You can restore an SAP HANA database after a primary storage system running clustered Data ONTAP fails.
Before you begin
Assuming the primary volume is lost completely, you need to create a new primary volume and then restore from the backup volume.
Steps
- Create a primary volume with type data protection.
Example
hana::> volume create -vserver hana1a -volume hana_data -aggregate aggr_sas_101 -size 300G -state online -type DP -policy default -autosize-mode grow_shrink -space-guarantee none
-snapshot-policy none -foreground true
[Job 6744] Job is queued: Create hana_data.
[Job 6744] Job succeeded: Successful
- Restore all data from the backup volume.
Example
hana::> snapmirror restore -destination-path hana1a:hana_data -source-path hana2b:backup_hana_data -source-snapshot sc-backup-daily_20140505121000
[Job 6746] Job is queued: snapmirror restore from source "hana2b:backup_hana_data" for the
snapshot sc-backup-daily_20140505121000.
hana::> job show -id 6746
