An administrator is upgrading 5 partitions on a single system to a new IBM i release.
The IBM i partitions share a tape library configured with one drive per partition. There is one DVD
drive on the system shared by the all the partitions.
The maintenance window is long enough to upgrade at most one partition using DVD media.
Which approach allows the administrator to complete all the upgrades within the maintenance
window?

A.
Build an image catalog with the distribution media, and copy to all partitions.
Install each partition from its image catalog image.

B.
Build an image catalog on a Linux PC, and share it with NES to all partitions.
Concurrently update all the partitions using network install to the virtualized image catalog.

C.
Build an image catalog with the distribution media on one partition.
Save the directory with the DVD images to tapes so there is one tape for each partition. Use an
alternate IPL device to install from the tapes.

D.
Concurrently IPL all partitions in “D” mode to the DVD drive in shared mode.
When all the partitions complete using one DVD and prompt for the next one, insert the next DVD
in the drive and respond to the prompts.
