使用在 7- 模式下运行的 Data ONTAP 在主存储发生故障后还原数据库

提供者 下载此页面的 PDF

在运行 7- 模式 Data ONTAP 的主存储系统出现故障后,您可以还原 SAP HANA 数据库。

  1. 在这种情况下,必须使用以下命令在二级存储系统上直接执行还原: SnapVault restore -s snapshot_name -S backup_controller : backup_volumesource_controller : source_volume

    对属于 SAP HANA 数据库的所有卷执行此步骤。

    hana1a>  snapvault restore -s Backup-ANA-SV_hourly_20140410103943 -S
    hana2b:/vol/backup_data_00001/mnt00001 hana1a:/vol/data_00001/mnt00001
    Restore will overwrite existing data in /vol/data_00001/mnt00001.
    Are you sure you want to continue? y
    Thu Apr 10 11:55:55 CEST [hana1a:vdisk.qtreePreserveComplete:info]: Qtree preserve is complete for /vol/data_00001/mnt00001.
    Transfer started.
    Monitor progress with 'snapvault status' or the snapmirror log.
    hana1a>  snapvault restore -s Backup-ANA-SV_hourly_20140410103943 -S
    hana2b:/vol/backup_data_00003/mnt00003 hana1a:/vol/data_00003/mnt00003
    Restore will overwrite existing data in /vol/data_00003/mnt00003.
    Are you sure you want to continue? y
    Thu Apr 10 11:58:18 CEST [hana1a:vdisk.qtreePreserveComplete:info]: Qtree preserve is complete for /vol/data_00003/mnt00003.
    Transfer started.
    Monitor progress with 'snapvault status' or the snapmirror log.
    hana1b>  snapvault restore -s Backup-ANA-SV_hourly_20140410103943 -S
    hana2b:/vol/backup_data_00002/mnt00002 hana1b:/vol/data_00002/mnt00002
    Restore will overwrite existing data in /vol/data_00002/mnt00002.
    Are you sure you want to continue? y
    Thu Apr 10 12:01:29 CEST [hana1b:vdisk.qtreePreserveComplete:info]: Qtree preserve is complete for /vol/data_00002/mnt00002.
    Transfer started.
    Monitor progress with 'snapvault status' or the snapmirror log.

    还原过程完成后,您可以使用 SAP HANA 执行恢复。
