If a pool contains DP-VOLs with deduplication enabled and a capacity saving status of Failed, you can restore the DP-VOLs by initializing the duplicated data in the pool. The Initialize Duplicated Data function initializes the status of the capacity saving function for the pool by forcibly discarding the data in DP-VOLs that have duplicated data in the pool. You can initialize the duplicated data in a pool by using CCI.
This table lists the specifications for the Initialize Duplicated Data function.
| Item | Specification |
|---|---|
| Specified range | Per pool |
| Target | DP-VOLs with a capacity saving of deduplication and compression and the deduplication system data volumes (fingerprint and data store) in the specified pool |
| Volume status after initializing duplicated data |
|
| Execution time | Initializing duplicated data takes one minute per 40 TB total capacity of the target volumes. It also takes 0.007 minutes per target volume. Execution time = 5 + ↑(Total capacity [TB]/40[TB])↑ + Number of target volumes × 0.007 minutes ↑()↑: Round up the value enclosed in ↑()↑ to the nearest whole number. For example, when the total capacity of the target volumes is 100 TB, and the number of the target volumes is 1000, the execution time is: 5 + ↑(100/40)↑ + 1000 × 0.007 = 5 + ↑2.5↑ + 7 = 5 + 3 + 7 = 15 minutes |
