Linux
To manually connect storage to Linux-based hosts, the following steps are required:
Load Kernel Module
sudo modprobe nvme-tcpInstall nvme-cli Package
If this package is not installed, perform installation, e.g. on RHEL, CentOs and Rocky use:
sudo yum install nvme-cliTo create the connect string, run the following cmd on one of management nodes, copy-paste it and run it on your host:
sbcli lvol connect <UUID>Verify it is connected with lsblk.
ℹ️
If the lvol is of HA type, NVMe multipath will be configured automatically and the volume will be connected to three cluster nodes instead of one.

⚠️
There is a NVMe multipath bug on Amazon Linux 2, therefore, NVMe multipathing currently does not work on Amazon Linux 2.
