Member State Description 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 firmware. 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. Resume Compression To resume compression on a member after it has been suspended: 1. Click Group. 2. Expand Members and select the group member on which compression is to be resumed. 3. In the Activities panel, click Resume compression. The General Member Information panel shows Compression ... running under the General settings section, and the Activities panel again contains the Suspend compression link. 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. View Compression Statistics by Pool You can view the compression statistics of an entire storage pool containing compression-capable members. 1. Click Group. PS Series Group Operations 139
