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 prior to proceeding to the next step.
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 re-directed 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.
