Verifying NTB Link (vMOS-6 Only)
The Non-Transparent Bridge (NTB) is automatically enabled during installation. If this system is
running vMOS-6, you can use the commands below to show that NTB is enabled and to show the
status of the NTB link.
To show that NTB is configured:
1. Log in to the CLI of either Memory Gateway (master or standby).
2. In enable mode, run the show ntb configured command. If NTB is configured, you
should see output similar to the following:
To show that the NTB link is up on both Memory Gateways:
1. Log in to the CLI of either Memory Gateway (master or standby).
2. In enable mode, run the show ntb status command to display the NTB link status. If the
link is up on both Memory Gateways, you should see output similar to the following:
The network interfaces are communicating if the Network status is “Up” for both Local and Remote
links.
3. If the status is not “Up” for the Local and Remote links, double-check the PCIe cable
connection between the two ACMs, making sure the cable is securely attached to both ports.
Initializing the Violin Memory Array
To configure a Violin Memory Array to support block storage, you must first initialize the Violin
Memory Array using the media init command.
1. Start a terminal application and open a connection to the Memory Gateway Master using its
management IP address or hostname, which were set up during initial configuration of the
Memory Array.
2. Log in to the Memory Gateway as “admin.”
