Note:  A lack of dependent volumes does not imply that there are no volumes that use the  drive. Volume dependency actually shows the list of volumes that would become  unavailable if the drive or the group of selected drive becomes unavailable. You can get the same information with the CLI command  lsdependentvdisks . Use the  parameter  - drive  with a list of drive IDs that you are checking, separated with a colon ( : ). Select  Properties  to view more information about the drive, as shown in Figure 6-33. Action: Properties Figure 6-33 Drive properties You can find a short description of each drive property by hovering on it and clicking  [?] .

To get all available information about the particular drive, use the CLI command  lsdrive  with  drive ID as the parameter. To get slot information, see the  lsenclosureslot  command.
