Display the current node list and the current list of IP Networking Multipathing groups that are configured for each resource in the resource group.
# scrgadm -pvv -g resource-group | grep -i nodelist # scrgadm -pvv -g resource-group | grep -i netiflist |
The output of the command line for nodelist and netiflist identifies the nodes by node name. To identify node IDs, run the command scconf -pv | grep -i node-id.
Update netiflist for the network resources that the node addition affects.
This step overwrites the previous value of netiflist, and therefore you must include all of the IP Networking Multipathing groups here.
# scrgadm -c -j network-resource -x netiflist=netiflist |
Changes a network resource.
Specifies the name of the network resource (logical hostname or shared address) that is being hosted on the netiflist entries.
Specifies a comma-separated list that identifies the IP Networking Multipathing groups that are on each node. Each element in netiflist must be in the form of netif@node. netif can be given as an IP Networking Multipathing group name, such as sc_ipmp0. The node can be identified by the node name or node ID, such as sc_ipmp0@1 or sc_ipmp@phys-schost-1.
If the HAStorage or HAStoragePlus AffinityOn extension property equals True, add the node to the appropriate disk set or device group.
If you are using Solstice DiskSuite or Solaris Volume Manager, use the metaset command.
# metaset -s disk-set-name -a -h node-name |
Specifies the name of the disk set on which the metaset command is to work
Adds a drive or host to the specified disk set
Specifies the node to be added to the disk set
SPARC: If you are using VERITAS Volume Manager, use the scsetup utility.
On any active cluster member, start the scsetup utility.
# scsetup |
The Main Menu is displayed.
On the Main Menu, type the number that corresponds to the option for device groups and volumes.
On the Device Groups menu, type the number that corresponds to the option for adding a node to a VxVM device group.
Respond to the prompts to add the node to the VxVM device group.
Update the node list to include all of the nodes that can now master this resource group.
This step overwrites the previous value of nodelist, and therefore you must include all of the nodes that can master the resource group here.
# scrgadm -c -g resource-group -h nodelist |
Changes a resource group
Specifies the name of the resource group to which the node is being added
Specifies a comma-separated list of the names of the nodes that can master the resource group
Verify the updated information.
# scrgadm -pvv -g resource-group | grep -i nodelist # scrgadm -pvv -g resource-group | grep -i netiflist |
This example shows how to add a node (phys-schost-2) to a resource group (resource-group-1) that contains a logical hostname resource (schost-2).
