ABOUT THIS DOCUMENT
This document gives a brief description of each APAR that has a
fix included in the SelectPak IP07001 for OS/2 LAN Server 3.0
Server/Requester, UPM, Fault Tolerance, and RIPL.
LAN SERVER
The following list describes APARs for the Server component that
are fixed by this Service Pak.
* IC04302
Users receive SYS0008 (out of memory) messages when trying to
perform operations (for example, DIR X&colon.) on remote
drives. The following message is also logged.
NET3186E: The 386 HPFS Server ran out of the
following resource: 64KB Work Buffers
* IC04424
A trap 0 occurs in the Ring 3 server (NETSERVR.EXE) when the
requester sends an SMB read command with the number of read
bytes set to 0.
* IC04430
A trap often occurs in the 386 HPFS server when using
Microsoft** Windows 3.1 clients with the server.
* IC04431
The system traps because the Ring 3 server fails to release
space that has been allocated for renaming or moving files
with access control profiles.
* IC04710
Requirement to improve performance in deleting subdirectories
and in handling lock requests at the server. Some
applications also receive ERROR_LOCK_VIOLATION error messages
that end processing prematurely.
* IC04769
The server receives an error return code when trying to open
a shared COM port and does not set the device to error
status. The result is that all incoming requests are queued
up for the port. The device is left in an open condition
when viewed with the NET DEVICE command and cannot be cleared

or reset.
* IC04943
A trap occurs in the 386 HPFS server after installing NVDM/2.
* IC04973
If a DOS LAN Requester workstation performs a DIR command on
an empty directory, no volume label information is returned.
* IC04992
A trap 003 occurs when remote IPLing a client with an XGA
display.
* IC05010
HFS0102 messages display while running the CHKDSK command,
especially on larger drives (for example, 1GB).
* IC05058
A trap occurs in the 386 HPFS server when starting from
either a boot partition or boot diskettes. This problem may
occur on machines that previously ran with DBCS code pages
using OS/2 1.2 or OS/2 1.3.
* IC05073
A trap occurs in the 386 HPFS server when doing a hotfix on
an already hot-fixed sector. This problem usually occurs
when a drive fails (especially on a machine with an IBM 3515
disk subsystem).
* IC05075
Excessive access-denied violations accumulate in the server
statistics, causing alerts to be sent.
The permission violations in the server statistics do not
match the audit entries in the audit log. This may cause
confusion for users who have auditing enabled and get alerts
indicating permission violations but when the audit log is
viewed, there are no audit entries.
* IC05106
The 386 HPFS server returns a return code of 0 when doing a
DosCopy and duplicate files are encountered.
* IC05112
A trap occurs in the 386 HPFS server when TRACE code 154 is
enabled and the server tries to break an Oplock on a file.
Setting TRACE=ON or TRACE=ON 154 (when using SPM/2) could

cause the problem.
* IC05129
A trap occurs in the 386 HPFS server when trying to write to
a file that has become extremely fragmented. This requires a
file of at least 240KB in size, but happens more frequently
with larger files.
* IC05141
The last update time for a 386 HPFS file is being updated in
a DosOpen DosRead, DosBufReset combination.
* IC05182
A trap occurs in the 386 HPFS server (or in the OS/2 kernel)
during paging when 386 HPFS is handling paging and the page
file (SWAPPER.DAT) becomes fragmented.
* IC05184
Include MAKEDISK updates that will handle out-of-disk-space
errors when trying to build boot diskettes. This will also
verify that UHPFS.DLL exists on the boot diskettes so that
AUTOCHECK can be run.
Note: When building boot diskettes for OS/2 2.1, delete
A&colon.BUNDLE from backup diskette 1 before running
MAKEDISK.
* IC05188
Possible deadlock condition occurs when multiple programs try
to read uninitialized file data simultaneously from the same
file.
* IC05190
The 386 HPFS server returns an ERROR_FILE_NOT_FOUND message
instead of an ERROR_ACCESS_DENIED message when trying to
delete a directory using DosDelete.
* IC05200
A trap occurs in the 386 HPFS server when trying to set
attributes on a directory whose sector is not accessible
because of disk read/write errors.
* IC05240
A trap occurs in the 386 HPFS server when using the
Replicator service to import to a 386 HPFS drive.
* IC05256
About This Document 3
The 386 HPFS server will not correctly release space when the
page file (SWAPPER.DAT) size is decreased by OS/2.
* IC05327
Improve performance for servers running LAN Server for
Macintosh**.
* Additional fix without APAR&colon.
OS/2 LAN Server is unable to run with Ungermann-Bass**
NETBIOS transport code.
LAN REQUESTER
The following list describes APARs for the Requester component
that are fixed by this Service Pak.
* IC04248
Applications using a remote named pipe hang.
* IC04475
Programs cannot edit hidden files on a PCLP server.
* IC04492
An XCOPY of multiple files with an extension of .CMD or .BAT
fails. On the server, the NET ERROR log shows MAXSESSOPENS
exhausted.
* IC04532
Programs using the NETBIOSSUBMIT application interface may
hang.
* IC04600
The LAN Management Utilities/2 (LMU/2) product or other
programs that use DOSMAKEMAILSLOT() may fail with return code
87.
* IC04667
A NET3190 error displays the following message:
MSG incomplete in redir NCB 0600
Another symptom is that data is damaged on the requester.
These symptoms can appear when the requester accesses large
files or programs from the server.

* IC04697
A trap 0D screen displays with an unrecoverable system abend.
* IC04698
A page fault (Trap 0E) occurs when shutting down or rebooting
a remote IPL client.
* IC04750
A trap 0D screen shows EIP=00000032.
* IC04761
A 32-bit GREP program and other programs using the 32-bit
DOSFINDFIRST() DOSCALL may hang.
* IC04834
Programs running on a requester receive errors on file
operations (copying files, reading files, writing files). If
errors disappear when you set bits 9 and 23 to 0 in the
WRKHEURISTICS parameter in IBMLAN.INI, you are likely to need
this fix.
* IC04865
A remote IPL client hangs or stops with trap 8. In the case
of the hang, after the machine is rebooted, there should be
some entry in the NET ERROR logs stating that some resource
has been exhausted (for example, NUMWORKBUFS, MAXCMDS, or
MAXTHREADS).
* IC04963
A trap 0D occurs on the requester when the server uses a FAT
file system.
* IC05170
This is a workaround for a Microsoft Windows for Workgroup
problem. A copy from the IBM OS/2 LAN Requester to a Windows
for Workgroup machine can fail. The OS/2 requester was
changed to avoid encountering this problem. This APAR also
included a fix for updating the date and time of files stored
on OS/2 LAN Servers that were modified by Lotus 1-2-3**.
Another customer reported a different symptom. The 16-bit
DOSSETPATHINFO() call for a remote file on a server running
OS/2 2.0 or later could receive error code 87.
* IC05275
A damaged NETBIOS table causes programs using NETBIOS to
receive error 0x13.
About This Document 5
* IC05298
Logon is unsuccessful after a SPM/2 program is started, or
after other programs which use remote path names are started.
* Other fixes&colon.
- OS/2 LAN Requester is unable to run with Ungermann-Bass**
NETBIOS transport code.
FAULT TOLERANCE
The following list describes APARs for the Fault Tolerance
component that are fixed by this Service Pak.
* IC04815, IC04824, IC05414
Provide Fault Tolerance support for large disks having more
than 1.2GB or more than 1024 cylinders. If a mirror
partition has already been created, use FDISK to remove all
partitions on the disk. Then use FTSETUP or FTREMOTE to
remirror the drives.
* IC05409
Support for hot-replaceable disks. When a failed disk is
replaced without booting, this fix enables the Verify
function to restore the data from the good partition to the
replaced partition.
* Defect 1652
A trap occurs when mirroring a drive with FTSETUP or FTREMOTE
if the target disk containing the mirror partition has
damaged sectors.
* Modification to DISKFT.SYS
This fix makes it possible to install the Service Pak on a
mirrored drive. Refer to the installation instructions in
this document for information on installing the Service Pak
on a mirrored drive.

RIPL
The following APAR deals with RIPL Support for LS 3.0.
* IC05198
OS/2 2.1 implements several system changes that require
significant changes to the LAN Server Remote IPL service.
There is a section that describes how to update the remote
IPL client definitions for different display types and how to
support multiple versions of the OS/2 operating system in the
remote IPL directory structure.
This is new function introduced as a result of APAR IC05198.
For more detailed information regarding RIPL refer to the
IP07001.INF file that is included in the IP07001 ServicePak.
