portmap and nfsd

UNIX AIX

Hello,

what is the relation between portmap and nfsd and how communication between them looks like. Does the nfsclient contact with the portmap or nfsd first.
Many thanks in advance for helping me to understand this :slight_smile:

Hi

As far as i know nfs and portmap are related to each other.

We recently had an issue where one of the lpar in the p7 box went down all of a sudden.

we logged a case with ibm but ibm said that there is no dump and also log is wrapped.

but they pointed us about the error entries in errpt. NFS seems to be stopping and lockd also inactive.

IBM gave the below commands to rectify :

# stopsrc -g nfs                                                       
# stopsrc -s portmap                                                   
# startsrc -s portmap                                                   
# startsrc -g nfs                                                       
# lssrc -g nfs

Thanks for your answer. I've already known this command however I wonder what is the relation between this two subsystems and what exactly portmap do?

Start by reading the man pages for both. I will give you a hint. What the portmap daemon does is in it's name :wink:
