13.1.3.3 Error
613If you get an error 611 during boot, the problem is that the /etc/exports file either does not have the correct permissions for the client to mount /usr or does not have any entry for /usr.
To rectify this problem type the following command:
exportfs
Using the exportfs command, verify that each entry is filled in correctly.
If you receive the following error message when adding the network boot client:
Configuring network boot for client thumper.aix.dfw.ibm.com /usr/ro,root=thumper.aix.dfw.ibm.com Starting NFS and BOOTP services.. exports: /usr: sub-directory (/usr/lpp) already exported /usr not found in etc/exports
the client has been configured, but you must correct the problem with the export before booting the client.
Execute the exportfs command.
If you continue to have problems trying to export a /usr parent directory, check the /etc/exports file, and look for an existing /usr subdirectory that is not a filesystem. If you have a /usr subdirectory that is not a filesystem you will not be allowed to export /usr until you remove it from the /etc/exports/file.
An example would be:
/usr/sys/inst.images -rw /usr/lpp -root=mars,access=mars
In the above example the /usr/sys/inst.images is its own filesystem, but /usr/lpp is still part of the /usr filesystem.
Execute the following command to remove /usr/lpp from the /etc/exports file.
/usr/sbin/rmnfsexp -d /usr/lpp -B
Re-add the network boot client by running the smitty sysback command. Verify by executing the exportfs command.
