4.12 Mapping Logical Drives/Volumnes/Partitions to Host LUNs
After creating a logical drive (LD) or logical volume (LV), you can map it as is to a host LUN; or, if partitions are set, you can map each partition to a specific host LUN. RAIDWatch supports 8 LUNs per host channel (numbered 0 - 7), each of which appears as a single drive letter to the host if mapped to an LD, LV, or a partition of either.
Existing host LUN mappings also can be deleted. In cases where certain mappings are found to be useless, or disk array reconfiguration is needed, you can delete unwanted mappings in your system.
Map an entire logical drive or volume to a host LUN
1. First, be certain that the logical drive or logical volume to map is not partitioned.
2. In the navigation panel under Physical View, click on the host channel where you would like to map a drive or volume.
3. In the sub-navigation window, click on a host channel ID number. The LUN Table for the host channel will be displayed.
4. Choose the LUN Mapping tab, and under the Add sub-tab, choose either LD (for logical drives) or LV (for logical volumes).
5. List the available logical volumes or logical drives by clicking on the "All" icon in the respective window. Click on the drive or volume you would like to map to display its partition 0. Partition 0 should be the only partition listed if you want to map an entire drive or volume to a single LUN.
6. From the LUN Selected drop-box, choose the LUN ID to assign. Only unused IDs will be listed.
7. Next, click on the partition 0 icon. "Partition 0," should appear in the Partition Selected box. Click OK and enter the password when prompted.
8. If you choose the LUN Table, the newly mapped LUN should now be listed.
Map a logical drive or volume partition to a host LUN
1. First, partition the logical drive or logical volume (see section 4.11 above).
2. Once the drive or volume has been partitioned, in the navigation panel under Physical View, click on the host channel where you would like to map partitions.
3. In the sub-navigation window, click on a host channel ID number. The LUN Table for the host channel will be displayed.
4. Choose the LUN Mapping tab, and under the Add sub-tab, choose either LD (for logical drive partitions) or LV (for logical volume partitions).
5. List the available logical volumes or logical drives by clicking on the "All" icon in the respective window. Click on the drive or volume you would like to map to display its partitions. Each drive and volume can have up to 8 partitions, each of which can be mapped to a host LUN.
6. From the LUN Selected drop-box, choose the LUN ID to assign. Only unused IDs will be listed.
7. Next, double-click on the icon of the partition you would like to map. The partition should appear in the Partition Selected box. Click OK and enter the password when prompted.
8. Repeat steps 6 and 7 to map additional partitions.
9. Once all partitions have been mapped, if you choose the LUN Table tab, the newly mapped LUNs should be listed.
Deleting a host LUN mapping
1. In the navigation panel under Physical View, click on the host channel where you would like to delete a host LUN mapping.
2. In the sub-navigation window, click on a host channel ID number. The LUN Table for the host channel will be displayed.
3. Choose the LUN Mapping tab, and then the Delete sub-tab.
4. To delete a LUN mapping, double-click on it in the LUN Map table until the ID is displayed in the LUN Selected box, then click OK. When prompted for a password, enter it and click OK.
5. The LUN mapping should no longer be listed in the LUN Map table. Repeat step 4 to remove additional LUN mappings.
