OpenVMS VMS73_SYS-V0500 Alpha V7.3 System ECO Summary
TITLE: OpenVMS VMS73_SYS-V0500 Alpha V7.3 System ECO Summary
NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       For OpenVMS savesets, the name of the compressed saveset
       file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or
       kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS
       saveset is copied to your system, expand the compressed
       saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe.
       For PCSI files, once the PCSI file is copied to your system,
       rename the PCSI file to kitname.pcsi-dcx_axpexe or
       kitname.pcsi-dcx_vaxexe, then it can be expanded by typing
       RUN kitname.pcsi-dcx_axpexe or kitname.pcsi-dcx_vaxexe.  The
       resultant file will be the PCSI installation file which can be
       used to install the ECO.

Modification Date:  13-DEC-2002

*									 *
*  After installing the DEC-AXPVMS-VMS73_SYS-V0500--4.PSCI ECO kit, 	 *
*  customers may experience process hangs when using SMTP mail.		 *
*									 *
*  When sending a mail message via SMTP,  the mail is delivered but 	 *
*  the process handling SMTP mail delivery hangs on creating the mail 	 *
*  notification.The mail delivery notification is never sent and any 	 *
*  subsequent SMTP mail accumulates, unsent, in the queue.		 *
*									 *
*  The process hangs occur because BRKTHR tries to allocate memory 	 *
*  from P1 space. If it is unsuccessful, it tries to allocate from 	 *
*  P0 space.  This is when the hangs occur.				 *
*									 *
*  Workaround:								 *
*									 *
*  Increasing the size of CTLPAGES will provide more P1 space and help	 *
*  alleviate the process hangs.						 *
*									 *
*  If you have experienced these hangs and have undelivered SMTP mail 	 *
*  messages in the queue, executing the following command procedure, 	 *
*  in batch, on each node with a problem, will clear the mail messages.	 *
*  To use this command file substitute "node" with the name of the 	 *
*  system. Note that the lines enclosed by "[ ]" are optional.  They 	 *
*  are used if you wish to list multiple nodes. 			 *
*									 *
*  $SET NOON								 *
*  $TCPIP STOP MAIL							 *
*  $stop/que/reset TCPIP$SMTP_node_01					 *
*  [$stop/que/reset TCPIP$SMTP_node_02]					 *
*  $tcpip anal mail/repair						 *
*  $start/que TCPIP$SMTP_node_01					 *
*  [$start/que TCPIP$SMTP_node_02					 *
*  $TCPIP START MAIL							 *
*  $ sho que TCPIP$SMTP_node_01/full/all				 *
*  [$ sho que TCPIP$SMTP_node_02/full/all]				 *
*  $exit								 *
*									 *
*									 *
*  This problem will be addressed in the next  SYS ECO kit.		 *

       In order to receive all the corrections listed in this
       kit, the following remedial kits, or later, should also be installed:



An ECO kit exists for System components on OpenVMS Alpha V7.3.  
This kit addresses the following problems:


  o  On  a  multi-processor  machine,  in  a  small  cluster,  when
     creating or updating a clusterwide logical name, a process may
     hang in RWSCS state.

          Images Affected: [SYS$LDR]SYS$CLUSTER.EXE

  o  The  system  can  crash  with   a   BADDALRQSZ   bugcheck   in
     EXE$DEANONPGDSIZ_C.   In  some, but not all cases, the current
     process is CLUSTER_SERVER.  In cases where the current process
     is  not  CLUSTER_SERVER,  the  stack  will  have  addresses in

          Images Affected:[SYS$LDR]SYS$CLUSTER.EXE

  o  F$GETSYI('RAD_MAX_RADS',node) fails  to  get  the  information
     from   the  specified  node.   Instead,  the  command  returns
     information from the current node the command is executing on.

     Note that with OpenVMS versions  before  V7.3-1,  RAD_MAX_RADS
     will return 1 if there is no RAD support, and will return 8 no
     matter how many QBBs are physically present.  This  limitation
     was  documented  in  the  V7.2-1H1R  New  Features and Release
     Notes, June 2000, section

          Images Affected:[SYS$LDR]SYSGETSYI.EXE

  o  The system can crash with a FILCNTNONZ bugcheck.

          CrashDump Summary

  o  The system can crash with a CWLNMERR bugcheck.  The failing PC
     is in the LOGICAL_NAMES executive image.

          Images Affected:[SYS$LDR]LOGICAL_NAMES.EXE

  o  A program using C signals can be aborted  with  the  condition
     code set to the C signal value.

          Images Affected:[SYS$LDR]EXCEPTION.EXE

  o  The system can crash with  an  SSRVEXCEPT,  Unexpected  system
     bugcheck at EXE$IO_PERFORM_C+00650

          Crashdump Summary Information:
          Bugcheck Type:    SSRVEXCEPT, Unexpected system

          Offset:           00017EB0

          Failing Instruction:
          EXE$IO_PERFORM_C+00650: LDQ  R18,#X0108(R18)\

          Images Affected:[SYS$LDR]IO_ROUTINES.EXE

  o  An SSREXCEPT bugcheck in MMG_STD$IOLOCK_BUF if it  must  fault
     in the affected page.

     Section  2.2.1  of  the  OpenVMS  Alpha  Guide  to   Upgrading
     Privileged  Code Applications describes how device drivers can
     lock  down  multiple  I/O  buffers  using   IRPEs   with   the
     EXE_STD$READLOCK,    WRITELOCK,    or   MODIFYLOCK   routines.
     Unfortunately, when an IRPE  was  passed  in  and  the  buffer
     required  a  page  fault this code used the IRP$PS_FDT_CONTEXT
     offset on the IRPE, which is only valid on an IRP.

     The correction for this problem is to delay  the  use  of  the
     IRP$PS_FDT_CONTEXT  cell  until after the original IRP pointer
     has been restored by a call to the error call back routine.

          Images Affected:[SYS$LDR]IO_ROUTINES.EXE

  o  If there is a lot of cluster-wide $GETJPI activity, a  process
     may   hang  waiting  for  the  completion  of  an  RMS  $FLUSH
     operation.  The I/O  request  resulting  from  this  may  wait
     forever because the IOSB is not filled in.

          Images Affected:[SYS$LDR]PROCESS_MANAGEMENT.EXE

  o  A system that supports NUMA and has RAD_SUPPORT  enabled,  can
     crash  with  an  INVEXCEPTN  bugcheck  when the swapper is the
     current  process.   The   failing   PC   is   at   or   around

          Images Affected:[SYS$LDR]SYS$VM.EXE

  o  If a "space" pattern string is  combined  with  an  NEQ  match
     qualifier,  the  expected results of all processes will not be

          Images Affected:[SYS$LDR]PROCESS_MANAGEMENT.EXE

  o  Under some circumstances lookup of a device may fail.  If  the
     system doing the lookup has a zero allocation class specified,
     and attempts to  access  an  MSCP-served  disk  by  using  the
     NODE$DUA form, the access may fail because the device will not
     be found.

     This can be seen  in  the  following  SET  VOLUME/REBUILD  DCL
     example  (SHOW  DEVICE  fields  have  been  edited  for  space

          $ SHOW DEVICE $8$DUA10

          Device               Device           Error    Volume
          Name                 Status           Count    Label

          $ WRITE SYS$OUTPUT F$GETDVI("_utramp$dua10:","EXISTS")
          $ SET VOLUME/REBUILD $8$DUA10:
            %SET-E-NOTSET, error modifying _UTRAMP$DUA10:
            -RMS-F-DEV, error in device name or inappropriate
            device type for operation
            %SET-E-NOTSET, error modifying _UTRAMP$DUA10:
            -SYSTEM-W-NOSUCHDEV, no such device available

          A    lookup    via    the     runtime     library     function
          LIB$FIND_IMAGE_SYMBOL will also show the problem.

          Images Affected:[SYS$LDR]IO_ROUTINES.EXE

  o  PWRK$STREAMSOS_V7.EXE is a big  file,  about  1760  blocks  in
     size.    If   this  file  has  become  very  fragmented  after
     installation then Advanced server  startup  may  fail  with  a
     SS$_BADPARAM  error.   This can occur if PWRK$STREAMSOS_V7.EXE
     is heavily fragmented  and  has  multiple  file  headers  (the
     following example has been modified for space reasons):

          $ @sys$startup:pwrk$startup
          The file server will use DECnet, TCP/IP.
          Advanced Server mail notification will use DECnet.

 o  Lock manager and nonpaged pool usage may  increase  over  time
    due  to  a  memory  leak  of lock blocks (LKB) and AST control
    blocks (ACB64).  This lock manager leak only occurs under very
    specific   circumstances  which  are  not  that  common.   The
    specific circumstances are the $DEQ of a  process  based  lock
    with a pending completion AST that has not yet been delivered.

  o  Doing I/O on a multipath device, when the current  path  is  a
     secondary,  results  in  an increase in the UCB$L_OPCNT in the
     primary as  well  as  the  current  path  UCB.   Although  the
     UCB$L_OPCNT in the secondary grows faster than in the primary,
     the UCB$L_OPCNT in the primary should not be changing (except,
     at  most  by  once  per  second  for  polling.) This is easily
     observed when doing a DIR/SIZE on the system disk.

     A number of customers and third-parties rely on these counters
     to  be  accurate  in  their  performance and capacity planning

     often crash with an Invalid exception error.

  o  On a system that contains a CPU numbered 31, CPU #31 can run a
     thread  even  if  that thread has specified, either by setting
     required capabilities or hard affinity, that it  must  run  on
     another  CPU.   Thus,  some  functions  which  must run on the
     primary CPU may occasionally be run on CPU  #31.   There  need
     not actually be 31 CPUs.  This bug can cause problems with CPU

  o  On NUMA systems, at the end of the system startup, unused PFNs
     are  released for the exec data huge page region, and then the
     exec  code  and  resident  code  region  will  be  replicated.
     Customers  having  their own drivers, which can be reloaded on
     the  fly,  need  to  clear  the  RELEASE_PFNS   bit   in   the
     LOAD_SYS_IMAGES  SYSGEN  parameter to avoid releasing PFNs for
     the exec data region.  Otherwise the driver reload fails  with
     an error.

     This change stops release of PFNs for the  exec  data  region.
     This  allows  customers to reload drivers on the fly and still

This kit requires a system reboot.  Compaq strongly recommends that
a  reboot  is performed immediately after kit installation to avoid
system instability

If you have other nodes in your OpenVMS cluster, they must also  be
rebooted  in  order  to make use of the new image(s).  If it is not
possible or convenient to reboot the entire cluster at this time, a
rolling re-boot may be performed.


Install this kit with the POLYCENTER Software installation  utility
by logging into the SYSTEM account, and typing the following at the
DCL prompt:

     PRODUCT INSTALL VMS73_SYS /SOURCE=[location of Kit]

The kit location may be a tape drive, CD, or a disk directory that
contains the kit.

Additional help on installing PCSI kits can be found by typing
HELP PRODUCT INSTALL at the system prompt


  o  Scripting of Answers to Installation Questions

     During installation,  this  kit  will  ask  and  require  user
     response  to  several  questions.  If you wish to automate the
     installation of this kit and avoid having to provide responses
     to  these  questions,  you must create a DCL command procedure
     that includes the following definitions and commands:



           -  Add  the  following  qualifiers  to  the  PRODUCT  INSTALL
              command and add that command to the DCL procedure.


           -  De-assign the logicals assigned

     For  example,  a  sample   command   file   to   install   the
     VMS73_SYS-V0500 kit would be:

          $ exit
