11 Redundant VIOS Virtual Servers hosting IBM i

For a production IBM i virtual server hosted by VIOS, you want redundant VIOS virtual

servers in case of failures or scheduled maintenance on the hosting VIOS virtual server.

IVM cannot be used since it is actually running in VIOS and can only manage that virtual

server. For a Power server or a POWER blade, either an HMC or an SDMC can be used.

You need to consider the following steps for the configuration of this environment.

 Create two VIOS virtual servers/LPARs using SDMC/HMC. Allocate processor,

memory, network adapters and storage adapters for each. For SDMC use the

IBM Systems Director Management Console: Introduction and Overview from

IBM Redbooks at: http://www.redbooks.ibm.com/abstracts/sg247860.html?Open

 Create an IBM i virtual server/LPAR using SDMC/HMC. Allocate processor and,

memory. The networking and storage are typically virtualized, but physical

adapters can be assigned. If you are considering moving to IBM i hibernation and

eventually to LPM, you should make the virtual server/LPAR fully virtualized

hardware and host it with VIOS.

 You need shared storage for IBM i that both VIOS virtual servers/LPARs can

access. This implies a SAN as integrated disks cannot share access. Review the

concepts explained in the “Storage virtualization” section. Select either a VSCSI

or virtual FC configuration for the shared storage.

 For networking considerations, see section “Redundant VIOS Networking”.
