Adding a LUN
This section describes how to add a LUN to a PG.
Prerequisites
The members of the PG are LUNs.
If the members in a protection group are LUN groups, choose Services > Block Service > LUN Groups, select a LUN group to which you want to add a LUN, and add a LUN to the LUN group as instructed. For details, see Adding a LUN in the Basic Storage Service Configuration Guide for Block specific to your product model and version. The related parameters are described as follows:
- Automatic: The storage system automatically creates a remote LUN group and remote LUNs on a remote device for the LUN group and its member LUNs. Ensure that LUNs in the LUN group are not used to create remote replication pairs. If a remote LUN or a remote replication pair already exists, use manual creation mode to create remote replication pairs. Otherwise, a configuration conflict may occur.
- Manual: Select the same number of LUN groups with the same capacity per LUN group and match the member LUNs between the local and remote devices. Ensure that LUN groups and member LUNs on the remote device are not mapped. Otherwise, a configuration conflict may occur.
- Run Later: If this function is enabled and a new remote replication pair is being synchronized, the storage system will add the new remote replication pair to a CG after synchronization.
Procedure
- Choose Data Protection > Protection Entities > Protection Groups > Protection Groups.
- Click More on the right of a PG and select Add LUN.
The Add LUN page is displayed on the right.
Alternatively, perform any of the following operations to go to the Add LUN page:
- Click the name of the desired PG. In the upper right corner of the page that is displayed, select Add LUN from the Operation drop-down list.
- Click the name of the desired PG. On the page that is displayed, click the Members tab and then click Add.
- Click the value in the LUNs column of the desired PG if the value is not 0. On the Members tab page, click Add.
- Add LUNs to the PG.
- If no remote replication is created for the PG:
In the Available LUNs area, select one or more LUNs.
- If remote replication has been created for the PG:
- Add objects.
- In the Available LUNs area, select one or more LUNs.
- Click Next.
- Configure a remote replication pair. Select or deselect Run Later as required.
If this option is selected when you configure a remote replication pair, the system waits for the new pair to complete synchronization (if the new pair is synchronizing) and then adds it to the CG.
- Click Next.
- Add objects.
- If no remote replication is created for the PG:
- Click OK.
