ECO KIT SUMMARY:
An ECO kit exists for SCSI Devices (DKDRIVER, MKDRIVER, PKBDRIVER,
PKCDRIVER, PKIDRIVER, PKRDRIVER, PKSDRIVER) on OpenVMS VAX V5.5-2
through V6.1.
Problems Addressed in the VAXSCSI03_061 Kit for OpenVMS VAX V6.0 and
V5.5-2H4:
o In certain heavily-loaded situations, TZ30 transfers can time out
with the current DMA TIMEOUT of 3 seconds. The fix increases the
DMA TIMEOUT in SCSI_CMD for the port driver, to 10 seconds.
Problems Addressed in the VAXSCSI03_061 Kit for OpenVMS VAX V6.1 and
V5.5-2H4:
o Under heavy load, the fifteenth synchronous data transfer may not
be counted by the NEC 53C94 chip. This will cause the process
associated with the transfer to hang or for a SCSI bus reset to
be issued and mount verification invoked.
o Following a SCSI bus reset, read commands which can fail due to
the bus reset cause system code to bugcheck. This is caused by
a Page Read Error problem.
Problems Addressed in the VAXSCSI02_061 Kit for OpenVMS VAX V5.5-2,
V5.5-2H4, V6.0, and V6.1:
o Some devices reply to Inquiry commands with the response data
format field set to SCSI-1 (as opposed to CCS or SCSI-2).
This setting causes these devices to be marked as offline.
Problems Addressed in the VAXSCSI02_061 Kit for OpenVMS VAX V6.1:
o Magnetic tapes with odd byte block sizes cause the DUMP
utility to report data overrun errors.
Problems Addressed in the VAXSCSI02_061 Kit for OpenVMS VAX V5.5-2H4
and V6.1:
o The port driver does not properly detect and handle the queue
full condition for TCQ operation.
o Under heavy loads the command complete interrupt for an AEN
finish command operation can occur prior to the fork level
code releasing the port. This causes the interrupt to be
misinterpreted and an INCONSTATE bugcheck occurs.
o When a process executes a Diagnose command which results in a
SCSI check condition and exits without requesting sense data,
DKDRIVER will reject all future Diagnose commands with
SS$_CHANINTLK errors.
Problems Addressed in the VAXSCSI02_061 Kit for OpenVMS VAX V5.5-2:
o The SCSI magtape class driver does not allow for the skipping
of files by filemarks instead of by records.
o The system may crash when I/O is canceled on SCSI tape devices.
Problems Addressed in the VAXSCSI01_061 Kit for OpenVMS VAX V5.5-2,
V5.5-2H4, V6.0, V6.1:
o When multi-volume backups are performed using data compaction,
the compaction switch is turned off after completion of the
first volume.
Problems Addressed in the VAXDRIV10_U2055 Kit for OpenVMS VAX V5.5-2
(PKIDRIVER and PKSDRIVER):
o Data corruption might occur on read operations for segmented
transfers.
Problems Addressed in the VAXDRIV05_U2055 Kit for OpenVMS VAX V5.5-2
(PKIDRIVER and PKSDRIVER):
o PKIDRIVER and PKSDRIVER have a number of odd-byte transfer
problems, showing up as the last byte of a read being corrupted
on certain transfer sizes and segmented transfers.
Problems Addressed in the VAXDRIV09_U2055 Kit for OpenVMS VAX V5.5-2
(PKCDRIVER):
o When the PKCDRIVER times out waiting for a re-selection
interrupt, the correct value is not restored to R5.
This causes the system to crash.
Problems Addressed in the VAXDRIV08_U2055 Kit for OpenVMS VAX V5.5-2
(PKBDRIVER, PKCDRIVER, PKRDRIVER, and MKDRIVER):
o Under a heavy SCSI load, the Receive Diagnostic Command
to the TZK50 causes the SCSI bus to fail with a GROSS error.
This command is used to retrieve the hardware/firmware
revision level from the TZK50.
o Even though data read or written over the SCSI bus is
correct and the data read into the user buffer is
correct, Write/Read Check errors occur for one byte
data transfers.
o If the PCKDRIVER times out while waiting for a
reselection interrupt, the system will crash due to
an invalid R5 value.
Problems Addressed in the VAXDRIV06_U2055 Kit:
o The disconnect timeout period specified in the MKDRIVER
is not long enough to allow an INIT/ERASE operation to
complete on a 90 meter tape (TLZ06). This causes
ERASEFAIL and CTRLERR errors to be returned. For
example:
$ INIT/ERASE MKA500: test
%INIT-W-ERASEFAIL, volume not completely erased
-SYSTEM-F-CTRLERR, fatal controller error
%INIT-F-CTRLERR, fatal controller error
This problem is fixed in OpenVMS VAX V6.0.
o When performing a BACKUP to a TK50 tape on a SCSI drive,
POSITERR and DRVERR errors are returned if an attempt is
made to add a second saveset on the same tape. For example:
$ BACKUP/LOG R*.COM MKB500:ONE.SAV/SAVESET/NOREWIND/LABEL=TEST
$ BACKUP/LOG S*.COM MKB500:TWO.SAV/SAVESET/NOREWIND/LABEL=TEST
%BACKUP-F-POSITERR, error positioning MKB500:[000000]TWO.SAV;
-SYSTEM-F-DRVERR, fatal drive error
NOTE: When this condition occurs, the system error log also
will contain the following port error:
SCSI PORT SUB-SYSTEM, UNIT_MCY3$PKB0:
ERROR TYPE 0906
SCSI BUS PHASE ERROR
PHASE CHANGE TIMEOUT DURING COMMAND OUT
SCSI ID 05
o A DRVERR error has always been reported in MK for BLANK
CHECK errors. However, when initializing a new tape
volume during a multi-volume BACKUP, this error causes
the BACKUP operation to fail. To fix this problem, an
OPINCOMPL error is now returned. This error message
allows backup to completed and is also compatible with
other non-SCSI drivers.
o In certain heavily-loaded situations, TZ30 transfers could
time-out with the current DMA TIMEOUT of 3 seconds. This
fix increases the DMA timeout in SCSI_CMD for the port
driver to 10 seconds.
Problems Addressed in the VAXDRIV02_U2055 Kit for OpenVMS VAX V5.5-2
(PKBDRIVER, PKCDRIVER, PKRDRIVER, and MKDRIVER):
o When multiple logical units (LUNs) are connected on a SCSI
device, the device may enter into a Mount Verification state.
o The status returned when issuing a QIO to a powered-off device
(one which was powered on long enough to be configured
properly) through PKCDRIVER (SS$_CTRLERR) is inconsistent with
that returned by PKNDRIVER (SS$_TIMEOUT).
o Coding errors in PKCDRIVER cause unexpected errors when used
with user written class drivers.
o The PKCDRIVER register dump routine increments the address of
the error log buffer as a byte (INCB) instead of a longword
(INCL). This makes it possible for the address to wrap around
at the low byte boundary and corrupt the error log buffer.
o A single TurboChannel interrupt occurs twice on the VAXstation
4000 Model 90. The VAXstation 4000-90 CPU latches the
TurboChannel interrupt and the port driver does not clear the
latched bit. As soon as the interrupt is serviced and the IPL
is dropped, the interrupt shows up again.
o The peak 5Mb/Second data rates aggravate signal integrity
issues in certain maximum length cable configurations on
the VAXstation 4000 Model 90 and the VAXstation 4000
Model 60.
o Code from PKNDRIVER which is imported into PKCDRIVER at
PK$ABORT causes various problems, particularly with command
queueing enabled.
Problems Addressed in the VAXDRI03_2H4055 Kit for OpenVMS VAX
V5.5-2H4 (DKDRIVER, MKDRIVER, and PKxDRIVER):
o The last byte is sometimes corrupted on read operations for
segmented transfers.
o Devices which reply to Inquiry commands with the response data
format field set to SCSI-1 (as opposed to CCS or SCSI-2) are
mistakenly marked off line. A SONY[R] optical disk drive has
recently been found which responds with the SCSI-1 setting
instead of the CCS setting.
o Magnetic tapes with odd byte block sizes cause the DUMP utility
to report data overrun errors.
o The fork block at the end of the SPDT data structure is not
receiving an initial fork IPL/lock value. This results in
intermittent system crashes.
Problems Addressed in the VAXDRI02_2H4055 Kit for OpenVMS VAX
V5.5-2H4 (DKDRIVER, MKDRIVER, PKDRIVER, and PKSDRIVER):
o DKDRIVER Mode Sense, Mode Select and other fixes:
+ Some newer Seagate drives are off-line at boot time. These
drives worked with OpenVMS VAX V5.5-2 and OpenVMS VAX V6.0.
+ Mode sense data errors occur while configuring or mounting
some SCSI devices, particularly those which support Tagged
Command Queueing.
+ Multiple Mode Select failure device errors occur configuring
and accessing disks through an HSC40.
+ I/O operations which complete with a sense key of 00 cause
the I/O to fail and the device to be marked off-line. A
SWAPPER bugcheck sometimes occurs. The error log will show
a CHECK CONDITION returning a sense key of 00.
+ When using the IO$_DIAGNOSE interface to DKDRIVER, normal
access to the device will sometimes stall even if no CHECK
CONDITION has occurred.
o MKDRIVER/PKCDRIVER Fixes:
+ MKDRIVER:
- The Receive Diagnostic Command in the Packet Acknowledgment
sequence to a TZK50 causes the SCSI bus to fail with a GROSS
error during the DATA IN phase of the command from the target.
This error condition is only reproducible with heavy SCSI load.
- MKDRIVER does not check for canceled I/O before attempts
are made to use the IRP in the IO_SENSECHAR: routine.
+ PKCDRIVER:
- Write/Read Check errors occur for one-byte transfers even
though the data read or written over the SCSI bus is
correct and the data read into the user buffer is correct.
- When the driver times out waiting for a re-selection
interrupt, the correct value is not restored to R5.
This causes the system to crash.
o PKCDRIVER Fixes:
+ A SCSI command is read back as data but is not detected as
such by the driver.
+ On an invalid map interrupt at the label INVALID_MAP_INT,
the driver overwrites R1, which contains a valid value for
EXE$GL_CPUNODSP. This causes a crash when the mainline
driver code references an offset off R1.
+ When the DISP_INTERRUPT macro is invoked, the illegal
command (ILL_CMD) branch is re-tried instead of
taking the GROSS_ERR branch.
o There is a PKSDRIVER odd byte problem in the DATAI_PHASE routine.
o MKDRIVER: Provide a check for canceled I/O before attempting to
use the IRP in the IO_SENSECHAR routine.
o PKCDRIVER corrupts the first 24 bytes of the SPDT by using it as
a fork block when it forks to flush an I/O queue on an error
(SCSI reset). (SPDT$L_FQFL).
Problems Addressed in the VAXDRIV04_060 Kit for OpenVMS VAX V6.0
(PKIDRIVER and PKSDRIVER):
o Data corruption might occur on read operations for segmented
transfers.
Problems Addressed in the VAXDRIV03_060 Kit for OpenVMS VAX V6.0
(PKBDRIVER, PKCDRIVER, and PKRDRIVER):
o When the PKCDRIVER times out waiting for a re-selection
interrupt, the correct value is not restored to R5.
This causes the system to crash.
Problems Addressed in the VAXDRIV01_060 Kit for OpenVMS VAX V6.0
(PKBDRIVER, PKCDRIVER, and PKRDRIVER):
o The peak 5Mb/Second data rates aggravate signal integrity
issues in certain maximum length cable configurations on
the VAXstation 4000 Model 90 and the VAXstation 4000
Model 60.
o Code from PKNDRIVER which is imported into PKCDRIVER at
PK$ABORT causes various problems, particularly with command
queueing enabled.
Problems Addressed in the VAXDRIV03_061 Kit for OpenVMS VAX V6.1
(DKDRIVER, PKIDRIVER, and PKSDRIVER):
o I/O operations which complete with a sense key of 00 cause the
I/O to fail and the device to be marked off-line. A SWAPPER
bugcheck sometimes occurs. The error log will show a CHECK
CONDITION returning a sense key of 00.
Problems Addressed in the VAXDRIV02_061 Kit for OpenVMS VAX V6.1
(DKDRIVER, PKIDRIVER, and PKSDRIVER):
o Data corruption might occur on read operations for segmented
transfers.
INSTALLATION NOTES:
In order for the corrections in this kit to take effect, the system
must be rebooted. If the system is a member of a VAXcluster, the
entire cluster should be rebooted.
