The Oracle MaxRep for SAN provides a variety of tools to administer the LUNs that are managed by the Oracle MaxRep Replication Engine.

The following LUN management tools are available from the Toolkit for

MaxRep option on the Settings tab:

Map Allows you to map retention and home LUNs of the registered Oracle FS System to the Replication Engine.

Unmap Allows you to remove the mapping configuration between the registered Oracle FS System and the Replication Engine. You cannot use this option to remove the mappings on a LUN that is a member of protection plan.

Detect Resize After you have resized a LUN that is associated with a replication pair, this option allows you to adjust the size of your LUNs in your protection plan.

Clear Write Splits Allows you to clear the write split on a LUN that cannot be

used in a protection plan. Related Links

Map LUNs

Use the Map LUNs feature to map retention, backup, and optional home LUNs. You can also map LUNs that are used for any physical backup copies of a

replicated pair.

Note: The Map LUN feature is not used to map source or target LUNs that are used in replication pairs. These LUNs are mapped automatically during the Create Protection Plan process.

Before you map a LUN, consider the following points:

• When mapping a LUN, the Oracle FS System deletes any existing host mappings for the LUN.

• Oracle MaxRep for SAN supports third- and fourth-level Linux file systems (ext3 and ext4). The Linux operating system journals the file system so that these file systems might be recovered in the event of data corruption.

• A LUN is always mapped to an appliance initiator for the target (AIT) port group. The AIT port group is used to access the retention and backup LUNs, and optionally the home LUNs, that are mounted on the Replication Engine.

You can format and mount a LUN, mount the LUN if it is already formatted, or map and initiate the scanning from Oracle MaxRep for SAN.

1 Navigate to Settings > Oracle Storage > Toolkit for MaxRep. 2 In the Select MaxRep Option page, select Map and click Next. 3 From the Select Oracle Storage list, choose the Oracle FS System

containing the LUN that you want to map.

4 Select the Replication Engine from the Select MaxRep list. The Select LUNs for Mapping table lists the available LUNs. 5 Expand the entry for the Oracle FS System containing the LUN. 6 Select the LUNs for mapping and click Next.

A warning message displays stating that if the LUN is already mapped, your actions unmaps the selected LUN.

7 For locally-used LUNs, such as retention, backup, or an optional home file system, provide the Mount Point path. After mapping the LUN, the

system mounts the LUN to the provided path.

8 Specify the Format Required option. Select this option if you want the system to format the LUN after mapping.

Note: A LUN must be formatted to mount properly.

Caution: Formatting removes any filesystem data from the LUN.

9 For locally-used LUNs, such as retention, backup, or an optional home file system, specify whether to Map to Physical FC Ports.

Note: We recommend this option for the retention, backup, and optional home LUNs.

10 Select the Filesystem protocol that is support by the operating system. Note: We recommend that you use the preferred file system (ext4) for local

(retention, backup, and optional home) LUNs. 11 To initiate the mapping, click Submit.

Unmap LUNs

Use the Unmap option to remove LUN mappings from the Oracle MaxRep Replication Engine.

The Oracle MaxRep Replication Engine lists the LUNs that meet the following criteria:

• LUNs that are mapped using the Map LUN option from the Toolkit for MaxRep.

• LUNs that are not members of a protection plan.

1 Navigate to Settings > Oracle Storage > Toolkit for MaxRep. 2 In the Select MaxRep Option page, select Unmap and click Next. 3 From the Select Oracle Storage list, choose the Oracle FS System

containing the LUN that you want to unmap.

7 Click Submit.

Detect Resizing of the Home and Retention LUNs

Oracle MaxRep for SAN allows you to scan the retention and home LUNs for capacity changes and reflect those changes in the protection plans.

1 Navigate to Settings > Oracle Storage > Toolkit for MaxRep.

2 In the Select MaxRep Option page, select Detect Resize and click Next. 3 From the Select Oracle Storage list, select the Oracle FS System that

contains the source LUN for the replication pair to be resized. 4 Expand the entry for the Oracle FS System containing the LUN. 5 From the LUN navigation tree, select the home or retention LUN.

Tip: Click the + sign to expand the list of available LUNs.

Note: The Select LUN Scan Options table only lists the LUNs that are used in replication pairs.

6 After selecting the LUN, click Next.

7 Confirm that the correct LUN is selected, and then click Submit.

The system displays the Policy History for LUN Resize page.

8 Verify that the Policy History status shows Pending, followed by Success. 9 Click the Monitor tab and review the Alerts and Notifications for possible

errors.

LUN Management

Detect Resizing of a Source LUN

Modifying the size of the source LUN requires that you update the source LUN size in your protection plan. Use the Toolkit for MaxRep to adjust the size of the source LUN of your protection plan.

When resizing replication pair LUNs, resize the LUNs in the following order: • Resize the target LUNs

• Detect the target LUN resize in the Oracle MaxRep for SAN GUI • Resize the source LUN

• Detect the source LUN resize in the GUI

Modify the size of your LUN by following the procedure that is described in the

Oracle Flash Storage System Administrator’s Guide.

1 Navigate to Settings > Oracle Storage > Toolkit for MaxRep.

2 In the Select MaxRep Option page, select Detect Resize and click Next. 3 From the Select Oracle Storage list, select the Oracle FS System that

contains the source LUN for the replication pair to be resized. 4 Expand the entry for the Oracle FS System containing the LUN.

5 From the LUN navigation tree, select the source LUN of the replication pair.

Tip: Click the + sign to expand the list of available LUNs. 6 After selecting the LUN, click Next.

7 Confirm that the correct LUN is selected, and then click Submit.

The system displays the Policy History for LUN Resize page.

8 Verify that the Policy History status shows Pending, followed by Success. 9 Click the Monitor tab and review the Alerts and Notifications for possible

errors.

If the system displays the following error, then follow the procedure to resize and detect the resize of the target LUN.

The source Devices (/dev/mapper/...) has been reconfigured upon resize and the following replication pair is paused. Please resize your target LUN to greater than or equal to the source LUN and then resume the replication pair.
