Creare un volume di destinazione

È necessario creare il volume di destinazione con il tipo DP per contrassegnarlo come destinazione di replica.

FsxId05f7f00af49dc7a3e::> volume create -vserver sapcc-backup-target-zone5  -volume PFX_data_mnt00001 -aggregate aggr1 -size 100GB -state online -policy default -type DP -autosize-mode grow_shrink -snapshot-policy none -foreground true -tiering-policy all -anti-ransomware-state disabled
[Job 42] Job succeeded: Successful

Creare un criterio SnapMirror

Il criterio SnapMirror e la regola aggiunta definiscono la conservazione e l'etichetta SnapMirror per identificare le istantanee da replicare. Quando si crea il criterio SnapCenter in un secondo momento, è necessario utilizzare la stessa etichetta.

FsxId05f7f00af49dc7a3e::> snapmirror policy create -policy snapcenter-policy -tries 8 -transfer-priority normal -ignore-atime false -restart always -type vault -vserver sapcc-backup-target-zone5

FsxId05f7f00af49dc7a3e::> snapmirror policy add-rule -vserver sapcc-backup-target-zone5  -policy snapcenter-policy -snapmirror-label snapcenter -keep 14

        snapcenter-policy  vault         1     8  normal  -
  SnapMirror Label: snapcenter                         Keep:      14
                                                 Total Keep:      14

Creare una relazione SnapMirror

Ora viene definita la relazione tra il volume di origine e quello di destinazione, oltre al tipo XDP e alla policy creata in precedenza.

FsxId05f7f00af49dc7a3e::> snapmirror create -source-path sapcc-hana-svm:PFX_data_mnt00001 -destination-path sapcc-backup-target-zone5:PFX_data_mnt00001 -vserver sapcc-backup-target-zone5 -throttle unlimited -identity-preserve false -type XDP -policy snapcenter-policy
Operation succeeded: snapmirror create for the relationship with destination "sapcc-backup-target-zone5:PFX_data_mnt00001".

Inizializzare SnapMirror

Con questo comando, viene avviata la replica iniziale. Si tratta di un trasferimento completo di tutti i dati dal volume di origine al volume di destinazione.

FsxId05f7f00af49dc7a3e::> snapmirror initialize -destination-path sapcc-backup-target-zone5:PFX_data_mnt00001 -source-path sapcc-hana-svm:PFX_data_mnt00001
Operation is queued: snapmirror initialize of destination "sapcc-backup-target-zone5:PFX_data_mnt00001".

È possibile controllare lo stato della replica con snapmirror show comando.

FsxId05f7f00af49dc7a3e::> snapmirror show
