               [--cnode-ids CNODE_IDs]
               [--cnode-names CNODE_NAMEs]
               [--gw-ip IP]
               [--name NAME]
               [--vlan VLAN]

Required Parameters

--id ID

Specifies the VIP pool to modify.
Options

--ip-ranges IP_RANGES

Specifies the ranges of IPs included in the VIP pool.

Specify IP_RANGES as a list of IP ranges in the format <start IP>,<end IP>. Separate ranges with a space.

For example, --ip-ranges 10.10.10.2,10.10.10.4 10.10.10.8,10.10.10.24

--subnet-cidr CIDR

Specifies the subnet in Classless Inter-Domain Routing (CIDR) notation.

In CIDR notation, the subnet is expressed as the number of bits of each IP address that represent the subnet address. For example, the subnet mask 255.255.255.0 is expressed as 24 in CIDR notation.

Specify CIDR as an integer.

For example: --subnet 24

--cnode-ids CNODE_IDs

Dedicates a specific group of CNodes to the VIP pool. The VIPs in this pool will only be distributed among the specified CNodes.

Dedicates a specific group of CNodes to the VIP pool. The VIPs in this pool will only be distributed among the specified CNodes.

By default, VIP pools are distributed among all active CNodes.

--cnode-names CNODE_NAMEs

Dedicates a group of CNodes to the VIP pool, specifying CNodes by name. Specify CNode names as a comma separated list.

For example: --cnode-names cnode-1,cnode-3,cnode-4

By default, VIP pools are distributed among all active CNodes.

--gw-ip IP

Specifies a gateway IP. Use this option if your storage clients are on multiple subnets and you are routing your client storage traffic through a local gateway.

--name NAME

Specifies a name for the VIP Pool.

--vlan VLAN

Tags the VIP pool with a specific VLAN on the data network. See Tagging VIP Pools with VLANs.

Specify VLAN as a VLAN number (0-4096).

--vast-dns-domain-name DOMAIN_NAME

Specifies a domain name to associate with the VIP pool for DNS resolution by the VAST Cluster DNS server. If a domain suffix is defined in the DNS server configuration, it is appended to the domain name to form a FQDN.

--role PROTOCOLS|REPLICATION

Determines the usage of the VIP pool:

  • PROTOCOLS. The VIP pool is used to provide access to the cluster for data network clients.

  • REPLICATION. The VIP pool is used for native replication.

--vms-preferred

Sets CNodes participating in the VIP pool to belong to a preferred domain for VMS failover. For more details, see VMS Hosting Impact and Preferences.

--not-vms-preferred

Disables --vms-preferred.
Example

This example changes the last IP in the pool's IP range and tags the pool with VLAN 70:

vcli: admin> vippool modify --id 1 --vlan 70
