Verify the following prerequisites needed to setup Distributed Storage as a backup target in Commvault software.
Hedvig software version 4.2.1 (or later).
Hedvig software is supported on CentOS 7.x and RHEL 7.x.
Install the minimal version (7.7, as of this Hedvig release) of the CentOS on the storage nodes.
RHEL requires a valid subscription to RHEL server repositories.
An esx/hyperv/kvm for importing the OVA file to create the deployment VM.
An Ansible Configuration File. There are sample Ansible files in /opt/hedvig/samples on the Hedvig Deployment Server (after extracting hedvig_extract.bin).
Contact Commvault to get an Ansible Configuration File customized for your environment.
Commvault V11 with Service Pack 18 and Hot Fix Pack 5 (or a more recent version).
Root password is required to deploy both the Hedvig Storage nodes and the Hedvig Proxies.
All the storage nodes and the MediaAgents / Proxies must have static IP addresses, and the mapping from IP to hostname be updated in /etc/hosts even if DNS resolution is available.
Storage proxies are configured with 2 ethernet interfaces and run as an HA pair (except for storage proxies that are used for object storage). For failover to work correctly, a public VIP address and a private VIP address are required for the ethernet interfaces.
