Setup data protection for an Infinite Volume
Goal
This
workflow sets up a data protection mirror relationship for an Infinite Volume.
This workflow will –
·
Associate
a specific snapshot policy with the Infinite Volume. Enables tape backup by
enabling the SnapDiff option. This creates a namespace mirror constituent on
every node of the cluster.
·
Setup
a SnapMirror relationship for the provided Infinite Volume and secondary (dp)
Infinite Volume by performing the following steps:
a. Create a peering
relationship between source and destination clusters using the existing
intercluster LIFs. If a cluster peer relationship is already established, this
step is skipped.
b.
Create a peering relationship between the source and destination Storage
Virtual Machines.
c.
Establish a SnapMirror relationship between the primary and secondary Infinite
Volumes.
d.
Wait for SnapMirror initialization to complete.
Input
Parameters:
·
Primary
Cluster* [Mandatory]: The Clustered ONTAP storage system hosting primary
volume. Note that Infinite Volume feature is available from ONTAP 8.2.0 and
above, so only those applicable clusters will be shortlisted and shown in the
drop down list. This list would be a tabular resource selection showing Cluster
Name, Primary Address and ONTAP version.
·
Primary
Storage Virtual Machine *[Mandatory]: Storage Virtual
Machine hosting the primary Infinite Volume. The query will display a tabular
list having Storage Virtual Machine name, Infinite Volume name, Infinite Volume
Size (TB), Infinite Volume type (without storage class/with storage class) and
Tape backup Enabled (true/false). Query also ensures that only repository
Storage Virtual Machines of type “data” and only those Storage Virtual Machines
that contain volumes of style “infinivol”, state “online” and type “rw” are
selected.
·
Snapshot Policy * [Mandatory]: Snapshot
policy to be assigned to the primary volume. This policy determines the
schedules, retention counts, and naming for the local snapshots. If not
specified (value = NO CHANGE), the existing snapshot policy assigned to the
volume is left unchanged.
·
Enable tape backups: This is a Boolean input value and when
enabled, this option will create a namespace mirror constituent on every node
of the cluster where a data constituent resides, unchecked by default
·
Create SnapMirror relationship: This is a Boolean input value and
this option when enabled will create a SnapMirror relationship between primary
and secondary Infinite Volumes. Note this option is checked by default and if
unchecked, the entire SnapMirror Relationship Settings group is disabled.

Relationship Settings user input
·
Secondary Cluster *[Mandatory]: The Clustered ONTAP storage system
hosting destination Storage Virtual Machine and Infinite Volume of the
SnapMirror relationship. Note that Infinite Volume feature is available from
ONTAP 8.2.0 and above, so only those applicable clusters will be shortlisted
and shown in the drop down list. This list would be a tabular resource
selection showing Cluster Name, Primary Address and ONTAP version.
·
Secondary Storage Virtual Machine * [Mandatory]: Storage Virtual
Machine hosting the SnapMirror destination Infinite Volume. The query will
display a tabular list having Storage Virtual Machine name, Infinite Volume name
and Infinite Volume Size (TB). Query also ensures that only repository Storage
Virtual Machines of type “data” and only those Storage Virtual Machines that
contain volumes of style “infinivol”, state “online” and type “dp” are selected
·
Policy *[Mandatory]: The protection policy to be attached to the
new SnapMirror relationship. The query will result in a tabular list showing
Policy Name, Comment and Transfer Priority to the user for selection.
Transfer Schedule*[Mandatory]: Schedule for transferring snapshots to the SnapMirror destination. The
tabular list will show schedule and
description to the user for selection.
Result
These workflows will set-up a Data protection for an Infinite Volume. The
workflow would result in creating a SnapMirror relationship between source
Infinite Volume and “dp” Infinite Volume.
