Examples of consolidating NFS export rules and Snapshot schedules for transition

You might want to review examples of how similar 7-Mode export rules and 7-Mode Snapshot schedules are consolidated to a single NFS export policy and a single Snapshot policy in ONTAP. You might also want to understand how the consolidated policies are assigned to the transitioned volumes or qtrees with or without reusing a matching existing policy on the target SVM.
Example of consolidating NFS export rules for transition
NFS export rules in 7-Mode and ONTAP before transition
7-Mode export rules
/vol/vol1 -sec=sys,rw,nosuid /vol/vol2 -sec=sys,rw,nosuid /vol/vol3 -sec=sys,rw,nosuid
Export policies existing in ONTAP
cluster-2::> vserver export-policy show -vserver vs1 Vserver Policy Name --------------- ------------------- vs1 default vs1 export_policy_1
The existing export policy export_policy_1 has the following export rule:
cluster-2::> vserver export-policy rule show -vserver vs1 -policyname export_policy_1
Policy Rule Access Client RO
Vserver Name Index Protocol Match Rule
------------ --------------- ------ -------- --------------------- ---------
vs1 export_policy_1 1 nfs 0.0.0.0/0 sys
Export policies in ONTAP after transition with consolidation (no reuse)
Volumes vol1, vol2, and vol3 have similar export rules in 7-Mode; therefore, a new consolidated export policy, transition_export_policy_1, is assigned to these volumes after transition:
cluster-2::> vserver export-policy show -vserver vs1 Vserver Policy Name --------------- ------------------- vs1 default vs1 export_policy_1 vs1 transition_export_policy_1 3 entries were displayed.
cluster-2::> vserver export-policy rule show -vserver vs1 -policyname transition_export_policy_1
Policy Rule Access Client RO
Vserver Name Index Protocol Match Rule
------------ --------------- ------ -------- --------------------- ---------
vs1 transition_export_policy_1
1 nfs 0.0.0.0/0 sys
cluster-2::> volume show -vserver vs1 -volume vol1,vol2,vol3 -fields policy vserver volume policy ------- ------ -------------------------- vs1 vol1 transition_export_policy_1 vs1 vol2 transition_export_policy_1 vs1 vol3 transition_export_policy_1 3 entries were displayed.
Export policies in ONTAP after transition with consolidation and reuse
Volumes vol1, vol2, and vol3 have similar export rules in 7-Mode; therefore, a consolidated export policy is assigned to these volumes after transition. The export policy, export_policy_1, which matches the 7-Mode export rules, already exists on the SVM. Therefore, the policy is applied to these volumes:
cluster-2::> vserver export-policy show -vserver vs1 Vserver Policy Name --------------- ------------------- vs1 default vs1 export_policy_1 2 entries were displayed.
cluster-2::> vserver export-policy rule show -vserver vs1 -policyname export_policy_1
Policy Rule Access Client RO
Vserver Name Index Protocol Match Rule
------------ --------------- ------ -------- --------------------- ---------
vs1 export_policy_1 1 nfs 0.0.0.0/0 sys
cluster-2::> volume show -vserver vs1 -volume vol1,vol2,vol3 -fields policy vserver volume policy ------- ------ -------------------------- vs1 vol1 export_policy_1 vs1 vol2 export_policy_1 vs1 vol3 export_policy_1 3 entries were displayed.
