Considerations for a backup console
Many system plans include a level of redundancy to allow for hardware failures, but some do not consider the console in those plans.
Consider the following items when planning for a backup console.
- Consider using the takeover and recovery function as part of your backup console strategy. However, the hardware used for the Operations Console must be installed prior to the recovery.
- If your system is managed by a Hardware Management Console (HMC), you can tag a Host Ethernet Adapter logical port or an IOA as the console device.
- On large multi-partitioned systems or high-availability systems, use Operations Console (LAN) as the system console for each system or logical partition. In the event of a console failure, you can switch to the HMC 5250 console without having to verify you have additional hardware in place. Most changes of a console to HMC are performed without the need for an IPL.
