Mapping and Hosts

TheFor S1block-based systemvirtual allowsstorage containers (VSCs, also referred to as volumes), you must define initiator hosts that connect to the mappingsystem, ofand logicalmap volumes, from the same application instance,hosts to avolumes. hostThis is often referred to as LUN mapping or aLUN cluster. The mapping becomes part of a storage area network (SAN) providing a block-level storage.masking.

Hosts

To create and manage the mapping of a logical volume and to configure hosts, select Hosts .

List hosts

To display a list table of hosts, select List from the top menu.

• Name: To filter the table by the name of a host.
• Mapping: To view the logical volume mapped to each host in the list.
• IP: To view the IP assigned to each of the host in the list.
• WWN: View the World Wide Node (WWN) Fibre Channel (FCC) of the host.
• IQN: View the iSCSI Qualified Name (IQN) of the host.
• NQN: View the Network Qualified Name (NQN).
• Submit: To apply settings.

The table of hosts also supports on-the-fly filtering operations.

Creating a host

To create a host, select Create from the top menu.

• Name: Enter a name of your choice for the new host. If you are creating the same initiator on multiple systems for replication, use the same name on both systems to make it easier to pair the initiators.
• IP (optional): Enter eitherthe initiator IP address or DNS hostname. This field is not used for mapping or access. You can specify the IP address or hostname to make it easier to identify initiator hosts in the StorONE user interfaces.
• Enter an identifier for the new host using one of the following fields:
  • WWN: Enter World Wide Node (WWN) identifier for Fibre Channel (FCC) interface.
  • IQN: Enter iSCSI Qualified Name (IQN) for iSCSI interface.
  • NQN: Network Qualified Name (NQN) for Nonvolatile Memory Express (NVMe) interface.
• Submit: To create the host using the settings.

Pairing a host

HostsBlock providereplication accesssupports SPC3 persistent reservations where the locks are replicated between the nodes in a replicated system. To activate these persistent reservations, you must create an initiator host on both systems, and pair them together. This allows an initiator host that has a persistent reservation to mappedcontinue logicalwriting volumes. The access is done throughto the IPvolume orafter thea hostnamereplication oftransition the host. The host has to communicate with the relevant S1 system. Thus, to communicate with specific S1 system through host we need to pair the host with this S1 system.event.

The S1 web interface allowsIf you todo managenot multiple S1 systems. To pairdefine a host withon both systems in a specificreplicated S1system system,and selectpair Pairthem together, that host is blocked from writing to the topvolume menu.after a replication transition occurs and the secondary system becomes the primary.

• Name: To select an existing host name. Alternatively, select the Add Name icon to create a new host.
• Target System: To pair the host with a specific S1 system, selectSelect the name of the target S1 system.
• Target Host: EnterSelect the relay addressname of the S1same initiator on the target system. If it does not exist, you must first access the target system and create a host. To make it easier to match hosts, use the same name for the initiator on both StorONE systems.
• Submit: To create the pair using the settings.

Editing a host

To edit a host select, Edit from the top menu.

• Name: To select a host for editing.
• Newname: To rename the host.
• IP: To edit the hostname/IP of the host.
• WWNS: To edit the WWNS identifier.
• IQN: To edit the IQN identifier.
• NQN: to edit the NQN identifier.
• Submit: To apply settings.

Deleting a host

To delete a host, select Delete from the top menu. Use the Name field to select the name of the host and Submit to delete it.

Unpairing a host

To unpair aan initiator host fromin ana replicated S1 system, select Unpair from the top menu.

• Name: To select athe host name.
• Target System: To select athe target system.system that you want to unpair with.
• Submit: toTo unpair the host from the target system.

Mappings

The S1 storage system offers a practical solution for efficiently mapping logical volumes to block-level storage. Using host identifiers, administrators can establish connections between hosts and storage arrays. This allows for streamlined access to logical volumes, which improves storage management and resource utilization. To map a logical volume through host, select Mappings .

List mappings

To display a table list of mappings, select List from the top menu.

• Application: To filter the table by an application instance name.
• Host: To filter the table by a host name.
• Submit: To apply settings.

The table of mappings also supports on-the-fly filtering operations.

Creating and Edit a mapping

To edit or create mappings, select Edit from the top menu.

• Application: To select an application instance name.
• Host: To select a host name.
• Volume: To select existing volume from the application instance. Alternatively, you can use the Add Volume icon to create new volume in the application instance.
• Add more: To map more logical volumes to the host.
• Submit: To edit/create the mapping using the settings.
