"disk" | Disk statistics for all partitions. Options include:
|
"buffer" | Buffer statistics for all drives. Options include:
|
"all" | All usage statistics for the Cache Engine. |

The message "value = 0 = 0x0" displays to indicate that the command display is complete.
See the Table 4-4 through Table 4-6 in "Optimizing the Cache Engine" for a description of the statistical terms.
The DirectoryDump command displays the drive's partition contents on your console. Each Cache Engine contains 15 partitions [numbered from zero (0) to fourteen (14)].
| Variable | Description |
|---|---|
"partition" | Contents of an individual partition number 0 through 14. For example, DirectoryDump "1" |
"all" | Contents of all partitions |
 | Caution Issuing the DirectoryDump command with the "all" parameter is very time-consuming. A fully populated Cache Engine may contain up to 24 GB of data. The "all" parameter will display (and occupy) your console until all data has been dumped. The only way to stop the data dump is to reboot your Cache Engine. |
See the "Updating the Basic Configuration" section in "Managing the Cache Engine," for console rebooting instructions.
