Configuring HA HP CIFS
Special Notes for HA HP CIFS Server

You may want to put the entire /var/opt/samba/locks directory on a
logical shared volume but the locking data may not be correctly
interpreted after a failover. You may want to add a line to your
startup script to remove the locking data file .../locks/locking.tdb.
• Samba as a WINS Server
If you configure your Samba server to be a WINS server by setting
the wins support parameter to yes, it will store the WINS database
in the file /var/opt/samba/locks/WINS.DAT.
If this file is not on a logical shared volume, when a failover occurs,
there will be a short period of time when all the WINS clients update
the Samba WINS server with their address. However, if this short
period of time to restore the WINS database is not acceptable, you
can reduce the period of time to restore the full WINS service.
To do so, configure /var/opt/samba/locks/WINS.DAT to be a
symbolic link to a WINS.DAT file on a logical shared volume. HP
does not recommend putting the entire /var/opt/samba/locks
directory on a logical shared volume, because the locking data may
not be correctly interpreted after a failover.
• Samba as a Master Browser
If you configure your Samba server to be the domain master browser
by setting the domain master to yes, it will store the browsing
database in the /var/opt/samba/locks/BROWSE.DAT file. HP does
not recommend doing this in an HA configuration.
If you do so, you will probably want to configure
/var/opt/samba/locks/BROWSE.DAT as a symbolic link to a
BROWSE.DAT file on a logical shared volume. HP doesn’t
recommend putting the entire /var/opt/samba/locks directory on a
logical shared volume because the locking data may not be correctly
interpreted after a failover.
• Automatic Printer Sharing
If you configure your Samba server with a [printers] share to
automatically share all the printers on your HP-UX system, then you
will need to be certain that all your MC/ServiceGuard nodes have the
same HP-UX printers defined. Otherwise, when a failover occurs, the
list of shared printers for the Samba server will change, resulting in
problems on clients using those printers.
