Hi I set up the nfs clients to multiply servers, all are working except this one. 

lssrc -g nfs
Subsystem         Group            PID          Status
 biod             nfs              6160404      active
 nfsd             nfs                           inoperative
 rpc.statd        nfs                           inoperative
 rpc.lockd        nfs                           inoperative
 rpc.mountd       nfs                           inoperative
 nfsrgyd          nfs                           inoperative
 gssd             nfs                           inoperative

I try to do   startsrc -g nfs

Multiple instances are not supported.
0513-059 The nfsd Subsystem has been started. Subsystem PID is 6553784.
0513-059 The rpc.statd Subsystem has been started. Subsystem PID is 6553786.
0513-059 The rpc.lockd Subsystem has been started. Subsystem PID is 6684782.
0513-059 The rpc.mountd Subsystem has been started. Subsystem PID is 6684784.
0513-059 The nfsrgyd Subsystem has been started. Subsystem PID is 6684786.
0513-059 The gssd Subsystem has been started. Subsystem PID is 6684788

and all still on the inoperative

 nfsd             nfs                           inoperative
 rpc.statd        nfs                           inoperative
 rpc.lockd        nfs                           inoperative
 rpc.mountd       nfs                           inoperative
 nfsrgyd          nfs                           inoperative
 gssd             nfs                           inoperative

when I test the binary, 

ls -ld /usr/sbin/nfsd
-r-xr-xr-x    1 root     system        13542 Oct 20 2017  /usr/sbin/nfsd
[2023/12/14 22:39:35 ] [root@FIWQHSIVMP022V:/root$
/usr/sbin/nfsd
nfsd: No such file or directory

ls -ld /usr/sbin/rpc.lockd
-r-xr-xr-x    1 root     system         7356 Oct 20 2017  /usr/sbin/rpc.lockd
[2023/12/14 22:40:50 ] [root@FIWQHSIVMP022V:/root$
/usr/sbin/rpc.lockd
rpc.lockd: No such file or directory

The binary seems not know in the OS.  I have no idea what is the issue for that.

lslpp -l |grep nfs
  bos.net.nfs.client        7.1.5.15  COMMITTED  Network File System Client
  bos.net.nfs.client        7.1.5.15  COMMITTED  Network File System Client

Any suggestions?

/usr/sbin/rpc.lockd is part of bos.net.nfs.client, if the lpp is installed but the file is missing, you have a corrupted installation.

Would this be the same system where you had mkcd fail due do a missing /usr/bin/sed ?

Any relation to the iSCSI storage you've mentioned before ?

it is not the same system I talked about. 

the actually files are there

ls -ld /usr/sbin/rpc.lockd
-r-xr-xr-x    1 root     system         7356 Oct 20 2017  /usr/sbin/rpc.lockd

file /usr/sbin/rpc.lockd
/usr/sbin/rpc.lockd: executable (RISC System/6000) or object module

# file /usr/sbin/rpc.lockd
/usr/sbin/rpc.lockd: executable (RISC System/6000) or object module

it getting the error if run it

/usr/sbin/rpc.lockd
ksh: syntax error: `(' unexpected

after I play around

Can you verify all the files of the fileset, bos.net.nfs.client on your system using lppchk?

You can use below commands

lppchk -c bos.net.nfs.client

lppchk -f bos.net.nfs.client

Wang,

do I understand your output correctly? You have the binary on the system and it looks good, but you can't execute the command:

ls -ld /usr/sbin/rpc.lockd
-r-xr-xr-x    1 root     system         7356 Oct 20 2017  /usr/sbin/rpc.lockd
[2023/12/14 22:40:50 ] [root@FIWQHSIVMP022V:/root$
/usr/sbin/rpc.lockd
rpc.lockd: No such file or directory

I know such behaviour if some security tools are installed preventing execution of "non-secure binaries". You can search through logs if they're configured and you usually see there some error message.

Can you verify if an nfsd process is already running in your system?

ps -eaf | grep nfsd

If an instance of nfsd is already running, you will face this kind of error.
