Allocate a Management Server to manage the operation side device and the standby side device. Register the operation side device and the standby side device in the Management Server.
NAS management is implemented in the same way as on the operation side device. For prior settings and the installation procedure for performing a NAS operation, refer to "NAS Management" in the Storage Cruiser Operation Guide or Express Operation Guide.
Create a NAS volume and a NAS backup volume in the operation side device and standby side device.
Create a NAS volume according to the installation procedure for the NAS operation.
Refer to "NAS Management" in the Storage Cruiser Operation Guide or Express Operation Guide for the installation procedure to perform a NAS operation.
Perform a NAS backup setting to create a NAS backup volume.
Refer to "Set NAS Backup" in the Web Console Guide for the procedure to create a NAS backup volume.
Create the following three copy groups.
Copy Group / Copy Pair | Creation Method | Copy Type |
|---|---|---|
Copy group of the NAS volume and the NAS backup volume (in the operation side device) | NAS backup settings | QuickOPC |
Copy group of the NAS volume and the NAS backup volume (in the standby side device) | NAS backup settings | QuickOPC |
NAS backup volume (in the operation side device) and NAS backup volume (in the standby side device) copy group | Execute the acgroup create command | REC |
Point
When performing a standby operation between different sites, allocate a Management Server in each site. In order to make all operation procedures executable in each Management Server, register all the copy groups/copy pairs.
Use the Stack mode for the REC data transmission mode.
When backing up to a tape to use the REC initial copy skip function, a direct backup to a tape from the NAS volume or the NAS backup volume is not available. Back up to a tape from a different secondary backup volume. Refer to "3.10.5 Concerning Secondary Backup of NAS Volume and Use of Data on Different Storage Devices" for the secondary backup of the NAS volume.
Before backing up the NAS volume in the operation side, use the following procedures to back up the NAS volume in the standby side.
Back up the NAS volume in the standby side using Web Console or the acnas backup command. Refer to "3.10.1.2 How to Execute Backup" for backups using Web Console and "3.10.2.2 How to Execute Backup Commands" for backups using the acnas backup command.
Stop QuickOPC that is copying from the NAS volume to the NAS backup volume in the standby side (stop the physical copy and Tracking processing).
Point
If you perform a standby operation using the sample scripts for automating the operations, the above steps are unnecessary. Refer to "F.4 Automation of Operation" for details when using the sample script.
