Network Protocol Cautions; System Might Panic If The Network Configuration Entries In The /Etc/Rc File Are Not In The Recommended Order; Reconfiguring The Losk Interface Results In System Outage; Ipv6 Is Not Supported - IBM N Series Manual

Network protocol cautions

This information addresses network protocols cautions. Review the following
section for important information regarding network management.
For more information about these issues, see the Data ONTAP 8.0 7-Mode
Network Management Guide.
v "System might panic if the network configuration entries in the /etc/rc file
are not in the recommended order"
v "Reconfiguring the losk interface results in system outage"
v "IPv6 is not supported"
v "IPsec is not supported"
v "TOE is not supported"
System might panic if the network configuration entries in the /etc/rc file
are not in the recommended order
You should ensure that the entries in the /etc/rc file are in the recommended
order. The incorrect order can cause prolonged giveback or system reboot
time, which might result in a system panic.
For more information about the ordering of entries in the /etc/rc file, see the
Data ONTAP 8.0 7-Mode System Administration Guide.

Reconfiguring the losk interface results in system outage

If you modify the default configuration of the losk interface, it can result in a
system outage. If any IP address or routing configurations related to the losk
interface exists in the /etc/rc file, you must remove these configurations to
avoid undesirable behavior of the storage system.

IPv6 is not supported

IPv6 is not supported in Data ONTAP 8.0 and later. If you want to upgrade
from a Data ONTAP version that supports IPv6 to Data ONTAP 8.0 or later,
see the Data ONTAP 8.0 7-Mode Upgrade and Revert/Downgrade Guide.

IPsec is not supported

IPsec is not supported in Data ONTAP 8.0 and later. If IPsec is enabled on
your storage system, be aware that it will be disabled automatically during
the upgrade to the Data ONTAP 8.0 release family.

TOE is not supported

In Data ONTAP 8.0 7-Mode and later Data ONTAP 8.0.x 7-Mode releases, the
TOE functionality is not supported. There is no adverse effect on the
performance of your storage system because TOE is disabled.
