DualStor Internal Tape Backup Unit - SYS3175 error with DualStor for OS2
Applicable to: World-Wide
Products Involved:
44H3111 - DualStor 800 Internal Tape Backup Unit
44H3366 - DualStor Tape Backup Program v3 for OS/2
31H5622 - DualStor 800 Internal Tape Backup Kit for OS/2
Problem Description:
This patch is for users of DualStor for OS/2 who are receiving SYS 3175 errors when trying to open a session log. This patch should only be necessary if problems began after installing Warp Fixpack 17. The module on which the SYS3175 error occurs should be PMMERGE.DLL. There are 2 solutions.
Solution 1:
Download PMMDSLOG.ZIP, which unzips into PMMERGE.DLL and README.TXT (this document) and install PMMERGE.DLL.
Note: Do not power off or reboot your PC until the following instructions have been sucessfully completed and this document instructs you to do so.
Installation instructions:
1. Unzip the contents of PMMDSLOG.ZIP onto a floppy disk or a temporary directory on your hard drive. If you are reading this, you may have already done so.
2. Reboot (per the specifications immediately below)...
-If OS/2 resides on an HPFS partition: Boot off of the first two install disks to get to an OS/2 command prompt.
-If OS/2 resides on a FAT partition: Boot off of a bootable diskette (DOS or first two OS/2 install disks) or another partition if available.
3. Change to the OS2\DLL\ subdirectory on the drive or partition on which the failing version of OS/2 was installed and type:
COPY PMMERGE.DLL PMMERGE.IBM <Enter>
-The system should respond with a message noting that this command completed sucessfully (such as "1 file copied".)
-If this command did not complete sucessfully, do not continue.
4. To remove the old PMMERGE.DLL (which was copied to PMMERGE.IBM for archival purposes) type:
DEL PMMERGE.DLL <Enter>
5. Type:
COPY Drive:\PATH\PMMERGE.DLL <Enter>
Where Drive: is the drive on which the new PMMERGE.DLL exists, and PATH is the fully rooted path to the subdirectory containing PMMERGE.DLL.
Example one:
If you unzipped the contents of PMMDSLOG.ZIP onto a blank floppy diskette, insert that diskette into the diskette drive. For the purposes of this example, I will assume the diskette drive is A: (although it may be B: on your system). Type the following command (from the OS2\DLL\ subdirectory):
COPY A:\PMMERGE.DLL <Enter>
Example two:
If you unzipped the contents of PMMDSLOG.ZIP into a temporary directory called C:\TEMP, issue the following command (from the OS2\DLL\ subdirectory):
COPY C:\TEMP\PMMERGE.DLL <Enter>
6. You may now reboot your system into OS/2 and test to see if you can open a DualStor session log without receiving a SYS3175 error on PMMERGE.DLL.
7. If you no longer receive an error message, you are done. You can remove this README.TXT and PMMERGE.DLL from the temporary directory or floppy disk if you so desire.
8. If you still receive an error message, you can either keep the existing PMMERGE.DLL or restore the old one. If you encounter new problems with your system using the new PMMERGE.DLL, you may want to use the older one instead.
To restore the old PMMERGE.DLL:
1. If your OS/2 system resides on an HPFS partition, boot off of your first two OS/2 install disks. Otherwise, boot to another partition or from a bootable diskette (DOS or 1st two OS/2 install disks).
2. Change to the OS2\DLL\ subdirectory on the drive or partition which the failing OS/2 was installed on.
Note: Do not power off or reboot your PC until the following instructions have been sucessfully completed and this document instructs you to do so.
3. Type:
COPY PMMERGE.DLL PMMERGE.DSF <Enter>
This command should be confirmed with the system (such as "1 file copied"). If this command did not execute properly, do not continue.
4. Type:
ERASE PMMERGE.DLL <Enter>
COPY PMMERGE.IBM PMMERGE.DLL <Enter>
This should restore your old PMMERGE.DLL. You can reboot your machine and it should operate as it did before starting these instructions.
Solution 2:
If Solution 1 does not resolve the problem get the lastest version of DualStor. The latest version is 3.0b.
