Booting Process: Solaris 10 contains 5 phases of booting process, but in Solaris 9 have only 4 booting process. 1. Boot PROM phase 2. Boot Program Phase 3. Kernel Initialization Phase 4. Init Phase these phase contains both Solaris 9 & Solaris 10. but from Solaris 10 onwards added extra phase that is, 5. Svc.started Phase. I will explain in-depth what will happen in each phase. Boot PROM Phase: when you switch on the machine it will start the boot PROM phase. In this phase PROM runs the PSOT( Power on self Test). in this test it will verify's the all the Hardware attached to server. Then PROM displays the Banner with System identification Number, Model type, Processor type, Processor speed, Keyboard status, RAM information, serial number, Ethernet address, Hostid. In this Phase PROM locates the boot device by reading parameter boot-device. PROM reads the Disk vtoc on zero sector on default boo...
