TITLE: OpenVMS VMS721H1_SHADOWING-V0500 ALPHA V7.2-1H1 SHADOWING ECO Summary
New Kit Date: 24-JAN-2002
Modification Date: Not Applicable
Modification Type: Updated Kit Supersedes VMS721H1_SHADOWING-V0400
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-dcx_axpexe.pcsi, then it can
be expanded by typing RUN kitname-dcx_axpexe.pcsi. The resultant
file will be the PCSI installation file which can be used to install
the ECO.

ECO KIT SUMMARY:
An ECO kit exists for Shadowing on OpenVMS Alpha V7.2-1H1. This kit
addresses the following problems:
PROBLEMS ADDRESSED IN VMS721H1_SHADOWING-V0500 KIT:
o A system can experience many MountVerifcation messages occur
with no apparent cause and no errors reported. There is no
way to identify what is causing these messages
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o In a multi-node cluster, some cluster members may hang when
accessing a shadowset if:
o The shadowset being accessed has multiple members.
o All the shadowset members are local to one of the cluster
nodes.
o All the shadowset members are being MSCP-served by the
local node to the other cluster members.
o The local node goes down and remains down for at least
MVTIMEOUT seconds.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o On multiple member shadow sets greater than 18 Gigabyte in
size, if the port driver returns an SS$_DATACHECK for a
IO$_WRITEPBLK, the wrong LBNs will be written by the shadowing
driver. This could lead to data corruption.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o On a stand alone system, when a virtual unit aborts, the
system could crash with an INVEXCEPTN bugcheck.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o OPCOM will frequently display a virtual unit device, or the
member device string, without any other message. This can be
seen during startup if you are using a shadowed system disk,
or even during the dismount of the virtual unit or the
dismount of members.
This has been corrected so that you now will receive a
complete VMS message, such as:
%SHADOW-I-VOLPROC, DSA719: shadow master has changed.
Dump file WILL be written if system crashes.
rather than just displaying:
DSA719:
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
PROBLEMS ADDRESSED IN VMS721H1_SHADOWING-V0400 KIT:
o A system crash with an INVEXCEPTN SYS$SHDRIVER+7889 running
CTM_HIGH_IO can occur.
Crashdump Summary Information:
------------------------------
Bugcheck Type: INVEXCEPTN, Exception while above ASTDEL
Current Process: NULL
Current Image: <not available>
Failing PC: FFFFFFFF.804AE890 SYS$SHDRIVER+78890
Failing PS: 1C000000.00000804
Module: SYS$SHDRIVER
(Link Date/Time: 21-OCT-2000 03:11:44.71)
Offset: 00078890
Images Affected: [SYS$LDR]SYS$PLUSSHDRIVER.EXE
o If a second shadowset member is added, with a /POL=MINI
command, while another member is doing a mini copy, a
SS$_IVADDR crash can occur.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
[SYS$LDR]SYS$PLUS_SHDRIVER.EXE
o An 'Operation incomplete" error can cause a host-based raidset
to hang.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o A SHADDETINCON bugcheck occurs in routine SHLK$MERGE_SIGNAL.
Crashdump Summary Information:
------------------------------
Bugcheck Type: SHADDETINCON, SHADOWING detects inconsistent
state
Current Process: CTM$_00060006
Current Image: [CTM_HAMMER]CTM_HAMMER_ALPHA_32.EXE

(Link Date/Time: 15-DEC-2000 15:08:57.95)
Offset: 00093CD4
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o Mini copy operation abort with a %SYSTEM-F-IVADDR bugcheck.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o Fibrechannel devices cannot execute write logging Phase I. A
benchmark on GS series systems was consuming needless cycles
issuing TQEs that serve no purpose.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o A crash occurs with SHADDETINCON in SYS$SHDRIVER + 000762A0.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
[SYS$LDR]SYS$PLUS_SHDRIVER.EXE
o If the device is unable to perform a read SCB, the
/POLICY=MINICOPY command will fail.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o During a mini copy operation, the path to a shadow set member
may be switched before the SCB can be read. This causes the
operation to fail.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
[SYS$LDR]SYS$PLUS_SHDRIVER.EXE
o Multiple systems may hang on cluster shutdown because a
deadlock occurs when the WATCHER node closes.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o Multiple systems may hang on cluster shutdown because a
deadlock occurs when the WATCHER node closes.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
o A SHADDETINCON crash occurs in EXPEL_DEVICE.

master member is identified in an IN_SET lock value block is
not a member of the set on the Watcher node.
Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE
INSTALLATION NOTES:
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.
INSTALLATION INSTRUCTIONS:
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 VMS721H1_SHADOWING /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
SPECIAL INSTALLATION INSTRUCTIONS:
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:
- $ DEFINE/SYS NO_ASK$BACKUP TRUE
- $ DEFINE/SYS NO_ASK$REBOOT TRUE
- $ DEFINE/SYS USE_PLUS [TRUE,FALSE]
Note:
Defining the logical USE_PLUS as TRUE will install the
enhanced functionality Volume Shadowing driver image.
Defining the logical USE_PLUS as FALSE will install the
standard Volume Shadowing driver.
- Add the following qualifiers to the PRODUCT INSTALL
command and add that command to the DCL procedure.
/PROD=DEC/BASE=AXPVMS/VER=V5.0
- De-assign the logicals assigned
For example, a sample command file to install the
VMS721H1_SHADOWING-V0500 kit would be:
$
$ DEFINE/SYS NO_ASK$BACKUP TRUE
$ DEFINE/SYS NO_ASK$REBOOT TRUE
$ DEFINE/SYS USE_PLUS TRUE
$!
$ PROD INSTALL VMS721H1_SHADOWING/PROD=DEC/BASE=AXPVMS/VER=V5.0
$!
$ DEASSIGN/SYS NO_ASK$BACKUP
$ DEASSIGN/SYS NO_ASK$REBOOT
$ DEASSIGN/SYS USE_PLUS
$!
$ exit
