1) Complete Prerequisites checks.

- Steps a and b can be done at the same time as install when using the GUI methods.

1. VIOS partition and profile should be created.
   
   i.  The Virtual I/O Server logical partition creation can be done either using HMC GUI or by using the HMC CLI as well . For GUI instructions, see Creating the Virtual I/O Server logical partition and partition profile manually by using the HMC
   
   ii. For creating the Virtual I/O server logical partition using HMC Command line interface. You can use the command “mksyscfg" for creation. For CLI instructions, see  HMC Manual Reference Pages - MKSYSCFG
    
2. The install Virtual I/O Server logical partition requires at least one Ethernet adapter, a minimum  of 30 GB disk space, and a minimum of 12Gb memory. Depending on the number and type of IO adapters additional memory may be required; high speed network adapters may require significantly more memory.  Adding additional adapters or disks can lead to longer install times and potential issues. Once install is complete,  additional I/O can be added.  
3. A VIOS image downloaded from ESS either on a NIM server, Imported to the HMC, or on a USB.
4. VIOS installs happen through the HMC's open network and not through the private network [HMC-FSPs]. Ensure these protocols are enabled on the firewall:
   icmp - 5813
rsh - 513 - 1023 TCP
bootp - 67 - 68 UDP
tftp - 69 and 32,768 - 65,535  UDP
nfs - 2049 TCP
mountd - 32,768 - 65,535  TCP
portmapper - 111  UDP 
   
   For more info see Ports and Protocols to be allowed on Firewall for installios
5. You need to have "hmcsuperadmin" authority like for (eg: hscroot)
6. Gather the following information from you network team 
    i. Static IP address for the Virtual I/O Server 
    ii. Subnet mask for the Virtual I/O Server 
    iii. Default gateway for the Virtual I/O Server    

1. In the navigation area, Expand System resources and then select the virtual I/O servers.
   
   
2. Select the newly created virtual I/O server, expand operations and then select the Install VIOS option.
   
   
3. The Install VIOS wizard opens.
4. From the Partition Configuration list, select the required partition configuration profile. You can select only the profile that is associated to the selected partition. When you create a partition a default profile is always associated to the partition. This is indicated with the profile name being followed by default in parentheses. 
   
   
5. Click on next, The VIOS installation configuration tab displayed. 
6. Under installation method , Select Management Console Image and specify the following options: 
   A. From the Management Console IPv4 Address list, select the IP address of the adapter on the management console that you plan to do the NIM or NIMoL of the VIOS. See the pre-req section for network requirements that the chosen adapter's network must have before install.
   B. The installation method will have a few options like NIM Server, Management Console Image, etc. If you have Imported a VIOS image to the HMC, then you can select Management Console Image. 
   C. Under the VIOS network, select an Ethernet adapter port.
   D. Specify the VIOS IP address, the Subnet Mask, and the Default Gateway used to configure the network on the VIOS.
   
   
7.  In the VIOS Installation Configuration tab, click Advanced Settings to view and change the following configuration settings for the selected partition:
   A. From the Adapter Speed list, select the speed of the ethernet adapter for the target partition. By default, Auto is selected to enable the system to determine the required speed of the adapter. 
   B. From the Adapter Duplex list, select duplex value for the Ethernet adapter. By default, Auto is selected to enable the system to determine the required duplex for the adapter. 
   C. From the VLAN Tag Priority list, select the virtual local area network (VLAN) tag priority value to determine the priority of the client partition. You can select the VLAN priority within the range 0 to 7. The default value is 0.   
   D. In the VLAN Tag Identifier field, specify a valid value. The valid value is in the range 1 - 4094.  Note:  If OS vlan tagging is specified the install image must support vlan tagging  or the install will fail part way through. Perform the install using a switch data port  or SR-IOV logical port configured for the desired vlan if the install image does not support OS layer vlan tagging.
8. Click Next. The VIOS Installation Progress tab is displayed. 
9. In the VIOS Installation Progress tab, click Start to start the VIOS software installation on the VIOS. You must accept the VIOS licenses for each VIOS
10. Click Finish to complete the VIOS software installation. The Install VIOS wizard closes.
