Network Protocol Issues; Partner Node Might Be Unavailable During Controller Failover When An Interface Name Is Used As An Alternate Host Name In The /Etc/Hosts File; Change In Routing Configuration Maximum Value; Nis Group File Entries Should Not Exceed 1024 Characters Per Line - IBM N Series Manual

Network protocol issues

You should familiarize yourself with these network protocol issues in this
release.
For more information about these issues, see the Data ONTAP 8.0 7-Mode
Network Management Guide.

interface name is used as an alternate host name in the /etc/hosts file"
v "Change in routing configuration maximum value"
v "NIS group file entries should not exceed 1024 characters per line"
Partner node might be unavailable during controller failover when an
interface name is used as an alternate host name in the /etc/hosts file
When the interface name used for configuring the partner interface is present
in the /etc/hosts file, the IP address of the local node is substituted instead of
the IP address of the partner node. This results in the partner node being
unavailable during takeover.
To avoid this issue, you can use one of the following workarounds:
v Do not use interface names as alternate host names in the /etc/hosts file.
v Use the IP address of the partner node instead of the interface name while
configuring the partner interface.
Note: You can use the IP address of the partner node while configuring the
partner interface only when the interface belongs to the default IPspace.

Change in routing configuration maximum value

When you run the traceroute command with the -m option, you must ensure
that the maximum value of TTL does not exceed 255.

NIS group file entries should not exceed 1024 characters per line

Data ONTAP supports a maximum of 1024 characters per line in the
/etc/group file on the NIS server. NIS group file entries with more than 1024
characters can result in login denials.
To avoid login denials, you must reorganize NIS group entries such that each
line does not exceed 1024 characters.
