volume efficiency inactive-data-compression start
Start inactive data compression on a volume.
Availability: This command is available to cluster and Vserver administrators at the advanced privilege level.
Description
The volume efficiency inactive-data-compression start command is used to start inactive data compression on a volume.
Parameters
- -vserver <vserver name>- Vserver Name (privilege: advanced)
- 
This specifies the vserver of the volume. 
- -volume <volume name>- Volume Name (privilege: advanced)
- 
This specifies the volume on which inactive data compression should be started. 
- [-s, -inactive-days <integer>]- Compression Days Count (privilege: advanced)
- 
Data older than 'inactive-days' days is compressed. 
- [-m, -scan-mode {default|compute_compression_savings|extended_recompression}]- scanner mode (privilege: advanced)
- 
This specifies in which mode inactive data compression scanner should be started. Three modes available 'default', 'compute_compression_savings' and 'extended_recompression'. 'default' scanner will start compressing the cold data in volume. 'compute_compression_savings' scanner will calculate the auto adaptive compression savings on the volume. 'extended_recompression' scanner will attempt to re-write existing cold data to reduce internal fragmentation. 
Examples
The following example displays information for starting inactive data compression scan on volume "vol1":
cluster:::> volume efficiency inactive-data-compression start -vserver vs1 -volume vol1 Inactive data compression scan started on volume vol1 in Vserver vs1.
