Double click on Server and Partition
You will get the below screen. Under Servers and Partitions all the frames managed by that HMC exists .In the below snapshot you can see P570, P590
frames
Right click on the frame on which you are going to create a new LPAR
Click on Create-->logical partition
The following screen appears
Partition ID is automatically generated. Partition ID is a numeric value between 1 and 254
Partition Name is the server name (example “system” here). Partition environment must be AIX or Linux
Enter the partition name and click next
If you want to use workload partition group you can select “yes “.Here the LPAR we are going to build doesn’t uses any WLM so select No and click next
Each logical partition requires at least one partition profile. The profile name can contain up to 31 characters (string). For more information you can read a Partition profile concept which is explained in the beginning of the document.
Here we are giving profile name same as the partition name i.e. “system”.Click next
You will get memory selection window. Here we have to give the minimum, desired and maximum memory capacity for the partition.
• Desired memory: This is the requested amount of memory for the partition, and if available system will boot with this amount of memory.
• Maximum memory: The maximum represents the upper limit for memory.
• Minimum memory: This amount of memory is required for the partition to boot. The profile will fail to activate if the minimum memory is not met.
After entering the memory details click next.
The processor capacity in a frame is divided in to
1) Dedicated processors
2) Processor shared pool.
If we want to build an LPAR with dedicated processor, we have to select “dedicated “in the following screen. Processors assigned to a dedicated partition can not be used by any other partition while it is running.Here we are going to build a LPAR which is going to have shared processor. So we will select “shared” option
Clicking next will give you processors settings window as below
The Desired processing value is the amount of processing resources that the partition will require to boot Maximum processing value is the maximum amount of processing resources that the partition will get, even if there are manual attempts to assign the partition more processing power.Minimum processing units needed to start up the partition.
Click Advanced for Advanced processor settings
CAPPED & UNCAPPED
POWER5 partitions in the shared processing pool can have a sharing mode of capped or uncapped.
• A capped partition indicates that the logical partition will never exceed its assigned processing capacity.
• An uncapped partition means that the partition’s assigned current processing capacity may be exceeded, up to the partition’s maximum virtual processors settings, when the shared processing pool has any unused processing power.
• Uncapped weight is a number in the range of 0 through 255 that you set for each uncapped partition in the shared processing pool. Default weight is 128
• 255 being the highest priority and 0 being the lowest priority, i.e. a LPAR with higher uncapped weight will get priority to the processing pool Virtual processor settings are generated by default. Change the virtual processor settings according to specification. To know more about virtual processors please
read the explanation about virtual processors in the beginning of the document.
This screen did not come for dedicated Processor LPARs since processors allocated to an LPAR cannot be used by any other LPAR.
Select Uncapped and give virtual processor values.
Click next to get I/O selection window.
I/O resources can be dedicated to an LPAR or shared between LPARS.
One way of sharing I/O adapters is assigning the adapters to vio server and from there let LPARs share the adapter through Virtual LAN.
This can be accomplished by defining virtual adapters in the LPARs.
If we are using any dedicated IO resource we can select the corresponding IO resource in the above screen otherwise if you are using vio server then click next without any selection .
For the LPAR we are going to build we use VIO servers for IO resource so click next without any selection No need of adding any I/O pool for the LPAR we are going to build. Click next
We have to configure virtual I/O adapters for the LPAR we are building so Select option “yes”.
Click next
We will get Virtual adapters settings window
There are three types of virtual adapters we can configure
Virtual SCSI
Virtual Ethernet
Virtual Serial
First we will configure the virtual Ethernet adapters.
Virtual Ethernet adapter allows for high speed (1 gigabit) inter-partition
communications.
Select Ethernet Tab to configure Ethernet adapters and click on Create adapter
option.
We will get a virtual Ethernet adapter configuration window as below
The slot number refers to the position of the virtual Ethernet adapter on the virtual system bus.
Port virtual LAN ID is analogous to the current virtual LAN/Ethernet ID
Provide Slot number and Virtual LAN ID in the corresponding entry tabs. (For example here 2 is slot number and 1 is VLAN ID)
Select the corresponding VLAN ID in the System VLAN tab.
Click OK.
One virtual Ethernet adapter will get created and I t will showing in the contents as showed in the following screen.
Ethernet adapters marked as “Required” will be reserved for the exclusive use of this partition, and cannot be accidentally moved through dynamic LPAR.
A required resource is needed for the partition to start when the profile is activated.
Check “Required” on all Virtual Ethernet adapters and enter the number higher than the final VLAN number in Maximum virtual adapters field. Click next
The HMC by default gets power control partition, the ability to power the partition on and off.
If you have any specific power control partition you can add.
Click Next
Select SMS for boot modes & Click Next
Confirm the summary of the profile and configuration from the below screen
Click Finish.
It will start creating the partition. Following pop up shows LPAR creation is in
Process.
After the creation of partition it will be showing as not activated in the HMC with the profile created as shown below
