PRIMECLUSTER Global Link Services Configuration and Administration Guide: Multipath Function (for Solaris(TM) Operating Environment)

2.2.1.1 General notes

• When using Multipath function, if the the media listed in "Table 2.2 Supported driver version of the media" is used, the driver version shown in the table is required.
• When Solaris OS is installed, a configuration file with the name "hostname.interface_name (e.g. hostname.hme0)"for a TCP/IP interface is created in the /etc area when making the network settings, such as the configuration for the basic interface (e.g. hme0).
  When using the Multipath function, a file named "/etc/hostname.interface_name," and "/etc/hostname6.interface_name" for configuring the logical interface of the Multipath function must not be included. For example, if the hme0 interface is used in the Multipath function, the file /etc/hostname.hme0 must be deleted.
  When using the Multipath function, skip the network setup of the interface during installation of Solaris OS. If this is not possible, restart the system in single user mode after configuring the network and delete the "/etc/hostname.interface_name" and "/etc/hostname6.interface_name" file.
• The maximum number of devices (the number of communication paths) that one logical interface can use is eight. Because the main system has mounting restrictions on the number of adapters to be used, the number of devices to be installed must be checked.
  When the ATM card is used, the number of maximum devices (the number of communication paths) that one logical interface can use is two.
• The number of MPNET interfaces that can be configured is up to 16 interfaces.
• When FastEthernet is used, the "eri" driver (onboard interface) can not be used.
• When Gigabit Ethernet is used, the "vge" driver (X1044A adapter), bge driver (onboard interface) and "fjgx" driver (PW008GE2, PW008GE3 adapter) can not be used.
• When using the Jumbo Frames feature of Gigabit Ethernet, the drivers shown in "Table 2.3 Jumbo Frames supported driver" are supported. Please refer to the manual of the driver for the detail to configure Jumbo Frames support.
• When FastEthernet or Gigabit Ethernet is used, if ce driver (X2222A, X1150A, X1151A, X3150A, X3151A, X4150A, X4151A, X4422A, X4422B, X4444A, X4444B adapter) is used, one MPNET interface must be configured with ce driver only.
• FastEthernet cannot be used together with Gigabit Ethernet in one logical interface.
• When FDDI is used, only GP7B8FD2 and GP7B8FD2-F are supported with the Multipath function. Other FDDI cards are not supported.
• When ATM is used, only GP7B8AT1 and GP7B8AT1-F are supported with the Multipath function. Other ATM cards are not supported. Note that in GP7B8AT1 and GP7B8AT1-F, adapter 002AA or later can be used. Therefore, check the adapter version before installation.
• When the TCP/IP interface is used, the Multipath function will not support IPv4 tunnel and IPv6 tunnel. IPv6 is not supported, when using ATM.
• The communications that use SNMP (Simple Network Management Protocol) are not supported.
• The Multipath Function cannot use the hub.
• The Multipath Function does not support PRIMECLUSTER Scalable Internet Services (SIS).
• The Multipath Function does not support Solaris Containers (Zones). The MPNET interface can not be used as a network interface of a Non-Global Zone.

[Table 2.3 Jumbo Frames supported driver]

Driver name and version	MTU configuration file *1 *2
FUJITSU PCI Gigabit Ethernet 1.4 or later	/etc/fjmtu.fjgeX
FUJITSU PCI Gigabit Ethernet 2.0 or later	/etc/fjmtu.fjgiX
Sun GigaSwift Ethernet 1.0 or later *3	/etc/fjmtu.ceX *4

*1: To specify MTU size of the TCP/IP interface of the Multipath function, making the MTU configuration file of each physical interface used by the Multipath function is required. Write the MTU size between 1500 to 9000 in each MTU configuration file. The value in each MTU configuration file must be same. If a different value is set, the MTU size of the TCP/IP interface of the Multipath function is set to 1500. If you don't make this file, TCP/IP MTU size is set to default value (9000).
*2: X means instance number.
*3: To enable Jumbo Frames mode, use /platform/sun4u/kernel/drv/ce.conf file. Configuration of Jumbo Frames by using ndd(1M) command is not supported.
*4: When using Sun GigaSwift Ethernet 1.0 or later in Multipath function, MTU size is set with /etc/fjmtu.ceX files. Setting MTU size by using /etc/hostname.ceX (X means instance number) or ifconfig(1M) command, shown in the documents of Sun GigaSwift Ethernet 1.0 or later, can not be used.
