ACM Management IP Address
The ACM management IP address is set during the initial configuration of Array Controller Module
A. This address is assigned to the master node of the cluster; if that node fails the ACM
management IP address is redirected to the standby node, which becomes the new master.
Tip: By using the ACM management IP address, you can ensure a direct and reliable connection
to the current master node for all management activities.
Monitoring the Cluster
To monitor the cluster nodes, you can use the show cluster set of commands in the CLI or the
ACM List screen in the Array Admin section of the Violin Web interface. See “CLI Reference” in the
Violin 6000 Series Memory Array User’s Guide for descriptions of the show cluster commands
and other cluster management commands.
The ACM List screen shows the ACMs that are currently part of the Memory Array cluster with their
status and role (master or standby). You can also view additional information about an ACM from
this screen. See the Violin 6000 Series Memory Array User’s Guide for information about the ACM
List screen.
The most useful of the show cluster commands is show cluster global brief. This
command can be used on any node in the cluster in Config or Enable mode (but not in Standard
mode). Command modes are explained in the Violin 6000 Series Memory Array User’s Guide.
The show cluster global brief command displays the cluster ID and name, the
management IP address and netmask, the cluster master interface, and the number of Gateways
(nodes) in the cluster. For each node, the display gives its role (master or standby), host ID, external
IP address, and internal IP address.
An asterisk after a node’s ID number designates the local node, from where you issued the
command. Below is an example of theshow cluster global brief command on the master
node:
violin-acma [violin: master] (config) # show cluster global brief
