ECO KIT SUMMARY:
An ECO kit exists for Y2K issues on ODS-1 on OpenVMS VAX V7.1. This kit
addresses the following problems:
Problems Addressed in this kit:
o The 64 bit internal time is not formatted to an RSX-11
compatible ASCII string. An RSX date string contains
only a 2-character year field (ASCII). In order to
accommodate the year 2000, this ASCII encoding will now
include the value of decades (since 1900) in the string.
This means that for the years 1900 through 1999, the date
string will appear as 00 to 99. For the years 2000 through
the years 39xx, the string will show as ':0', ';0' and so
forth.

o An INIT/STRUCTURE=1 command returns the following error:
%INIT-F-ILLBLKNUM, illegal logical block number
Images Affected: [SYSLIB]INIT$SHR.EXE
o Attempting to mount the second volume of a two-volume RMU
backup results in %MOUNT-F-MEDOFL and %MOUNT-F-FILACCERR
errors.
Images Affected: [SYSEXE]MTAAACP.EXE
o Verify does not flag files which are directly back linked to
themselves as having invalid backlinks.
Images Affected: [SYSEXE]VERIFY.EXE
o VERIFY hangs in an infinite loop during its scan of the
directory structure.
Images Affected: [SYSEXE]VERIFY.EXE
Problems Addressed in the VAXF11X05_071 Kit:
o When two processes are accessing a file via the MOVEFILE and
READATTR/FID_TO_SPEC mechanism, such as a data collector
process running on the same volume as a defragger competing
for the same data, both processes try to delete the 'primary_fcb'
used to get the information in question. In both of these
circumstances, the reference count on the FCB has not been bumped
up so both accesses appear to allow the deletion. This results
in a NOTFCBFCB Bugcheck.
Image(s) Affected: [SYS$LDR]F11BXQP.EXE
o If a process attempts to mount a Bound Volume Set (BVS) and
all the members of the BVS are not present, an attempt to lock
the volume for REBUILDing the meta-data on the volume will
fail, but the blocking lock (F11B$b) is left with the process.
Image(s) Affected: [SYS$LDR]F11BXQP.EXE
o An XQPERR Bugcheck occurs in LOCKERS when the retry limit on
F11B$x lock is reached. This happens when the owner of the $x
lock is running at a high process priority and there are a
number of processes in a clustered system that are also trying
to validate this lock but at a lower process priority. The
high priority process never really gives up the locks long
enough to let the low process priority processes to continue
and either validate or release the $v lock.
To avoid this situation, after (every) 256 attempts, the
process with the most retry iterations is stalled for a short
period to allow other processes to complete their accesses to
the lock.
Image(s) Affected: [SYS$LDR]F11BXQP.EXE
o When a directory with multiple headers, e.g., a large ACL, is
deleted on one mode in a cluster (Node A), if that directory
had previously been accessed on another node in the cluster
(Node B), the files created with the previously deleted
headers would show up on Node B with a NOSUCHFILE error."
Image(s) Affected: [SYS$LDR]F11BXQP.EXE
Problems Addressed in the VAXF11X04_071 Kit:
o During the mounting of the system disk, the error message that
the disk is mounted with a reduced cache is suppressed. Thus,
the System Manager may be unaware that the performance of the
system disk and all others attached to the same cache block is
questionable.
Image Affected: [SYSEXE]FILESERV.EXE
Note: [SYS$STARTUP]VMS$CONFIG-050_CACHE_SERVER.COM also is
needed to run the FILESERV.EXE image.
o When deleting a large file (such as a system dump file), a
UNXSIGNAL Bugcheck may occur. This particular bugcheck occurs
because a variable in the code causes a reference to memory
data that the file system does not own and an internal access
violation occurs (ACCVIO).
Image Affected: [SYS$LDR]F11BXQP.EXE
o On some systems with higher rates of system paging or with
WSDEC set to a non-standard value, a system can crash with a
PGFLIPLHI (Page Fault IPL too High) bugcheck. This problem
happened when the system returns from a SMP$ACQUIRE call.
Image Affected: [SYS$LDR]F11BXQP.EXE
o An XQPERR can occur in the RDBLOK module during disk cleanup
using DCL.
Image Affected: [SYS$LDR]F11BXQP.EXE
o When storing the value of a directory index buffer, the system
may crash with a PGFLIPLHI, SSRVEXCPTN error.
Image Affected: [SYS$LDR]F11BXQP.EXE
o A dismount on a shadowed device results in an unnecessary
copy.
Image Affected: [SYS$LDR]F11BXQP.EXE
o If a process is created with a termination mailbox unit
assigned, the files are not properly audited.
Image Affected: [SYS$LDR]F11BXQP.EXE
o An XQPERR bugcheck (crash) in the RETURN_CREDITS module can
occur during DISMOUNT.
Image Affected: [SYS$LDR]F11BXQP.EXE
o A XQPERR Bugcheck (crash) in XQP can occur during an SET ACL
(SET FILE/ACL) operation.
Image Affected: [SYS$LDR]F11BXQP.EXE
o When two processes are competing to dismount a volume, one
process may be just a bit faster than the other. This process
can delete the VCB and other structures before the second
process has time to finish up its processing. The result is
in an UNXSIGNAL/ACCVIO crash.
Image Affected: [SYS$LDR]F11BXQP.EXE
o A device reporting a read error (SS$_PARITY) during read/write
processing in the XQP will attempt to record the bad blocks
and FID in the BADLOG.SYS file. When the internal close
operation occurs (on BADLOG), the system XQPERR bugchecks
when it finds the process's dirty buffers have not been written
out.
Image Affected: [SYS$LDR]F11BXQP.EXE
o An UNXSIGNAL/ACCVIO error can occur at module F11BXQP. This
problem can occur during mount, when the primary volume is not
yet mounted.
Image Affected: [SYS$LDR]F11BXQP.EXE
o Processes can hang (deadlock) when dismounting a device.
Image Affected: [SYS$LDR]F11BXQP.EXE
o Alternate file access checking does not provide the correct
information for files on ODS-1 disks. That is, an ODS-1 disk
access does not process the alternate file access checking
parameters FIB$L_ALT_ACCESS and FIB$L_STATUS.
Image Affected: [SYSEXE]F11AACP.EXE
o The F11A routine ACPCONTROL only understands the control
function REMAP_FILE. Hence, for illegal function codes, all
other control functions return NORMAL, when ILLIOFUNC should
be returned instead.
Image Affected: [SYSEXE]F11AACP.EXE
o Occasional false end-of-file (EOF) errors can occur on a read
operation.
Image Affected: [SYS$LDR]F11BXQP.EXE
o The XQP fails after an IO$_DEACCESS call with an SS$_BADPARAM
error. One cannot determine whether a file is still open or
not due to the failed IO$_DEACCESS call.
Image Affected: [SYS$LDR]F11BXQP.EXE
o Non-privileged users can change the revision date (and count)
of a file for which they should have only READ access. For
example, if a non-privileged user with READ-only file access
tries to set the file protection, a failure occurs with an
SS$_NOPRIV error as expected. However, the revision date (and
count) are modified.
Image Affected: [SYS$LDR]F11BXQP.EXE
Problems Addressed in the VAXF11X03_071 Kit:
o A XQPERR bugcheck error "all the index buffers are active"
occurs typically when running with a reduced cache or during a
BACKUP.
o An XQPERR bugcheck error, 'wrong lock basis with FCB present',
occurred when creating files with ACLs on a full volume.
o One can serialize on the wrong volume in a volume set.
o If more than one process queues for a volume's activity
blocking lock, the XQP can deadlock.
o The user-mode crasher in VALIDATE_FILE needed to be fixed.
Specifically, the FIB$C_VALIDATE_FILE ACP control function
caused a bugcheck if called on a channel which was not
accessed.
o Various XQPERR bugchecks occur in directory scanning/shuffling.
o When a file with a version limit of 1 is created and SYSTEM_CHECK
is on or bit 5 or 6 of ACP_DATACHECK is 1, an XQPERR bugcheck
occurs due to a corrupted directory.
o The NOTIFY_USER for final status of an XQP request occurs too
early in XQP request completion to report any errors produced
in cleanup or auditing. This problem is normally all right,
since USER_STATUS is not expected to change during cleanup.
However, if it does change, then the output of SET WATCH FILE
is misleading.
o XQP requests to create a new file with version limits set can
fail with an SS$_NOSUCHFILE error.
o Deleting a stale alias on a directory with extension headers
can bugcheck with XQPERR "Lock index has shifted". This
problem occurs when:
1. an alias to an existing file is created,
2. the original file is deleted, and
3. the original file's file header is reused as an extension
header of the alias's parent directory (when ACEs are
added to the directory).
o Prevent access to file headers beyond index file
highwater-marking (HWM).
One can possibly ACCESS by FID a file header beyond the
current end of the index file on a freshly-initialized volume.
Creating a new file accessed in this way can bugcheck the
system with the XQPERR error.
o Fix a reserved operand fault bugcheck on $QIO exit. The $QIO
failed on return because the IPL was set to zero but was
entered at IPL 2.
o The code was in a pageable psect and managed to get paged out.
o $GET_SECURITY was reading the ORB on a file without any
synchronization with the filesystem. In the best case, this
problem can lead to bad information being returned. In the
worst case, if the filesystem was rebuilding the ORB's ACL
chain at the time, a kernel mode ACCVIO can occur.
*** Note: In order to get this fix, you must install the
VAXSYSA02_071 kit.
Problems Addressed in the VAXINIT01_071 Kit:
o A possible system crash occurs during Host Based RAID Unbinds
with MME code enabled. A mailbox read synchronization problem
causes the crash.
This problem only occurs when a host-based RAID UNBIND command
is done while an MME-based application is running.
This problem can occur in several different code areas of the
operating system. In order to eliminate all known instances
of this problem, the following remedial kits (or their
supersedants) will also need to be installed:
VAXSYSA02_071
VAXBACK03_071
VAXMOUN04_071
VAXDISM01_071
VAXMTAA01_071
Images Affected: [SYSEXE]INIT$SHR.EXE
o A process using MME could potentially "miss" the VOL1 label on
a tape. Also, a process could "hang" trying to send a message
to the MME process.
Problems Addressed in the VAXVERI01_071 Kit for OpenVMS VAX V6.1, V6.2,
V6.2-0HF, V7.0, V7.1:
o ANALYZE/DISK goes into an infinite loop.
VERIFY has incorrectly 'fixed' the backlink of a lost directory to
point to itself. The next time VERIFY is run, it encounters the
lost directory and goes into a tight loop following the directory's
backlink.
Images Affected: [SYSEXE]VERIFY.EXE
Problems Addressed in the VAXMTAA01_071 Kit:
o A possible system crash occurs during Host Based RAID Unbinds
with MME code enabled. A mailbox read synchronization problem
causes the crash.
This problem only occurs when a host-based RAID UNBIND command
is done while an MME-based application is running.
This problem may occur in several different code areas of the
operating system. In order to get eliminate all known
instances of this problem, the following remedial kits (or
their supersedants) will also need to be installed:
VAXSYSA02_071
VAXBACK03_071
VAXDISM01_071
VAXINIT01_071
VAXMOUN04_071
o A process using MME could potentially "miss" the VOL1 label on
a tape. Also, a process could "hang" trying to send a message
to the MME process.
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 image(s).
If it is not possible or convenient to reboot the entire cluster at
this time, a rolling re-boot may be performed.
