The following steps include command examples.
Note: For a full explanation of the command structure, see Dell Solutions Enabler SRDF Family: CLI User Guide provides.
symsnapvx –sid 790 –sg HANA_SG_R1 –name SnapVX_SNAPSHOT establish
To display the snapshot details, run:
symsnapvx –sid 790 list –sg HANA_SG_R1 -detail
To display the snapshot state:
symsnapvx –sid 790 list –sg HANA_SG_R1 -summary
The state of the devices should be Established.
symsnapvx –sid 790 –sg HANA_SG_R1 –name SnapVX_SNAPSHOT establish
Note: If SnapVX fails to create a snapshot on any volume in the storage group, the command will fail for all devices in the storage group.
To display the snapshot details, run:
symsnapvx –sid 790 list –sg HANA_SG_R1 -detail
To display the snapshot state, run:
symsnapvx –sid 790 list –sg HANA_SG_R1 -summary
The state of the devices should be Established.
Note: You can have multiple snapshots of the same name for the same set of source devices, with generation numbers to identify the different snapshots. For more information, see Dell EMC PowerMax and VMAX All Flash: SnapVX Local Replication.
symsnapvx –sid 790 –sg HANA_SG_R1 –lnsg HANA_LNK_TGT –snapshot_name SnapVX_SNAPSHOT –gen 1 link -copy
To display the snapshot details, run:
symsnapvx –sid 790 list –sg HANA_SG_R1 -detail
To display the snapshot state, run:
symsnapvx –sid 790 list –sg HANA_SG_R1 -linked -lnsg HANA_LNK_TGT -detail
The state of the devices should be CopyInProg.
Start the SAP HANA database at the local site by using the linked target clone devices. Unlike the SAP HANA storage snapshot process, SAP HANA will go through a recovery process once it starts, similar to a restart after a power failure.
Note: You can also include an SAP HANA storage snapshot for a single container database and use it for rapid database recovery on the local site to recover to a specific point in time, optionally using log backups. SAP HANA storage snapshots currently do not support multitenant database containers with SPS 09 or SPS 10, however; therefore, SnapVX consistent clones are recommended in this scenario.
