<p>The Start Network File System Server (STRNFSSVR) command starts one or all of the following Network File System (NFS) server daemons. For more information about these daemon jobs, see Network File System book, SC41-5714
|
||
|
|
</p>
|
||
|
|
<p>SERVER(*ALL) should be used, which will start the daemons in the following order. (This order is the recommended order for starting the Network File System daemons.)
|
||
|
|
</p>
|
||
|
|
<ul>
|
||
|
|
<li>The Remote Procedure Call (RPC) RPCBind daemon
|
||
|
|
</li>
|
||
|
|
<li>The block input/output (I/O) (BIO) daemon
|
||
|
|
</li>
|
||
|
|
<li>The server (SVR) daemon
|
||
|
|
</li>
|
||
|
|
<li>The mount (MNT) daemon
|
||
|
|
</li>
|
||
|
|
<li>The network status monitor (NSM) daemon
|
||
|
|
</li>
|
||
|
|
<li>The network lock manager (NLM) daemon
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p>If just one daemon is to be started, be sure the appropriate order for starting NFS daemons and the possible consequences of starting daemons in an order other than that specified above are understood. For more information about starting NFS daemons, see Network File System book, SC41-5714
|
||
|
|
</p>
|
||
|
|
<p>If the user attempts to start a daemon or daemons that are already running, they will not cause the command to fail, and it will continue to start other daemons that were requested to start. The command will issue diagnostic message CPDA1BA or CPDA1BD if the daemon is already running. However, for best results, end NFS daemons before attempting the STRNFSSVR command.
|
||
|
|
</p>
|
||
|
|
<p>To determine if an NFS daemon is running, use the Work with Active Jobs (WRKACTJOB) command and look in the subsystem QSYSWRK for existence of the following jobs:
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
<pre>
|
||
|
|
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
