Example A-18 Updating DNS domain name
#---check the dns domainname---
n3300a> options dns.domainname
dns.domainname (value might be overwritten in takeover)
#---update
n3300a> options dns.domainname itso.tucson.ibm.com
You are changing option dns.domainname which applies to both members of the cluster in
takeover mode.
This value must be the same in both cluster members prior to any takeover or giveback,
or that next takeover/giveback may not work correctly.
Sun May 6 03:41:01 GMT [n3300a: reg.options.cf.change:warning]: Option dns.domainname
changed on one cluster node.
n3300a> options dns.domainname
dns.domainname itso.tucson.ibm.com (value might be overwritten in
takeover)
3. Check that the DNS is already enabled by running the dns info command, as shown in
Example A-19:
options dns.enable on
Example A-19 Enabling DNS
n3300a> dns info
DNS is disabled
n3300a>
n3300a>
n3300a> options dns.enable on
Sun May 6 03:50:06 GMT [n3300a: reg.options.overrideRc:warning]: Setting option
dns.enable to 'on' conflicts with /etc/rc that sets it to 'off'.
** Option dns.enable is being set to "on", but this conflicts
** with a line in /etc/rc that sets it to "off".
** Options are automatically persistent, but the line in /etc/rc
** will override this persistence, so if you want to make this change
** persistent, you will need to change (or remove) the line in /etc/rc.
