Moving the MSDP partition from a base disk to an expansion disk for optimum performance
The following procedures explain how to move the MSDP partition from a base disk to an expansion disk. The base disk resides on the appliance base unit. The expansion disk resides on a storage shelf that is attached to the appliance.
Consider the following scenarios:
Scenario 1 - The MSDP and AdvancedDisk partitions are configured on the base disk. The expansion units are physically attached to the appliance but have not been added yet.
Scenario 2 - The MSDP partition exists on the base disk. The expansion units are configured and partitions exist on them.
Select the scenario that applies to you and follow the appropriate procedure outlined below.
Scenario 1 - To move the MSDP partition from a base disk to an expansion disk
- Log on to the NetBackup Appliance Web Console.
- Click Manage > Storage and go to Disks section. Check the partitions that are on the Base disk. Suppose that you have MSDP, MSDP Catalog, AdvancedDisk, NetBackup Catalog, and Configuration partitions on the base disk.
Note:
If you have added storage shelves, click the Scan button to scan the new storage to create RAID volumes and add the new shelf to the unallocated storage.
See Adding the disk space of additional storage shelves from the NetBackup Appliance Shell Menu.
See Adding the disk space of additional storage shelves from the NetBackup Appliance Web Console.
- Ensure that the base disk is fully allocated by resizing the non-MSDP partitions (like AdvancedDisk). To ensure that the base disk is full, resize the AdvancedDisk partition to a value that is just below the maximum value.
In the Partition section, click AdvancedDisk partition to open the partition details page.
On the partition details page, click Resize in the Partition Distributions on Disk section. Enter a size in the New Size field that is slightly below the maximum value.
Click Resize to resize. In this example, the AdvancedDisk partition is being resized to 22.9 GB. The maximum value that it can be resized to is 23 GB.
Click OK after the resize operation is complete. The page is refreshed automatically and reflects the updated size.
- In the Disks section, click the Add link. Click Yes to confirm the addition and OK when it finishes. Repeat this process for the second expansion unit.
Note that the Unallocated space increases.
- Check the space occupied by MSDP partition and how the MSDP partition is distributed across disks..
In the Partition section, click the MSDP link to open the MSDP partition detail page.
On MSDP partition detail page, check the Partition Distributions on Disk section.
In this example, all of the MSDP partition resides on the base disk and occupies 5 GB.
Note that the expansion disk must have at least 5 GB of unallocated space when you move the MSDP partition to the expansion disk at a later point.
- Click Move in the Partition Distributions on Disk section.
- The Move Partition window is displayed. Select the target disk from the drop-down list to which you want to move the partition.
In this example, all of the MSDP partition that resides on the base disk is moved to one expansion disk.
- Click Move to move the partition.
Note:
The partition size and the workload on the system determine the time it takes to move a partition.
- Dialogs in the Move Partition displays the progress details and status of the move operation. Click OK once the operation is complete. The MSDP detail page is automatically refreshed.
- On the MSDP detail page, check the Partition Distributions on Disk section. The MSDP partition resides on the expansion disk.
The following procedure explains how to move the MSDP partition from a base disk to an expansion disk when the expansion disk has partitions configured on it.
Scenario 2 - To move the MSDP partition from a base disk to an expansion disk
- Log on to the NetBackup Appliance Web Console.
- Click Manage > Storage .
In the Partition area, click MSDP to go to the MSDP detail page.
- On the MSDP partition detail page, check the Partition Distributions on Disk section.
If the Type is Base for any of the disks, all or a part of the MSDP partition resides on the base disk. In this example, the MSDP partition is located on the base disk as well as the expansion disk.
If the type is Expansion for all the disks, the MSDP partition doesn't exist on the base disk. In this case, you do not need to move the MSDP partition. You can ignore the rest of the procedure.
- Click Move in the Partition Distributions on Disk section.
- The Move Partition window is displayed. Select the target disk from the drop-down list to which you want to move the partition.
The target disk must be an expansion disk.
- Click Move to move the partition.
Note:
The partition size and the workload on the system determine the time it takes to move a partition.
- After the operation completes, click OK to close the Move Partition window.
