You have a p5 or p6 which has been running fine for 2, 3 or 4 years but new applications or business expansion mean you're getting a brand new server as well. You have an HMC which is fairly up to date. How quickly can you get the server going, ready to install your first LPAR?
E.T.A.: "pretty quickly"
Assuming you've done your homework on sizing the system, cabling and power needs etc, you can get your system online pretty quickly.
- Rack-mount the server. This should be by far the slowest step. The reason is simple: you can't virtualise a rack.
- Connect it to power.
- Connect cable to the HMC. This may be a direct connection to the HMC, or better still to a switch.
- Log onto HMC and "Add Managed System." You may use DHCP to discover the server.
- Power on server via the HMC.
- Update System Firmware if you need to. HMC and System firmware updates can be found at the IBM Support Portal.
You may need to connect cables to storage, once again probably via a switch rather than directly to the storage subsystem. You will also have to Create Logical Partitions and either build them from scratch or restore via a mksysb.
It's always fun powering on a brand new server. It's not difficult at all and it's a chance to get familiar with the new technology before it has to be installed for its real job - not your playground, but the benefit of the business.
