Example: Replacing a storage server in a cascading, targeted Auto Image Replication configuration
This example walks through the steps necessary to replace an MSDP storage server in a cascading, targeted Auto Image Replication configuration. The changes to the replication and the storage lifecycle topologies are tracked throughout the example.
The environment contains three domains. Each domain contains one or more MDSP storage servers.
Table: Example configuration
Domains | Storage servers | Storage lifecycle policies |
|---|---|---|
D1 | D1_MSDP | BACKUP_D1 |
D2 | D2_MSDP D2_MSDP_2 | IMPORT_D2 |
D3 | D3_MSDP | IMPORT_D3 |
To replace the storage server D2_MSDP with D2_MSDP_2
- Add replication target relationship from D2_MSDP_2 to D3_MSDP.
- Refresh disk pools in both domain D2 and domain D3.
- Copy IMPORT_D2 and modify name to IMPORT_2_D2 and destination storage to a storage unit on D2_MSDP_2.
- Add a replication target relationship from D1_MSDP to D2_MSDP_2.
- Refresh disk pools in both domains.
- Modify BACKUP_D1 Replication Operation Target import SLP to IMPORT_2_D2.
- Remove the replication target relationship from D1_MSDP to D2_MSDP_1.
- Refresh the disk pools in both domains.
- Run the following command in D1:
nbdecommission - oldserver MSDP_D2 - machinetype replication_host
- Delete IMPORT_D2.
- Remove the replication target relationship from D2_MSDP_1 to D3_MSDP.
- Refresh disk pools in both domains.
