This section explains how to modify network resource settings.
The following items can be modified.
Operation | L-Server Status | ||||||
|---|---|---|---|---|---|---|---|
Physical L-Server | Physical L-Server (iSCSI Boot) | Virtual L-Server | |||||
Defined | Preserved | Allocated | All | Defined | Preserved | Allocated | |
IP address change (Admin LAN/public LAN) (*1) | Yes | Yes | Yes | Yes | Yes (*2) | - | - |
Changing network resources to connect to a NIC or a NIC group | Yes | Yes | Yes | - | Yes (*2) | - | - |
NIC addition and deletion | Yes | - | - | - | Yes (*2, *4) | Yes (*5) | Yes (*5) |
Changing untagged VLAN settings (use/not use) | Yes | Yes | Yes | - | - | - | - |
Adding or deleting network resources to connect to a NIC or a NIC group | Yes | Yes | Yes | - | - | - | - |
Redundancy modification (Example: Changing the combination of NIC1 and 2 to NIC3 and 4) | Yes | Yes (*3) | Yes (*3) | - | - | - | - |
Redundancy addition (Example: Changing NIC1 to the combination of NIC1 and 2) | Yes | Yes (*3) | Yes (*3) | - | - | - | - |
Redundancy deletion (Example: Changing the combination of NIC1 and 2 to NIC1 only) | Yes | Yes (*3) | Yes (*3) | - | - | - | - |
*1: Changing IP addresses across subnets is not possible.
*2: IP addresses and network resources of virtual L-Servers can only be changed when the server's status is "defined".
*3: Select "Admin LAN (MAC address 1)" of the physical server that the L-Server will be located on, as the admin LAN of the physical L-Server. When performing admin LAN redundancy for the physical L-Server, all NICs of the admin LAN for the physical server that the L-Server will be located on must be included.
*4: For L-Servers with RHEL-KVM or RHEL-Xen selected for the VM type, the NIC cannot be added or deleted.
*5: For L-Servers with VMware, Hyper-V, Solaris Containers, or RHEL-KVM selected for the VM type, NICs can be added or deleted.
Note
Modifications to L-Server specifications have no effect on the settings of the OS installed on the L-Server. Modify the network settings of the OS referring to the IP address and network information of the modified L-Server.
For physical L-Servers, the position of the NIC used for the admin LAN cannot be changed.
After deployment of L-Servers, do not change the labels for network resources using port groups on VMware.
When the label for a network resource to use is changed accidentally, the new L-Server deployment will fail.
Use the following procedure to change network settings.
When the L-Server status is "defined"
Right-click the target L-Server in the orchestration tree, and select [Change Settings]-[Definition] from the popup menu.
The [Modify L-Server's definition] dialog is displayed.
Use the [Network] tab to change network resource settings of the L-Server.
Information
For Physical L-Servers
For details on operation of the [Network] tab, refer to "16.2.4 [Network] Tab".
For Virtual L-Servers
For details on operation of the [Network] tab, refer to "16.3.4 [Network] Tab".
Click <OK>.
When resources have not been allocated (preserved) or have been allocated (allocated) to the L-Server
Note
When resources have not been allocated (preserved) or have been allocated (allocated) to the L-Server, only the network resources of physical L-Servers can be modified.
Right-click the target L-Server in the orchestration tree, and select [Change Settings]-[Network Configuration] from the popup menu.
The [Change network configuration of an L-Server] dialog is displayed.
Enter the following items:
Clicking <Add> adds a network.
Select a network resource to connect with in the [Add a Network] dialog.
Information
- When adding a new NIC or NIC group, select the number of "(Undefined)" for [NIC] in the [Add a Network] dialog. When performing redundancy for the NIC, select the pair of NICs to use.
- When adding an already defined NIC or a network to connect with the NIC group, select the number of defined NICs for [NIC] in the [Add a Network] dialog.
Clicking <Delete> deletes the selected network.
If the number is not the NIC number specified when creating an L-Server, <OK> is not activated. When <OK> is not activated, click <Add> to configure undefined NICs.
Click <Change> to select a network resource that is connected to a NIC or a NIC group.
Enter an IP address to set for the L-Server. If the IP address is not entered, an IP address is automatically allocated to the L-Server.
Select whether or not to use untagged VLAN for a NIC or a NIC group.
Click <OK>.
From the command-line, execute rcxadm lserver modify.
For details on the rcxadm lserver modify command, refer to "3.6 rcxadm lserver" in the "Reference Guide (Command/XML) CE".
Use the rcxadm lserver attach and detach commands for adding and deleting NICs.
For details on the rcxadm lserver attach command, refer to "3.6 rcxadm lserver" in the "Reference Guide (Command/XML) CE".
