, you scan one of the computers in that group to create a software template. Finally, you share the template between all computers on which the disk is mounted.

The choice of the scanned computer depends on whether some of the computer groups are overlapping and whether computers that access the same shared disk run on various operating systems. For detailed instructions, see: Step 2b: Optimized mode - Manual scanning of remote shared disks (BigFix scenario).

Basic mode

Basic mode is advised for environments in which a single shared disk is mounted on one or only few computers. In this mode, every discovered shared disk is scanned by every computer on which the shared disk is mounted. If many computers scan the same shared disk, performance of the disk might decrease. For detailed instructions, see: Step 2c: Basic mode - Scanning remote shared disks (BigFix scenario).
