What is Vio in AIX?

What is Vio in AIX?

Virtual I/O (VIO) server is a virtualization technology by IBM. A Virtual I/O server is a logical partition (LPAR) that runs a trimmed-down version of the AIX operating system. Virtual I/O servers have APV support, which allows sharing of physical I/O resources between virtual I/O clients.

Is Vios a hypervisor?

VIOS is not a hypervisor, nor is it required for sub-CPU virtualization. VIOS can be used to manage other partitions in some situations when a HMC is not used. This is called IVM (Integrated Virtualization Manager). Depending on configurations, VIOS may or may not be a single point of failure.

How do I create a virtual Ethernet adapter in AIX?

Click the Virtual Adapters tab. Click Actions > Create > Ethernet adapter. Select IEEE 802.1Q-compatible adapter. If you are using multiple VLANs, add any additional VLAN IDs for the client logical partitions that must communicate with the external network through this virtual adapter.

What is HMC in AIX?

The HMC provides a graphical interface to control servers, including powering up and down, and setting up and managing partitions running on the managed servers. On AIX® or Linux partitions, this is accomplished through the HMC graphical user interface (GUI) and through the virtual terminal.

What is VLAN AIX?

A VLAN splits up groups of network users on a real physical network onto segments of logical networks. This implementation supports the IEEE 802.1Q VLAN tagging standard with the capability to support multiple VLAN IDs running on Ethernet adapters.

How do I create a virtual Ethernet adapter?

Virtual Ethernet provides Ethernet connectivity between partitions….Creating a virtual Ethernet adapter

1. In the Virtual Ethernet Adapters section, click Create Adapter.
2. Enter the Virtual Ethernet ID and click OK to exit the Enter Virtual Ethernet ID window.
3. Click OK to exit the Partition Properties window.

What is Npiv in AIX?

NPIV enables the AIX VIO server to provision entire dedicated logical ports to client mLPARs rather than individual LUNs. Client partitions with this type of logical port operates as though the partition has its own dedicated FC protocol adapter.

Is LPAR same as VM?

Power Systems uses the term Logical Partition (LPAR), which is a vague non-descriptive term and the rest of the computing world uses Virtual Machine (VM).

What is LPAR in AIX?

LPAR comes as a kernel module, with a set of user space utilities to create and manage logical partitions (LPARs). IBM LPAR virtualization technology includes the following: IBM LPAR virtualization technology.

What is Vio upgrade?

VIOS 3.1 Upgrade process IO virtualization includes several configurations to virtual and physical devices, virtual device to physical device mappings and hosting virtual and physical devices drivers.

How do I update my VIO server?

You need to perform the following steps to update VIOS to a later level.

1. Prepare for the update.
2. Clone and update VIOS.
3. Perform post-update process on the existing VIOS level.
4. Restart VIOS.
5. Perform post-update process on the new VIOS level.
