Hi, I'm useing AIX v5.3 and I want to adjust the no parameters by appending relavent commands in the /etc/rc.net file, but it did not work, and I found the reason is what the comments in the /etc/rc.net file claming:

##################################################################

1. NOTE: The no option enable/disable in rc.net only works on pre
2. 5.2 systems.
3. On systems 5.2 or higher in order to enable/disable
4. specific no options on future reboots this information has
5. to be present in the /etc/tunables/nextboot file. This can
6. be done by using no -r -o <no_optionname>=<value> on the command
7. line. On subsequent reboots the the specified no_optionname value
8. will be maintained since it will be written to the nextboot file
9. To summarize a no option can be set as follows to be enabled
10. on future reboots
11. Pre 5.2 Systems:
12. no -o arptab_size=10
13. 5.2 and later:
14. use no -r -o arptab_size=10; this creates an entry in the
15. nextboot file and preserves the value on subsequent reboots

##################################################################

but I'm still wondering how it functions: after AIX v5.2, during the 2nd boot phrase, when the command cfgmgr loads the file /etc/rc.net , reads line by line, performs appropriate actions, it just ignore any no command in this file, right?

any clue would be appreciated :)

Don't think they are ignored but they are "fixed" later. man tunrestore.

1. lsitab -a|egrep '^brc|^tunables'

brc::sysinit:/sbin/rc.boot 3 >/dev/console 2>&1 # Phase 3 of system boot
tunables:23456789:wait:/usr/sbin/tunrestore -R > /dev/console 2>&1 # Set tunables
