Adds a virtual IP address.

Permissions Required

fc or a on the cluster.

Syntax

maprcli virtualip add
    [ -cluster <cluster> ]
    [ -gateway <gateway> ]
    [ -macs <MAC address> ]
    -netmask <netmask>
    -virtualip <virtualip>
    [ -virtualipend <virtual IP range end> ]
    [ -preferredmac <MAC address> ]

Parameters

Parameter Description
cluster The cluster on which to run the command.
gateway The NFS gateway IP or address
macs A list of the MAC addresses that represent the NICs on the nodes that the VIPs in the VIP range can be associated with. Use this list to limit VIP assignment to NICs on a particular subnet when your NFS server is part of multiple subnets.
netmask The netmask of the virtual IP.
preferredmac The preferred MAC for this virtual IP. When an NFS server restarts, the MapR system attempts to move all of the virtual IP addresses that list a MAC address on this node as a preferred MAC to this node. If the new value is null, this parameter resets the preferred MAC value.
service The service to assign VIPs to. Value can be one of the following:
  • nfs3 — for NFSv3
  • nfs4 — for NFSv4
The default value is nfs3, which is used if this option is not specified. You must specify the MAC addresses (macs) with this option.
virtualip The virtual IP, or the start of the virtual IP range.
virtualipend The end of the virtual IP range.
