Reviewing the Lightbits Storage Cluster Connection Details
The following table lists the required details you need to use for the nvme connect command
on your application server. You can retrieve this information using the nvme connect command or an lbcli command.
Required Lightbits Storage Cluster Connection Details
| Item | Description | NVMe Connect Command Parameter | lbcli Command |
|---|---|---|---|
| Subsystem NQN | The Lightbits cluster that was used to create the volume. | -n | lbcli get cluster |
| Data NIC IP addresses | The Lightbits data NIC IP addresses for all of the cluster nodes. | -a | lbcli list nodes |
| TCP ports | The TCP ports used by the Lightbits cluster nodes. | -s | lbcli list nodes |
| ACL string | The ACL used when you created the volume on the Lightbits storage cluster. | -q | lbcli list volumes |
Obtaining the Lightbits Cluster Subsystem NQN
On any Lightbits server, enter the lbcli get cluster command.
Sample Command
$ lbcli get clusterA -J flag after lbcli indicates that the JWT is not stored in the lbcli configuration file.
Sample Output
UUID: 442a77f8-7f7a-4ab7-9fce-f1d1612e8b03currentMaxReplicas: 3subsystemNQN: nqn.2014-08.org.nvmexpress:NVMf:uuid:70492bf6-92e6-498a-872b-408ceb4d52d8supportedMaxReplicas: 3The output includes the subsystem NQN for the Lightbits cluster.
Obtaining the Lightbits Nodes Data IP Addresses and TCP Ports
On any Lightbits server, enter the lbcli list nodes command.
Sample Command
$ lbcli list nodesA -J flag after lbcli indicates that the JWT is not stored in the lbcli configuration file.
Sample Output

Obtaining the Volume ACL String
The ACL string is the ACL you used when you created the volume on the Lightbits storage cluster.
You can also review the list of existing volumes and their ACLs by executing lbcli list volumes on any of the Lightbits servers.
