Cree un volumen de destino

Debe crear el volumen objetivo con el tipo DP para marcarla como un destino de replicación.

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

Cree una política de SnapMirror

La política de SnapMirror y la regla añadida definen la retención y la etiqueta de SnapMirror para identificar los Snapshots que deben replicarse. Al crear la política de SnapCenter más adelante, debe usar la misma etiqueta.

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

Crear una relación de SnapMirror

Ahora se define la relación entre el volumen de origen y el de destino, así como el tipo XDP y la política que hemos creado anteriormente.

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".

Inicializar SnapMirror

Con este comando, se inicia la replicación inicial. Esta es una transferencia completa de todos los datos del volumen de origen al volumen objetivo.

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".

Puede comprobar el estado de la replicación con el snapmirror show comando.
