Which Operating Systems Run on IBM Power6?
IBM Power6 can run IBM i, AIX, and Linux. The Power 520, 550, 570, and 595 reached IBM i 7.2, but that release is now past its final IBM service extension. Match the machine type before planning support or a move.
The operating system is the part of a Power6 decision that gets underestimated. A server can still boot and run its workload while the IBM i release beneath it has already run out of standard support and every service extension.
IBM i support by Power6 machine type
IBM i releases shown in IBM's Power and IBM i model mapping
| Power6 model | Machine type | IBM i releases in IBM's map | Highest release |
|---|---|---|---|
| Power 520 Express | 8203-E4A | V5R4, 6.1, 7.1, 7.2 | IBM i 7.2 |
| Power 550 Express | 8204-E8A | V5R4, 6.1, 7.1, 7.2 | IBM i 7.2 |
| Power 570 | 9117-MMA | V5R4, 6.1, 7.1, 7.2 | IBM i 7.2 |
| Power 595 | 9119-FHA | V5R4, 6.1, 7.1, 7.2 | IBM i 7.2 |
IBM notes that V5R4M5 Licensed Internal Code is required on these Power6 models. Exact device and adapter support still depends on the machine configuration.
IBM i 7.2 ended standard support on April 30, 2021. Its final service extension ended April 30, 2026. A Power6 system at its highest IBM i level no longer has another supported IBM i release it can move to on the same hardware.
AIX and Linux on IBM Power6
Power6 also supports AIX and Linux on selected models. A Power Systems server can run more than one operating system in separate logical partitions through PowerVM. That does not make every release or adapter interchangeable. The exact machine type, firmware level, and I/O configuration decide what is supported.
IBM i
Run DSPSYSVAL QRELEASE to read the installed release. Then match the machine type against IBM's system mapping before planning an upgrade.
AIX
Run oslevel -s for the installed AIX level. Use IBM's model-specific AIX map to check the release and technology level against the exact server.
Linux
Read /etc/os-release inside the partition. Distribution support varies by release and should be checked against that vendor's archived Power requirements.
PowerVM and HMC
Confirm every logical partition, its operating system, and the resources assigned to it. One physical Power6 server may be carrying several separate migration problems.
What the Power6 operating-system ceiling changes
The highest release a Power6 server can run is not the same thing as a currently supported release. IBM's map confirms the technical ceiling. IBM's lifecycle dates confirm that the ceiling is now behind the support window.
Start with the exact machine type on the Identify Your Power6 page. Then record every partition and application that must move. The migration decision is not only a hardware swap. It is an operating-system and application test plan.
