Open System Services NFS Management and Operations Guide

NonStop TCP/IP (Conventional and Parallel Library)
To check the NonStop TCP/IP subsystem, perform either of these actions:
• Run a TELNET session.
• Make an FTP file transfer.
If either of these programs runs, the NonStop TCP/IP subsystem is running. If the NonStop TCP/IP
subsystem is not running, see the TCP/IP configuration and management manual appropriate to
your system.
Port Mapper Process
To check the port mapper process, run the RPCINFO command.
• If the port mapper is not running, issue a TACL RUN command to start it. For information on
running the port mapper, see Chapter 4 (page 36).
• Proceed to “OSS NFS Manager Process” if the problem still exists.
OSS NFS Manager Process
To check the OSS NFS manager process, run the SCF STATUS PROCESS command.
• If the OSS NFS manager process is not running, perform a warm start of the OSS NFS
subsystem as described in Chapter 4 (page 36).
• Proceed to “LAN Interface Process” (page 75) if the problem still exists.
LAN Interface Process
To check the LAN interface process:
1. Issue an SCF STATUS LAN command.
If the LAN object is not in the STARTED state, issue an SCF START LAN command to start it.
After the LAN object is in the STARTED state, if the problem still exists, proceed to step 2.
2. Issue an SCF STATS LAN command to examine the LAN interface process statistics.
If the LAN interface process has logged any I/O errors, check whether the OSS NFS manager
process is running. If the OSS NFS manager process is not running, issue a TACL RUN
command to start it. For information on running the OSS NFS manager process, see Chapter 4
(page 36).
3. If the problem still exists, proceed to “OSS NFS Server” to check the OSS NFS servers.
OSS NFS Server
To check an OSS NFS server:
1. Issue an SCF STATUS SERVER command.
If the server is not in the STARTED state, issue an SCF START SERVER command to start it.
After the server is in the STARTED state, if the problem still exists, proceed to step 2.
2. Issue an SCF STATS SERVER command to examine the server statistics.
If the server has logged any I/O errors, check the DP2 process as described in “DP2”
(page 76).
3. Issue an SCF STATUS APPL $ZQnn.* command to ensure that the QIO subsystem is started
and the OSS NFS server is a registered application.
OSS Monitor and OSS Name Server
To check the OSS Monitor and OSS name server process:
