On the Storage System (RDR400X)

In this example, we need to create a user profile on the Storage System with the same UID as the instance profile on the Archive System. Objects created on the Storage System will be owned by this user profile. On the Archive System, QUSROND has a UID of 588. You can use the Create User Profile (CRTUSRPRF) command as shown to create the companion user profile on the Storage System. Note that we specify the same language parameters as used on the Archive System.

CRTUSRPRF USRPRF(YQUSROND) USRCLS(*PGMR) INLPGM(*NONE) INLMNU(*SIGNOFF) 
     LMTCPB(*NO) TEXT('ONDEMAND NFS MOUNT PROFILE') SPCAUT(*IOSYSCFG 
     *JOBCTL *SAVSYS) GRPPRF(QRDARS400) LANGID(ENU) CNTRYID(US) CCSID(37) 
     CHRIDCTL(*JOBCCSID) SETJOBATR(*CCSID *DATFMT *DATSEP *DECFMT *SRTSEQ *TIMSEP) 
     LOCALE('/QSYS.LIB/EN_US.LOCALE') UID(588)

If the needed UID is already in use, see Special consideration for UIDs for information on changing the UID of an existing user profile.

We then create the following directories and subdirectories in IFS on the Storage System for use with NFS:

/NFSSTG/YQUSROND/PRIMARY

/NFSSTG/YQUSROND/BACKUP

To automatically export the file systems when the NFS server is started, update the /etc/EXPORTS file in IFS on the Storage System (which is ABC in our example).

The /etc/EXPORTS file for our example would look like the following:

/NFSSTG/YQUSROND/PRIMARY root=ABC.EXAMPLE.COM, \
                       access=ABC.EXAMPLE.COM, \
                           rw=ABC.EXAMPLE.COM \
   #HOSTOPT HostName=ABC.EXAMPLE.COM, \
            NoWaitForWrites
/NFSSTG/YQUSROND/BACKUP root=ABC.EXAMPLE.COM, \
                      access=ABC.EXAMPLE.COM, \
                          rw=ABC.EXAMPLE.COM \
   #HOSTOPT HostName=ABC.EXAMPLE.COM, \
            NoWaitForWrites

Start the NFS servers using the Start NFS Server command:

STRNFSSVR SERVER(*ALL)

The job log contains these messages:

Start of NFS server daemon or daemons of type *RPC was successful.
Start of NFS server daemon or daemons of type *BIO was successful.
2 entries exported, 0 entries not exported.
Start of NFS server daemon or daemons of type *SVR was successful.
Start of NFS server daemon or daemons of type *MNT was successful.
Start of NFS server daemon or daemons of type *NSM was successful.
Start of NFS server daemon or daemons of type *NLM was successful.
Start NFS server command completed successfully.

Notes:

The user starting NFS servers must have input/output (I/O) system configuration (*IOSYSCFG) special authority to use this command.
The user starting NFS servers must be enrolled in the system distribution directory. Use the Add Directory Entry (ADDDIRE) command to enroll the user.

To determine if an NFS server is running, use the Work with Active Jobs (WRKACTJOB) command and look in the subsystem QSYSWRK for existence of the following jobs:

QNFSRPCD - the RPCBind daemon
QNFSBIOD - the block I/O (BIO) daemon
QNFSNFSD - the NFS server (SVR) daemon
QNFSMNTD - the mount (MNT) daemon
QNFSNSMD - the network status monitor (NSM) daemon
QNFSNLMD - the network lock manager (NLM) daemon

If necessary, you can manually export or unexport the directories. To export all entries in /etc/EXPORTS:

EXPORTFS OPTIONS('-A')

To unexport all entries in /etc/EXPORTS:

EXPORTFS OPTIONS('-A -U')
