4.11 Creating and Deleting Logical Partitions

Partitions can be created in both logical drives (LD) and logical volumes (LV). Depending on your specific needs, you can partition an LD or LV into smaller sizes or just leave it at its default size (that is, one large partition covering the entire LD or LV).

If you intend to map an entire LD or LV to a single host LUN, then partitioning becomes irrelevant. If, however, the LD or LV is to be mapped to multiple host LUNs, then you need to define partitions for later LUN mapping.


NOTE: 

You can create a maximum of eight partitions per logical drive or logical volume. Also, partitioned logical drives can not be part of a logical volume.


Partitioning a logical drive (LD)

1. Display Logical Drives by clicking on the Logical View command button in the introduction or selecting Logical View from the RAID View navigation panel.

2. From Logical View, choose Logical Drives and then the LD that will be partitioned. After you select an LD, the contents panel will display the current View and Edit LD Partition Table.

3. To create a new partition, edit an existing one, or remove an existing partition, click the Edit button. You will be prompted for a password, enter it and click OK.

4. Select partition 0 or the last partition in the list to create a new partition. Only the Size(MB) field is editable and partitions must be contiguous. Modify the value of partition 0 or the last partition so that it will be the size you intend. All unallocated space will automatically be assigned to the new partition.


NOTE: 

Any partition can be modified using the method described here. Changes will be reflected in other partitions as disk space is occupied or freed.


5. If you want to make multiple partitions, repeat the process. If you exit the View and Edit LD Partition Table, you will need to click Edit and enter a password again before you can make changes.

6. To remove partitions, increase the size of partitions higher in the list. Last partitions will always be absorbed first.

The logical drive is now ready for mapping to host LUNs. See: Mapping Logical Drives/Volumes/Partitions to Host LUNs.

Partitioning a logical volume (LV)

1. Display Logical Volumes by clicking on the Logical View command button in the introduction or selecting Logical View from the RAID View navigation panel.

2. From Logical View, choose Logical Volumes and then the LV that will be partitioned. After you select an LV, the contents panel will display the current View and Edit LV Partition Table.

3. To create a new partition, edit an existing one, or remove an existing partition, click the Edit button. You will be prompted for a password, enter it and click OK.

4. Select partition 0 or the last partition in the list to create a new partition. Only the Size(MB) field is editable and partitions must be contiguous. Modify the value of partition 0 or the last partition so that it will be the size you intend. All unallocated space will automatically be assigned to the new partition.


NOTE: 

Any partition can be modified using the method described here. Changes will be reflected in other partitions as disk space is occupied or freed.


5. If you want to make multiple partitions, repeat the process. If you exit the View and Edit LV Partition Table, you will need to click Edit and enter a password again before you can make changes.

6. To remove partitions, increase the size of partitions higher in the list. Last partitions will always be absorbed first.

The logical drive is now ready for mapping to host LUNs. See: Mapping Logical Drives/Volumes/Partitions to Host LUNs.
