Add disk space to a SIEM device running on a virtual machine.

  • Back up your data. Script failure could cause data loss.

  • The disk must have a partition mounted on one of:

    • /

    • /db1

    • /db2

    • /ss1

  • Make sure the mounted partition is the last partition on the disk.

Caution

This procedure entails risk. Script failure could cause data loss, requiring you to restore data from a backup.

Minimum disk space requirements:

  • System storage - 500 GB

  • Data storage - 500 GB

  • Index drive - 250-GB high-performance SSD

  1. Contact Trellix Support to assist with this operation.

  2. Use the VM hypervisor to enlarge the disk so that there is at least 10 GB of unallocated space.

  3. Run the resizing script (ResizeVmVolume).

    The script:

    • Stops cpservice and all databases

    • Re-creates the last partition using all unallocated space

    • Resizes the file system

    • Updates the drivesetup.conf configuration file

    • Changes the size of each database

    • Restarts services
