Preinstallation Requirements

See also. For the latest system compatibility details regarding supported hardware, file systems, applications, operating systems, and service packs, see the Compatibility Guide.

Note the following additional preinstallation requirements:

• Linux LVM2 Requirement. LVM2 is required on all DPX Linux clients' file systems including root.

  Each VG Group must set aside at least 10% unallocated space, reserved as unused empty space. If the VG space is already completely allocated, more space needs to be added.

• Linux Change Journal Requirement. Change Journal installation requires that the following components are on any DPX Linux client: make, compiler, kernel-devel package. Note that RHEL 6.7, CentOS 6.7, RHEL 7.x, CentOS 7.x, SLES 11 SP4, and SLES 12.x and later do not use the change journal driver; therefore the Linux change Journal Requirements are not required for those Linux flavors.

• VMware Tools Requirement. Installation on a virtual machine requires VMware Tools on the virtual machine.

Note. In addition to DPX Block Data Protection agents, DPX also can manage NetApp OSSV agents. Customers must have NetApp OSSV agents in their environment already or they must order them from their DPX distributor. Procedures for installation and testing of NetApp OSSV agents are not included in this topic.
