OpenVMS VAXSCSI02_071 VAX V7.1 SCSI Driver ECO Summary
TITLE: OpenVMS VAXSCSI02_071 VAX V7.1 SCSI Driver ECO Summary
Modification Date: 22-SEP-1999
Modification Type: Updated Kit: Supersedes VAXSCSI01_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 SCSI Devices on OpenVMS VAX V7.1. This kit
addresses the following problems:
Problems addressed in VAXSCSI02_071 kit:
o If a TZ87 is powered off and on after system boot, a MOUNT
command issued to the device will cause the process to hang.
Hence the MOUNT never completes.
Image(s) Affected:
- [SYS$LDR]PKBDRIVER.EXE
- [SYS$LDR]PKCDRIVER.EXE
- [SYS$LDR]PKRDRIVER.EXE
o An attempt to mount a disk device can fail with an MEDOFL
error if the device returns the minimum amount or required
mode sense data.
Image(s) Affected: [SYS$LDR]DKDRIVER.EXE
o The system can bugcheck with an ACCVIO. The program counter
of the crash is usually in the middle of the structure or some
other unexpected address.
Image(s) Affected: [SYS$LDR]DKDRIVER.EXE
o The System can crash with an INVEXCEPTN in the DKDRIVER
DK_CANCEL routine if a stale IRP resides in UCB$L_IRP when a
cancel occurs. (This problem can happen frequently with a
product called ENTIA.)
Image(s) Affected: [SYS$LDR]DKDRIVER.EXE
o Disk drives with a capacity of greater than 8.6 GB have their
capacity truncated to 8.6 GB upon Mount.
Image(s) Affected:
- [SYS$LDR]DKDRIVER.EXE
- [SYS$LDR]MKDRIVER.EXE
o On the CATAMOUNT (VAX 4000-90) platform, for systems that
allow up to 512MB of memory, PFN bits 18 and 19 are not mapped
properly, causing single-byte incorrect data to another page.
NOTE:
The PFN database is a portion of the nonpaged executive set
aside for accounting data. These memory management data
structures include information about the available pages of
physical memory.
Image(s) Affected:
- [SYS$LDR]PKBDRIVER.EXE
- [SYS$LDR]PKCDRIVER.EXE
- [SYS$LDR]PKRDRIVER.EXE
o A system crash occurs with an INCONSTATE bugcheck at
PKBDRIVER+298C. Also, the disk with a high error rate may end
up with incorrect data.
Image(s) Affected:
- [SYS$LDR]PKBDRIVER.EXE
- [SYS$LDR]PKCDRIVER.EXE
Problems addressed in VAXSCSI01_071 kit:
o Running HSZ10$STARTUP.COM (the startup file for the Raid110 box)
can hang and not complete. Running SYS$ETC:SCSI_INFO would also
cause a hang condition to occur.
o An attempt to initialize an RX26 floppy device fails with MEDOFL
if a previously uninitialized floppy is used.
o Sending an illegal IO$_AUDIO function to DKDRIVER can result in
a system crash, from user mode and without privilege.
o Fatal drive error during attempt to INIT the Exabyte 8200 tape
drive.
o An INVEXCEPTN bugcheck can occur in DEQUE_DEV_IO if a disconnected
command times out while a Request Sense is taking place.
o Under certain circumstances, targets can go into mount verification
without any error being logged into the errorlog.
o If a WFIKPCH times out instruction, stream code bits are modified.
Later, attempts to execute this modified instruction stream causes
system crashes and other problems.
o An attempt to initialize a tape device fails with DRVERR if the
tape drive disconnects during a Mode Sense command.
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.
