chunklets back to their original positions on the drive magazine and to reconstruct the
chunklets on the new disk.
Once
servicemag resume is issued, chunklets in the logging state enter the playback
state as their data is played back. Once all data is played back, the chunklets return to the
normal state. Any chunklets in the normal,smg state return directly to the normal state.
To confirm that the operation relocating chunklets to their original positions and
reconstructing them on the new disk has completed, issue the
servicemag status
command, specifying the drive cage number and position of the drive magazine.
Chunklet states can be checked by issuing either
showldch or showpdch commands.

■ Chunklets of invalid RAID sets cannot be relocated.
■ Depending on the number of chunklets relocated, this process can take several hours to
