Updating from version A.01.07 or earlier

Please consider the following issues when updating:

Printer Driver

If you do not intend to use the new Windows NT/XP/2000 printer driver support feature, nothing should be done. All of the existing configuration parameters for printer services will continue to work as before
If you want to take advantage of the new NT/XP/2000 printer driver support features, but do not want to update the Windows 9x drivers to the new setup, then use the existing printers.def file
If you install a Windows 9x driver for a printer on the HP CIFS Server, the new setup information will take precedence, and the three old parameters (printer driver, printer driver file and printer driver location) will be ignored
If you have a printer installed on a HP CIFS Server version A.01.07 or below, and you update to Server version A.01.08 or higher, you must reboot the Windows client to make the printer work under version A.01.08 or higher

Configuration

smbpasswd file required for use in POSIX ACL management
HP-UX users must be entered into the smbpasswd file in order to properly enumerate user names when manipulating POSIX ACLs. Unlike previous versions that directly queried the UNIX user database, version A.01.08 and higher will always access the smbpasswd file when displaying user names on the local machine. The command line tool syncsmbpasswd is provided to help populate the smbpsswd file.

Kernel Parameters
HP CIFS Server, version A.01.08 and higher, utilizes system resources differently from previous versions. The following HP-UX kernel parameters must be adjusted accordingly:
- NFILES - total number of open files per system
  Each smbd process will initially open 23 files for internal use. However, clients will open more files during a session. Therefore, as a minimum, the number of nfiles should be:
  nfiles = (23 + max_client_files) * max_connected_clients
  NOTE: Previous CIFS Server versions used 8 files for internal use.
- NFLOCKS - total number of file locks per system
  At least ten (10) file locks are allocated per smbd process for internal use. Clients may need additional locks depending on the applications used. Therefore, as a minimum, the number of nflocks should be:
  nflocks = 10 * max_connected_clients
  NOTE: Previous CIFS Server versions did not require explicit configuration of this parameter.
These guidelines for minimum parameter values account for HP CIFS Server usage of system resources only. Other applications and system processes may require further increases in the value of these parameters.

Memory Requirements

Each connected client will use a minimum of 1MB of memory. This is approximately double the usage of version A.01.07. For example, a system expecting 1024 connected clients should have at least 1 GB of physical memory. This is over and above the requirements of other applications that will be running concurrently with CIFS Server.




	NOTE: Using a very large smb.conf file can significantly increase memory utilization. Therefore, it is good practice to minimize unnecessary lines in the smb.conf file. One way to achieve this is to use the SWAT utility for configuration.
