list The following information is displayed for the Target LDEV:
option buttons The possible values for Auto Migration Function are Enable and
Disable. If the Auto Migration function is enabled, auto migration
plans are executed automatically at the established time interval.
option buttons The Sampling Term (Date) option buttons set the frequency at which
usage statistics are analyzed. The following options are available:
drop-down lists Specify a time period for analyzing resource usage statistics by using
the From and To drop-down lists.
option buttons The Number of Sampling Points option buttons set the data that are
analyzed. The following options are available:
drop-down lists Specify the time that auto migration starts by using the drop-down
lists. If the Auto Migration function is enabled, the auto migration
operation starts at the specified time. The Migration Time should be
set at least one hour after the ending time specified in the Sampling
Term.

LDKC:CU:LDEV.
Emulation: the emulation type of the volume.
Capacity: the capacity of the volume.
RAID: the RAID type of the volume.
Protection: the data protection level.
PG: the parity group ID. If the indicated parity groups are the

usage rate during the Sampling Term to determine disk usage. Use
the list to specify the value of X.
