#3955 [FVT]DNS on SN doesn't work in master-slave mode on AIX hierarchy environment
Prefix :FVT
Reference :N/A
Duplicate :N/A
Component Name :DNS
Release/build :Version 2.8.4 (built Fri Dec 27 02:22:55 EST 2013)
Environment Configuration:
MN: p7hvs7br04 AIX 71H
SN: p7hvs7br15 AIX 71H
symptom :
After setting up DNS master/slave mode in AIX hierarchy environment, named on SN can't provide service due to 'named.conf' file miss DB directory option.
How to reproduce:
[root@p7hvs7br04]#chtab key=nameservers site.value="<xcatmaster>,9.114.34.67"
[root@p7hvs7br04]#chdef p7hvs7br15 setupnameserver=2
[root@p7hvs7br04]#chdef p7hvs7br15 setupdhcp=1
[root@p7hvs7br04]#makedns -n</xcatmaster>
[root@p7hvs7br04]#xdsh p7hvs7br15 "stopsrc -s xcatd"
[root@p7hvs7br04]#xdsh p7hvs7br15 "startsrc -s xcatd"
[root@p7hvs7br04]#xdsh p7hvs7br15 "lssrc -a|grep named"
named tcpip inoperative
Discussion
I found on the service node, seems AIX named can not know the default named directory, so can not load db.cache file.

I will fix it in 2.8 and 2.9.
