The correct answer is A. Select a boot device. When an LPAR profile is recreated on the HMC from scratch, the boot device list is empty, so the administrator must manually select a boot device from SMS before the OS can load from the VIO Server-mapped disk.
Question
An existing client LPAR has been manually moved from one physical machine to another. The administrator updated the SAN zoning to deallocate from the source VIO Server and allocate to the destination VIO Server. The LPAR and its profile were recreated on the HMC and the single disk is mapped from the VIO Server to the LPAR. What manual intervention is required after activating the LPAR?
Options
- ASelect a boot device.
- BCorrect the system clock.
- CCorrect the terminal type.
- DImport non-root volume groups

Why each option
When an LPAR profile is recreated on the HMC from scratch, the boot device list is empty, so the administrator must manually select a boot device from SMS before the OS can load from the VIO Server-mapped disk.
A recreated LPAR profile on the HMC does not retain the original boot device list, so upon first activation the LPAR enters SMS (System Management Services) and halts waiting for a boot device selection. The administrator must navigate SMS to select the VIO Server-mapped virtual disk as the boot device before AIX can be loaded. This is a required and expected manual step any time an LPAR profile is built from scratch on a new HMC without importing the original profile data.
While the system clock may drift during a physical migration, AIX synchronizes time via NTP automatically on boot and manual clock correction is not a prerequisite to activating and booting the LPAR.
The terminal type for the HMC virtual terminal session is determined by the HMC client and does not require any manual correction as part of the LPAR activation process.
Importing non-root volume groups is an AIX-level varyon operation performed after the OS has fully booted; it cannot be the first required manual step because the system cannot reach the OS prompt until a boot device is first selected.
