Use the License Management H               Utility (LMF) documentation to register and load a licenseH               PAK. You can install DECdfs software without a PAK but you1               cannot run the IVP or start DECdfs.            3 New Features  H               The following features are new in the DECdfs Version V2.4A               release:  6               o  Support for OpenVMS I64 Version 8.x-x8               o  Support for OpenVMS Alpha Version 8.x-x           4 Year 2000 Readiness   B               DECdfs has been investigated and is Year 2000 ready.I               However, you should be aware of a condition related to Year H               2000 handling. DECdfs uses the file system $QIO interface,I               which supports several attributes for RSX-11 compatibility. G               Of these, ATR$C_EXPDAT and ATR$C_ASCDATES return the file E               creation date, revision date, and expiration date using                2-digit years.  I                                                                         1           G               These attributes are not normally used by native code and F               can be replaced with the following documented, compliant               interfaces:                     ATR$C_CREDATE                  ATR$C_EXPDATE                  ATR$C_REVDATE           5 Installation  P               The DECdfs Version V2.4A software kit is named HP-VMS-DECDFS-A024,I               and consists of multiple savesets. Saveset A is used by all F               installations. Each supported platform uses one and onlyH               one of the other savesets. The installation procedure willG               automatically select and install the proper saveset after I               determining the OpenVMS version, CPU architecture, and type 4               of network software currently running.  B               You can install DECdfs software by using a VMSINSTAL/               command similar to the following:   E               $ @SYS$UPDATE:VMSINSTAL HP-VMS-DECDFS-A024 kit-location   >               The installation procedure determines the system6               configuration and asks for confirmation.  I               Refer to the DECdfs for OpenVMS Installation Guide for more                information.  A         5.1 Running the Installation Verification Procedure (IVP)   F               The IVP may be run at the conclusion of the installationI               (provided old DFS drivers are not loaded), or it may be run H               at a later time. Write access to a DECdns namespace is no H               longer required. It is only necessary for the operator to J               provide the name of a temporary access point which is added G               and then deleted for the test.  The IVP will also add and A               later remove a proxy for the operator if necessary.         	         2  s        #         5.2 Post-Installation Stepso  I               To start DECdfs software automatically on your system after E               completing the installation procedure, edit your system H               startup command file so that it invokes the DECdfs startup                command procedure.  *               @SYS$STARTUP:DFS$STARTUP.COM  D               If you are running DECnet Phase IV, put this statementI               after the statement that invokes the DECnet startup commandAF               file (STARTNET.COM). The DECnet software must be startedD               before the DECdfs software. If you are running DECnet B               Phase V, the DECdfs startup statement can be placed 7               anywhere within your SYSTARTUP procedure.u  E               If DECdns software is not available, the DECdfs startup2E               procedure issues an advisory message to that effect andS$               continues the startup.  %         5.3 Upgrading DECdfs Softwarea  H               This kit upgrades any previous version of DECdfs software.I               If possible, reboot your system before starting the upgrade C               and disable the startup of DECdfs. Typically, this iswH               accomplished by commenting out the call to DFS$STARTUP.COMG               in your SYSTARTUP procedure. Disabling an earlier versiondI               of DECdfs software ensures that incompatible DECdfs driversgH               and images are not loaded when Version V2.4A is installed.A               Because drivers cannot be unloaded or replaced, the E               presence of loaded drivers prevents the new DECdfs from C               being started and prevents the IVP from being run. IfdE               the system is rebooted before the installation, it does E               not need to be rebooted again after the installation is_F               completed. Otherwise, a reboot is necessary to place the#               new version into use..  I               If necessary, you can continue running your present versionaG               of DECdfs software during the Version V2.4A installation.oH               This might be necessary if the installation kit is locatedE               on a DECdfs-served disk. However, once the installationiE               is completed, DFSCP commands do not work because of the.C               incompatibility of new and old images. Therefore, thet<               system should be rebooted as soon as possible.  I                                                                         3n e        H               If the installation procedure finds DECdfs drivers alreadyF               loaded, it issues a warning, and allows the installer to1               abort or continue the installation.t  )         6 Known Problems and Restrictions   C               This section includes information about the following                topics:u  $               o  Backup Restrictions  ,               o  DECdfs Compatibility Issues                 o  No ACL Support   '               o  No Shared Write Access   :               o  DECnet Phase V Hidden Areas Not Supported  G               o  Upgrading a DECdfs Node from DECnet Phase IV to DECnet                   Phase V  ;               o  Use of STOP COMMUNICATIONS Not Recommended   6               o  DECdns and DECnet Phase V Search Path  9               o  Support for Extended File Specifications8           6.1 Backup Restrictionsa  G               DECdfs Version V2.4A software does not support the /FAST,iE               /IMAGE, and /PHYSICAL qualifiers to the BACKUP command.c  '         6.2 DECdfs Compatibility Issues   D               For each of the supported OpenVMS and DECnet versions,G               DECdfs Version V2.4A can work as a DECdfs client with any_                other as a server.  C               Any supported platform can also function as client or E               server with a platform running DECdfs Version 1.3, witheC               the limitation that DECdfs Version 1.3 clients cannot F               mount disks served by OpenVMS Alpha DECnet servers. ThisI               is because the new MOUNT qualifier, /NODE, is not available %               on Version 1.3 clients.   I               Where a Version V2.4A client is used with a Version 2.1, ordB               earlier server, directory creation is not supported.  	         4i s                 6.3 No ACL Support  E               The use of ACLs is unsupported on DECdfs mounted disks.   "         6.4 No Shared Write Access  F               When a user has a file open for writing, no other DECdfsG               access is allowed. If a DECdfs user has the file open for B               writing, no other local or DECdfs access is allowed.  5         6.5 DECnet Phase V Hidden Areas Not Supported   C               DECdfs does not support client access from, or server C               access to, nodes in DECnet Phase V hidden areas. This E               situation arises only when a DECnet network with hidden @               areas has added some nodes running DECnet Phase V.  J         6.6 Upgrading a DECdfs Node from DECnet Phase IV to DECnet Phase V  I               If a DECdfs server node running DECnet Phase IV is upgradediE               to DECnet Phase V, it is important to remove all of thehI               access points served by that system before shutting it down G               for the upgrade. If this is not done, the name server may G               refuse to register the access points under DECnet Phase VeF               because the node name has a different syntax and format.E               Use the REMOVE ACCESS_POINT command, giving each access 4               point name that is served by the node.  D               After the DECnet Phase V upgrade and reinstallation ofI               DECdfs, the normal server startup procedure reregisters theo1               access points with the name server.v  I               In any other case where a server permanently ceases servingeH               an access point, the REMOVE ACCESS_POINT command should be2               used before the server is shut down.  6         6.7 Use of STOP COMMUNICATIONS Not Recommended  D               HP recommends using the SHUTDOWN COMMUNICATION commandC               instead of STOP COMMUNICATION. The STOP COMMUNICATIONsC               command stops communication as soon as the command iseD               entered and aborts all existing connections regardlessD               of whether an operation is in progress. This may causeF               processes to hang or the system to crash. In contrast toD               STOP COMMUNICATION, SHUTDOWN COMMUNICATION initiates aE               controlled shutting down of services and does not aborteD               user operations. It causes the Communication Entity toF               refuse new requests and then to stop communication when (               all open files are closed.  I                                                                         5           1         6.8 DECdns and DECnet Phase V Search Pathe  H               On a system running DECnet Phase V, if you wish to mount aG               DECdfs access point registered in a DECdns namespace, youoF               must include DECdns in the session control naming searchC               path. This can be done using NET$CONFIGURE to specifyuI               DECdns as one of the directory services. Otherwise, includelF               the /NODE qualifier in your DFS MOUNT command to specifyE               the node serving the access point. Failing to do eitherw<               will result in a %DFS-E-CVT_TO_DNS_NAME error.  4         6.9 Support for Extended File Specifications  C               DECdfs for OpenVMS Version V2.4A provides support for B               Extended File Specifications and ODS-5 volumes, withF               certain restrictions. Only OpenVMS Alpha Version 7.2 (orF               later) systems running DECdfs Version 2.3 (or later) areD               capable of serving and mounting access points on ODS-5I               volumes. If a pre-Version 7.2 client running DECdfs Version$G               2.3 (or later) attempts to mount a DECdfs access point on,E               an ODS-5 volume, the operation fails with the following.               error:  C                  %DFS-F-UNSUPPFS, Unsupported file system structure   H               A client system running an older version of DECdfs fails  I               with a different error on an attempt to mount or access an  -               ODS-5 access point, as follows:E  I                  %SYSTEM-E-UNSUPPORTED, unsupported operation or function   H               On OpenVMS VAX Version 7.2 and 7.3 systems, you can mount H               DECdfs access points on ODS-5 volumes, but you are limited1               to ODS-2-compliant file operations.i  I               If both server and client systems are running OpenVMS AlpharG               Version 7.3-1, DECdfs Version V2.4A provides support for eG               access dates and hardlinks.  Enabling or disabling these  G               volume characteristics must be done on the server system.fI               Once changed, the access point must be remounted to reflecty               the new settings.             	         6f o        4         7 Support for DECnet-over-TCP/IP connections  E               DECnet-Plus has the ability to make DECnet connections  D               to another node over a TCP/IP network if both systems F               involved are running DECnet-Plus along with a compatibleD               TCP/IP product.  In addition, the TCP/IP product must @               contain and be configured to load a PWIP driver.    H               Once DECnet-Plus and TCP/IP have been properly configured,C               DECdfs is able to utilize this capability.  To force .E               DECdfs to make a DECnet connection over TCP/IP, use theeE               /NODE qualifier on the DFS MOUNT command to specify the 5               DECdfs server's domain name or address.                  For example:  C               DFS> MOUNT DFSTEST:.HOST_TEST1 /NODE=HOST.EXAMPLE.COMyI               %MOUNT-I-MOUNTED, DFSTEST:.HOST_TEST1 mounted on _DFSC1386:.  >               DFS> MOUNT DFSTEST:.HOST_TEST2 /NODE=16.12.34.56I               %MOUNT-I-MOUNTED, DFSTEST:.HOST_TEST2 mounted on _DFSC1387:l  B               Note that in order to use a domain name, the domain D               directory service must be included in the DECnet-Plus E               Session Control NAMING SEARCH PATH and BACKTRANSLATION u*               SEARCH PATH characteristics.                                        I                                                                         7.
