Disks' Replication Policy
replication policy
DPOD has 3 disks (DPOD Developer Edition is not supported for HA\DR):
- Disk 1 – Operating System,
- Disk 2 – Application & Configuration,
- Disk 3 – Data of all monitored Data Power’s transaction and configuration.
- For launching DPOD server in a replicated environment customer must replicate Disk1 and Disk 2 on a regular basis as they usually have a reasonable rate of changes.
- Replicating Data Disk (Disk 3) can generate massive IOPS and bandwidth usage which can be a burden on the customer replication mechanism.
In cases it is acceptable for customer to launch its passive server without the data, customer can follow this step to create a clean working data disk (disk 3):- Customer must create a full back of disk 3 when all DPOD services are down.
- Customer must copy the backup of disk 3 to passive DPOD server storage and make sure it is attached to the passive DPOD server.
- Customer must start the passive DPOD server and verify that DPOD is fully started and operational.
- Customer should delete DPOD data (if exists) using the DPOD web console (Manage -> Internal Health -> Store)
- Customer can shut down the secondary DPOD and start the replication for DISK 1 and 2 only.
- After each DPOD upgrade it is recommended to rerun this procedure in case directory structure in Disk 3 changed.
