Multi VLAN operations are supported with the iSCSI virtual port mode, which enables you to add up to 16 virtual ports to a single physical iSCSI port. Virtual ports are used to access the storage system using multiple segments that are divided by VLAN, enabling efficient use of ports and network resources.
You can perform the following multi VLAN operations using Command Control Interface.
- Enabling and disabling the iSCSI virtual port mode
- Adding and deleting virtual ports
The following restrictions apply when using the iSCSI virtual port mode:
- The iSNS function cannot be used when the iSCSI virtual port mode is enabled.
- If the iSCSI virtual port mode is enabled, the port information when the virtual port mode is disabled is taken over to the iSCSI virtual port ID (0). If iSCSI port IDs from 1 to 15 are added, specify IPv4 or IPv6.
- If an IPv6 address is used on a virtual port, multiple virtual ports cannot be used in the same network.
- If multiple IPv6 virtual ports are created on the same physical port, assign a different VLAN ID for each IPv6 virtual port.
- Do not disable VLANs for multiple IPv6 virtual ports. Disabling a VLAN for an IPv6 virtual port sets the VLAN ID to 0. Therefore, disabling VLANs for multiple IPv6 virtual ports causes duplicate VLAN IDs on the same physical port.
- When the setting for the virtual port mode is changed, Link Down/Link Up (temporary disconnecting) occurs on the target iSCSI port. Change the mode only when the I/O loads are low.
