Configuring IP addresses
During installation, you specified a range of public IP addresses to be used for physical interfaces. You also specified a range for virtual interfaces. You can see which of these addresses are assigned to each node. You can use this procedure to verify the IP addresses in your configuration. You can add additional IP addresses if you want to add additional nodes and no other IP addresses are available.
To display all the IP addresses for the cluster
- To display all of a cluster's IP addresses, enter the following:
Network> ip addr show
The output headings are:
IP
Displays the IP addresses for the cluster.
Netmask
Displays the netmask for the IP address. Netmask is used for IPv4 addresses.
Specify an IPv4 address in the format AAA.BBB.CCC.DDD, where each number ranges from 0 to 255.
Prefix
Displays the prefix used for IPv6 addresses. The value is an integer in the range 0-128.
Device
Displays the name of the Ethernet interface for the IP address.
Node
Displays the node name associated with the interface.
Type
Displays the type of the IP address: physical or virtual.
Status
Displays the status of the IP addresses:
ONLINE
ONLINE (console IP)
OFFLINE
FAULTED
A virtual IP can be in the FAULTED state if it is already being used. It can also be in the FAULTED state if the corresponding device is not working on all nodes in the cluster (for example, a disconnected cable).
To add an IP address to a cluster
- To add an IP address to a cluster, enter the following:
Network> ip addr add ipaddr netmask | prefix type [device] [nodename] [fqdns]
ipaddr | Specifies the IP address to add to the cluster. Do not use physical IP addresses to access the Access Appliance cluster. In case of failure, the IP addresses cannot move between nodes. A failure could be either a node failure, an Ethernet interface failure, or a storage failure. You can specify either an IPv4 address or an IPv6 address. |
netmask | Specifies the netmask for the IP address. Netmask is used for IPv4 addresses. |
prefix | Specifies the prefix for the IPv6 address. The accepted range is 0-128 integers. |
type | Specifies the IP address type, either virtual or physical. If type is virtual, the device is used to add new IP address on that device. If type is physical, the IP address gets assigned to given node on given device. In this case, you have to specify the nodename. |
device | Only use this option if you entered virtual for the type. |
nodename | Any node of the cluster |
fqdns | Specifies a comma-separated list of Fully Qualified Domain Name (FQDN) of the IP address. The fqdn can include the characters: a-z|A-Z|0-9 or a hyphen (-). Each level of the FQDN should be between 1 and 63 characters long and should not start or end with a hyphen (-). The last Top Level Domain (TLD) must be at least two characters and have a maximum of six characters. |
To change an IP address to online on a specified node
- To change an IP address to online on a specified node, enter the following:
Network> ip addr online ipaddr nodename
ipaddr
Specifies the IP address that needs to be brought online. You can specify either an IPv4 address or an IPv6 address.
nodename
Specifies the nodename on which the IP address needs to be brought online. If you do not want to enter a specific nodename, enter any with the IP address.
You can also modify an IP address. But note that you cannot use the ipr addr modify command to modify the IP addresses in the following scenarios:
IP is used by the NetBackup client
Replication IP
IP is used by deduplication service
IP is used by Veritas Data Deduplication server
IP is used by the NetBackup primary server
IP is used by the NetBackup media server
To modify an IP address
- To modify an IP address, enter the following:
Network> ip addr modify oldipaddr newipaddr netmask | prefix fqdns
oldipaddr
Specifies the old IP address to be modified, as either an IPv4 address or an IPv6 address. The specified oldipaddr must be assigned to the cluster.
newipaddr
Specifies the new IP address, as either an IPv4 address or an IPv6 address. The new IP address must be available.
netmask
Specifies the netmask for the new IP address. Netmask is used for IPv4 addresses.
prefix
Specifies the prefix for the IPv6 address. The value is an integer in the range 0-128.
fqdns
Specifies a comma-separated list of Fully Qualified Domain Name (FQDN) of the IP address. The fqdn can include the characters: a-z|A-Z|0-9 or a hyphen (-). Each level of the FQDN should be between 1 and 63 characters long and should not start or end with a hyphen (-). The last Top Level Domain (TLD) must be at least two characters and have a maximum of six characters.
fqdns can have NONE value. NONE is used to remove the existing FQDN entry from the
/etc/hostsfile.
To remove an IP address from the cluster
- To remove an IP address from the cluster, enter the following:
Network> ip addr del ipaddr
where ipaddr is either an IPv4 address or an IPv6 address.
