Note: You should begin the commissioning process by selecting a blueprint in the Blueprint tab.
In the Storage tab, you can do the following:
Configure Internal Storage
Under the Boot LUN section, and under Internal Storage, select the appropriate LUN size in the LUN Size – No. drop-down list.
LUNs are identified by the ID number. For example, ID1, ID2, and so on. Once you select a LUN as the Boot LUN, it will not be available for selection as a Data LUN.
The following list provides general guidelines on the minimum internal storage that you may want to choose, depending on your OS and External Storage selection. The storage sizes listed below are indicative only and the LUN size may need to be increased depending on the amount of memory that you assigned to the partition image. For example, if you assign 3 TB of memory to the partition image, then a LUN size of 110 GB is required:
A LUN size of at least 60 GB if you are commissioning a Windows partition image from Unisys-supplied images, and the boot volume is on internal storage.
A LUN size of at least 20 GB if you are commissioning a Linux partition image from Unisys-supplied images, and the boot volume is on internal storage.
A LUN of at least the size of the original disk size that the operating system you captured is installed on if you are commissioning a Linux partition image from customer-supplied images, and the boot volume is on internal storage.
A LUN of the smallest disk size (for example, 1 GB) for containing necessary drivers, if the boot volume is on external storage and you will be configuring your partition to boot from an external storage device over fibre channel.
A LUN size of at least 20 GB if you are commissioning a Linux partition image that you will be configuring to boot from an external storage device over iSCSI.
Configure External Storage
If you have selected an HBA port in the I/O Ports tab, then you can configure the partition image to use an external storage as a boot LUN using the following options:
Configure using Partition Image Console: Choose this option if you wish to configure the external storage using the partition image console.
If you choose this option, then you must select the Target Boot LUN when you install the OS using the partition image console. To know more about selecting the external Boot LUN using the partition image console, see the ClearPath Forward Installation and Getting Started Guide.
Configure Target Boot LUN Now: Choose this option if you wish to configure the external storage using the Fabric Manager. If you choose this option, provide appropriate values in the following fields:
Target WWPN: Type the WWPN address in hexadecimal format. For example, 11:22:33:44:AB:CD:EF:AD.
Target LUN No.: Type the target LUN number. This number should be between 0 and 255.
Primary Boot Path: Select the path that you want to assign as the primary boot path. The default value is the HBA port that you have selected.
Notes:
Ensure that your storage administrator configures the LUN on the external storage device appropriately, factoring in the operating system vendor requirements, operating system, and the application configurations in blueprint and gold image, partition memory configuration, and so on. Refer to Windows and Linux documentation to determine an appropriate LUN size.
At any point of time, if you wish to decommission this partition image you should erase the content of the external LUN. To know more about erasing the content of an external LUN, see the ClearPath Forward Security Guide.
Configure Data LUN
You can configure a LUN of an appropriate size as the data LUN for the partition image. To do this, under the Data LUN section and under Internal Storage, select the appropriate LUN. You can choose multiple LUNs.
Notes:
You can assign up to 7 Data LUNs for a partition image.
At any point of time, if you wish to decommission this partition image and need a backup of the data on these LUNs, you should request the administrator to create a manual backup of these LUNs and then erase the contents of the LUN.
If you are commissioning a Windows partition image, you must bring the associated data LUNs online after commissioning the partition image.
If you are commissioning a Linux partition image, you must mount the associated data LUNs After commissioning the partition image.
