Enabling accelerated compression
Before you begin
You must have the Storage Administrator role.
Set the parity group drive type to FMC.
The emulation type of the target parity group must be OPEN-V.
The RAID level and drive configuration of the target parity group must be accessible for use for pool volumes.
The target parity group must be in a storage system (an internal parity group, block, or file). Parity groups for the embedded NAS module are supported.
The status of LDEVs in the target parity group must be Normal or Blocked.
The capacity of the defined internal volumes must be 8 GB or more. (The capacity is equal to or greater than the minimum capacity of a pool volume.)
If the defined internal volumes are used as pool volumes, those pool volumes belong to the same Dynamic Provisioning pool or Thin Image pool.
The defined internal volumes must have no LUN path definitions.
The defined internal volumes must not be used by Volume Migration.
The defined internal volumes must not be reserved by the Data Retention Utility.
The defined internal volumes must not have the Protect, Read Only, or S-VOL Disable attribute of Data Retention Utility.
The encryption setting of the parity group must be disabled.
There must not be any DP-VOL page reserved areas.
Procedure
Perform one of the following to display the parity group to be operated.
In Hitachi Command Suite:
On the Resources tab, click Storage Systems, and then expand All Storage Systems and the target storage system.
Click Parity Groups of the target storage system.
In Device Manager - Storage Navigator:
Perform one of the following to display the Parity Groups tab:
To display all parity groups in the storage system, in the storage system tree, select Parity Groups, then select the Parity Groups tab.
To display parity groups related to Internal, in the storage system tree, expand Parity Groups, select Internal, then select the Parity Groups tab.
After displaying the parity group, select the target parity group.
Open the Edit Parity Groups window.
In Hitachi Command Suite:
On the Resources tab, click Storage Systems, and then expand All Storage Systems and the target storage system.
Click Parity Groups.
Select one or more parity groups, and then click Edit Parity Groups.
In Device Manager - Storage Navigator:
Click Storage Systems, and then expand the Storage Systems tree.
Click Parity Groups.
On the Parity Groups tab, select a parity group.
Click More Actions > Edit Parity Groups.
In Accelerated Compression, check Enable.
When you enable accelerated compression, confirm if the data reduction efficiency can be achieved. For details, see Guidelines for pools when accelerated compression is enabled.
Click Finish.
In the Confirm window, confirm the settings. In Task Name, type a unique name for this task or accept the default, then click Apply. If Go to tasks window for status is checked, the Tasks window opens.
