The Volume details pane is divided into three sections:

Connected Hosts and Host Groups

Displays a list of private host and shared host group connections to the volume, and the LUNs they use to address the volume.

Snapshots

Displays a list of volume snapshots. A volume snapshot is a point-in-time image of the contents of a volume. There are two ways to create volume snapshots: as a single volume or multiple volumes at the same time (atomically) through the Storage tab, or as part of protection group snapshots through the Protection tab.

Details

Displays additional details specific to the selected volume, including volume serial number and volume creation date.

Protection Groups

A protection group represents a collection of members (volumes, hosts, or host groups) on the FlashArray that are protected together through snapshots. The members within a protection group must be of the same storage object type, have common data protection requirements, and share the same snapshot, replication, and retention schedules.

Creating a protection group snapshot creates snapshots of the volumes within the protection group. These protection group volume snapshots, which are visible in both the Storage and Protection tabs, can then be copied to create new volumes, when necessary.

The Storage tab provides options to create new protection groups, add members (volumes, hosts, or host groups) to existing protection groups, and copy protection group volume snapshots. All other protection groups tasks are performed through the Protection tab.

Connection Map

The Connection Map displays the connectivity status between the hosts and the array controller ports.

Figure 32. Storage - Connection Map - Host Port Connectivity

Storage - Connection Map - Host Port Connectivity

The Host Port Connectivity section displays which initiator (host) ports can communicate with which array ports.

The Host column displays the Purity hosts and all of the initiator ports - as Fibre Channel Worldwide Names (WWNs) or iSCSI Qualified Names (IQNs) - that are known to the array, either through discovery or through administrator assignment.

The Paths column displays the connectivity status between the host and controllers in a highly available environment, where the colored value indicates one of the following connection health statuses:

  • Green: Fully redundant and highly available. No issues detected.

  • Yellow: Not fully redundant. Issues detected that may impact high availability.

  • Red: Single controller connectivity only.

  • Gray: No connectivity.

Possible connection statuses include:

Redundant

All paths between the host and each of the controllers in a highly available array are connected.

Uneven

The number of paths between the host and each controller is uneven. This may impact high availability. Make sure that there are the same number of paths from the host to each controller.

Unused Port

The host has unused initiators. This may impact high availability. Make sure that all of the initiators have at least one path to the array.

Single Controller

The host has paths to only one of the controllers. No paths exist to the other controller. This impacts high availability. Make sure that there are redundant paths from the host to both controllers.

Single Controller - Failover

The host has paths to one controller, but one or more of those paths has failed over.

None

The host is not connected to any of the controllers.

The port icons to the right of the Paths column show which initiator port can communicate with which array port. In the initiator port rows, the colored squares in the port icons indicate one of the following statuses:

  • Green: The path between the array port and initiator port is open and eligible for communication.

  • Yellow: The path between the array port and initiator port has failed over to the corresponding port pair on the other controller.

  • Gray: The initiator port cannot communicate with the array port.

The number of icons with green and yellow squares "total up" to the numbered icon that appears in its respective host name row.

Select the Show Hosts Only check box to hide/show the initiator port rows. Click Download CSV to download a comma-separated value text file of the host connection map details to your local machine.
