Using the Fabric Manager, you can resize partition images in the following situations:
The allocated resources (memory size, processor, cores, and IO ports) for a partition image are not sufficient.
The allocated resources (memory size, processor cores, and IO ports) for a partition image are under-utilized.
The number of Data LUNs allocated to the partition need to be increased or decreased.
Recommendations
Back up your data before resizing a partition image. It prevents loss of data from any catastrophic failures during the resizing process. to know more about the backup procedures.
Resize the partition image if the existing setup currently causes problems or may cause problems soon. For example, the partition image has utilized the memory space completely or is expected to add enough data to overfill.
For more information, see Planning Your Partitions.
When releasing a Data LUN from the partition, ensure that you clear the data on the LUN.
In rare situations, the resizing operation might fail and you might encounter the following errors based on the operating system that you have installed on the partition image that is being resized:
If you have installed Linux operating system on the partition image, then after performing the resizing operation, the operating system continuously displays the message “Starting”.
If you have installed Windows operating system on the partition image, then after performing the resizing operation, the operating system continuously displays the message “The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed".
The reason for this can be:
Improper installation of the operating system on the partition image that is being resized
Unorderly shutdown of the partition image before commencing the resizing operation
To avoid this situation, before beginning the resizing operation, ensure that
The operating system has been properly installed on the partition image
The partition image has been orderly shutdown using the Soft Shutdown option
Prerequisites
Required additional resources are available on the platform.
The partition image should be in Stopped state.
Note: It is recommended to perform soft-shutdown and not force-halt the partition image.
Note: Note:You might encounter Secure Fabric BDF conflicts after resizing the partition image.
To resize a partition image
On the Fabric Manager user interface, point to System Administration, and then click CPF System.
Click Platforms and Partitions.
The Details: Platforms and Partitions screen appears on the right pane.
Expand the desired platform, and then click the partition image to resize and edit the attributes.
In the Details pane, click Edit.
Alternatively, click the arrow next to the partition image and click Edit.
The Edit Partition Image window appears.
In the Partition Attributes tab, based on the partition image state, you can edit following fields:
If the partition image is in running state, you can edit Partition Name, Partition Description, and Initial state on platform reboot fields.
If the partition image is in stopped state, you can edit Partition Name, Partition Description, Cores, Memory, Enable Hyper Threading, and Initial state on platform reboot fields
Click Next.
In the Cores & Memory tab, you can edit the Chassis, Cores and Memory fields.
In the I/O Port Details tab, you can do the following:
Assign/ Disable/Release the Dedicated NIC ports.
Assign/Disable/Release logical ports.
Enable or disable NIC Teaming on logical ports.
Enable or disable Peer Forwarding on logical ports.
Assign/Disable/Release the HBA ports.
To know more about assigning, disabling or releasing ports, see Commissioning a Partition Image.
In the Secure Fabric tab, you can do the following:
You can select new secure fabrics to associate with the partition image, or clear the previous selection of secure fabrics to disassociate them from the partition image.
(Optional) You can enable the FM-LAN by selecting the FM-LAN check box. Once enabled, the health of the partition changes to Ok, Warning or Unknown.
If you have already enabled the FM-LAN, you can disable it by clearing the FM-LAN check box and the health of the partition changes to Monitoring Disabled (FM-LAN Disabled).
CautionBefore you enable the FM-LAN option, it is important that you understand the security risks associated with the use of the FM LAN. It is possible for an FM LAN Ethernet switch monitored by the Fabric Manager to have an access vulnerability. For more information on the security risks associated with the FM LAN, see Enabling and Disabling the FM LAN.
In the Storage tab, you can change the previous selections of Data LUNs.
Click Save.
The selected partition image is resized and turns to Stopped state. You can verify if the resized partition image is operational by starting it.
Notes:
Do not perform any other action on the platform till the partition image reaches Stopped state.
Events for initiation and completion are logged and displayed in the event console.
