OpenVMS VAXLAD02_071 OpenVMS VAX V7.1 LAD Drivers ECO Summary
TITLE: OpenVMS VAXLAD02_071 OpenVMS VAX V7.1 LAD Drivers ECO Summary
 
Modification Date:  06-OCT-1999
Modification Type:  Updated Kit:  SupersedeS VAXLAD01_071

NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       The name of the compressed file will be kit_name-dcx_vaxexe
       for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
 
       Once the file is copied to your system, it can be expanded
       by typing RUN compressed_file.  The resultant file will
       be the OpenVMS saveset or PCSI installation file which
       can be used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for SYS$DADDRIVER, SYS$LADDRIVER, SYS$LASTDRIVER, 
and SYS$MADDRIVER on OpenVMS VAX V7.1.  This kit addresses the 
following problems:

Problems Addressed in VAXLAD02_071 Kit:

  o  In a multi-processor environment, the service solicitation
     queues may be accessed by several processors.  Since these
     queues are not synchronized correctly, they can get corrupted.
     Thus, the system crashes with an INVEXCEPTN at around
     LASTDRIVER+3513 in routine LAST$TICK.

     Note:
       LAST should not be started on non-connected Ethernet
       controllers.  Otherwise, problems with the LADCP> SHOW 
       SERVICE command can occur.

     Image(s) Affected:   [SYS$LDR]ESS$LASTDRIVER.EXE

  o  If a tape is initialized on a TZ87 and then put on a TZ86 with
     an attempt to re-initialize the tape, the TZ86 takes an
     excessive amount of time to determine how to handle the tape.
     Hence, it times out.

     Image(s) Affected:  [SYS$LDR]ESS$MADDRIVER.EXE

  o  System crashes can occur when an attempt is made to create a 
     directory or write a file to a large InfoServer partition.

     Image(s) Affected:  [SYS$LDR]ESS$DADDRIVER.EXE


Problems Addressed in VAXLAD01_071:  

  o  The system crashes in LTDRIVER when SSB is deleted prematurely            
     while an UNLOAD is in progress.                                          
                                                                          
  o  LASTDRIVER crashes when it receives a run message in circuit          
     stalled state.                                                           
                                                                          
  o  The LASTDRIVER image crashes when it receives an Advertisement          
     (ADV) or Solicit (SOL) message with a negative message length.           
                                                                          
  o  An overrun error on magtape occurs if the record size is          
     greater than 65024.                                                      
                                                                          
  o  In the past, BIND/TAPE/NOPERMANENT "tape_service" created a          
     MADx device UCB that could be deleted once the UCB reference          
     count went to zero.  Problems occurred when the UCB was deleted          
     due to the use of the /NOPERMANENT qualifier, that is          
     multivolume BACKUP.                                                      
                                                                              
     Note:  A MAD device is a tape device that is attached to an          
     InfoServer                                                               
        

INSTALLATION NOTES:

The images in this kit will not take effect until the system is
rebooted.  If there are other nodes in the VMScluster, they must 
also be rebooted in order to make use of the new images.  

If it is not possible or convenient to reboot the entire cluster at 
this time, a rolling re-boot may be performed.
