After a policy is configured and run successfully, a failover may be initiated with the following steps:
To stop services on the source cluster, run the following commands:
Source-cluster# isi services smb disable
Source-cluster# isi services nfs disable
Source-cluster# isi services vsftpd disable
Source-cluster# isi sync policies modify [Policy Name] –schedule “”
Source-cluster# isi sync jobs start [Policy Name]
Ensure that the policy completes before proceeding to the next step.
To perform this work from the CLI, run the following command:
Target-cluster# isi sync recovery allow-write –-policy-name=[Policy Name]
At this point, the target cluster is now accessible and writable.
Clients must now be redirected to the target cluster to continue accessing the file system. Make any necessary network, DNS, and environmental updates. Depending on the DNS configuration, a single DNS update only changing the forwarding is sufficient.
