Explanation of SeLinux  interaction with following components

Snapshot replication

Our Snapshot Replication service is uses secure ssh based interaction communication between MayaNAS servers that uses with proper selinux context ssh_t secontext t  as required.  Usually no impact form selinux.

Viewing or Assign Initiator or Target mode of operation for FC controllers

Configure iSCSI

This configuration is for creating your own iSCSI target names and portal addresses. It is useful when you have multiple network interfaces and would like to control iSCSI service over particular subnet or network controller preference.

Portal Groups

MayaNAS server will create a default Portal Groups contain list of IPv4 addresses associated with a tag number for referencing.  When iSCSI volume is associated with this tag the iSCSI discovery addresses are returned only with the addresses specified in that portal group.

1. Enter Portal Tag a value of 1 .. 255
2. Enter the first IP Address of that list
3. Enter additional IP Address if available

iSCSI Target Names

MayaNAS server by default creates  iSCSI target name based on system hostname and hostid, while provisioning iSCSI volume to hosts.  But you can may wish to create additional iSCSI target names and iSCSI portals to control the iSCSI service over particular subnet or network controller preference.

1. The Node name is the standard iSCSI name, which is similar to DNS naming convention.  No underscore is permitted in the name.
2. The Portal Tag is the number referencing the IP address portal list
3. CHAP User is the user name for iSCSI initiator to use for authentication.
4. CHAP Password is the password for iSCSI initiator to use for authentication.
5. Click Apply to save.

Configure NVMET

This configuration is for creating your own NVMe subsystem name and transport addresses. This way you  have the flexibility of creating multiple controller names  in addition to multiple namespaces in a single controller.

Portal Groups

Portal Groups contain list of IPv4 addresses associated with a tag number for referencing.  The transport address and port number is used by the NVMe fabrics discovery from the host side.

1. Enter Portal Tag a value of 1 .. 255
2. Enter the first IP Address for discovery from NVMe host.  This field should contain valid IPv4 address even for Infiniband RDMA discovery.
3. Enter Port Number  also known as service ID for NVMe discovery.

NVMe Target Names

These are NVMeoF subsytem name similar to iSCSI naming convention except they start with nqn.

1. The Node name is the standard NVMeoF subsystem name which is similar to DNS naming convention.  No underscore is permitted in the name.
2. The Portal Tag is the number referencing the transport address portal information.
3. Click Apply to save.
