Table 32. Member Compression States
Member State Description
No-Capable-Hardware Compression cannot be enabled on this member due to its hardware capabilities.
Not Started Compression has never been successfully enabled on this member.
Running Compression is currently running on this member.
Suspended Compression has previously been enabled and is now paused.
Unknown The compression state of the member cannot be determined due to the member being
oine or an internal error condition.
NOTE: This status is visible only within the pool area.
Enable Compression
Snapshot and replica compression can be enabled on any PS6210 or PS6610 array running the supported rmware. Compression is
enabled at the pool level. If the group contains more than one compression-enabled member, compression must be enabled on each
member individually.
1. Click Group.
2. Expand Members and select the group member on which compression is to be enabled.
3. In the Activities panel, click Start compression.
The Compression Settings dialog box opens and reminds that compression cannot be undone but only suspended after it is
enabled.
4. Click the Continue button.
The General Member Information panel shows Compression ... running under the General settings section, and the
Activities panel contains a
Suspend compression link, which is used to temporarily pause compression.
NOTE: When compression is initially enabled or resumed after being suspended, the display for compression statistics
might not change for several hours as the array monitors activity.
Suspend Compression
Snapshot and replica compression can be temporarily suspended on a member to immediately stop the compression of new
snapshots. This process does not rehydrate already compressed data; all compressed data remains in its compressed state when
compression is suspended.
1. Click Group.
2. Expand Members and select the group member on which compression is to be suspended.
3. In the Activities panel, click Suspend compression.
The General Member Information panel shows Compression ... suspended under the General settings section, and the
Activities panel contains a
Resume compression link, which is used to reactivate compression.
NOTE: When compression is initially enabled or resumed after being suspended, the compression statistics might not
change for several hours as the array monitors activity.
