Dell PowerStore Protecting Your Data

• Use the instant access option to browse a remote snapshot before deciding whether to retrieve it, or to access a snapshot of a deleted, corrupted, or modified resource and copy it to the host.
• Only one instant access session is allowed per remote snapshot.
• An instant access session can be created for volume groups that include up to four members.
• When an instant access session is running, the PowerStore cluster does not perform backup and retrieve operations, and local resources are not protected.
• Instant access fails when a cluster reboots or fails over. To reinitiate instant access in this case, unmap the instant access volume from the host, delete the session, and then re-create the session.
• The system sets node affinity to instant access sessions at creation. If the host cannot access the node that the instant access session has affinity to, the instant access session does not failover to the other node, and the host will have problems accessing the instant access resource data.

The following information is provided on the Instant Access Sessions tab:

• Status—The session status is I/O Forwarding.
• Local Resource—Displays the new volume or volume group that is created as part of the session. Clicking the local resource hyperlink opens the Details page for this resource, where you can view the volume details or volume group members. You can also view performance data, check issued alerts, and map or unmap hosts to the resource.

From the Instant Access Sessions tab, you can end an instant access session. To end the session, you must first remove all host mappings to the local resource.

The volumes and volume groups that are created as part of instant access sessions are also displayed under Storage > Volumes > Instant Access and Storage > Volume Groups > Instant Access.
