AUTOMOUNT=1
AUTO_MASTER="/etc/auto_master"
AUTO_OPTIONS="-f $AUTO_MASTER"
Installation Step: IS810
Make sure that at least one NFS client daemon and one NFS server daemon is configured to run .
This is required for the automounter to work. Check the listed variables in
/etc/rc.config.d/nfsconf. They should be specified as greater or equal to one.
Example:
NFS_CLIENT=1
NFS_SERVER=1
NUM_NFSD=4
NUM_NFSIOD=4
Installation Step: IS820
Add the following line to your /etc/auto_master file :
/- /etc/auto.direct
Installation Step: IS830
Create a file called /etc/auto.direct.
Identify the HA file systems as named in chapter Planning the Storage Layout and tables referring
to the used database for each directory configured to be mounted below /export. For each HA
file system add a line to /etc/auto.direct.
Example:
/usr/sap/trans <relocdbci_s>:/export/usr/sap/trans
/sapmnt/<SID> <relocdbci_s>:/export/sapmnt/<SID>
Add database specific filesystems to this files if they exist. This can be verified using the table in
chapter 2.
Usually the relocatable IP address of the database package or the SAPNFS package is used.
When configuring AUTOFS the automounter map file /etc/auto.direct must NOT be
executable. Make sure to set the appropriate permissions of /etc/auto.direct to 644.
Installation Step: IS840
Restart the automounter with: /sbin/init.d/nfs.autofs stop and
/sbin/init.d/nfs.autofs start.
WARNING! Never kill the automount process. Always use nfs.autofs to stop or start it.
WARNING! Never stop the NFS client while the automounter directories are still in use by some
processes. If nfs.autofs stop reports that some filesystems could not be unmounted, the automounter
may refuse to handle them after nfs.autofs start.
