Nutanix volumes with Linux

How to Configure Linux Clients for Connectivity

1. Install the iSCSI initiator package on RPM distro.
   a. sudo yum install iscsi-initiator-utils
2. Check to ensure that the iSCSI daemon is running on the host.
   a. RHEL 6: sudo /etc/init.d/iscsi status
   b. RHEL 7: sudo service iscsid status
   c. Replace status with start if the status is not returned as running.
3. Get the iSCSI initiator name from the host.
   a. cat /etc/iscsi/initiatorname.iscsi
4. Create a Nutanix VG using acli.
   a. Connect to any CVM using SSH.
   b. Run the aCLI .
5. Create a VG.
   a. vg.create vg_name
   b. Example: vg.create DATADG shared=true
   c. Specify shared if the disks are shared across hosts.
6. Add one or more disks to the VG.
   a. vg.disk_create DATADG container=container_name create_size=disk_size
   b. Example: vg.disk_create DATADG container=DATABSE create_size=500G
7. Attach the initiator IQN to the VG. Do this for each host participating in the cluster.
   a. vg.attach_external vg_name initiator_name=initiator_iqn
   b. Example: vg.attach_external DATADG initiator_name=iqn.1994-05.com.redhat:oracerac
8. Discover the available targets on the host.
   a. iscsiadm -m discovery -t st -p , where -p is the
   iSCSI data services IP address.
   b. Take note of the listed targets.
9. Connect to the discovered targets on the host.

a. iscsiadm -m node –login

10. Verify that the disk is attached.
    a) rescan host bus adaptor

b) run lslk to see the disk
