ANR8466E  command: Invalid update request for drive drive name in
     library library name.

Explanation: An invalid update request has been made for the given
drive. This can occur if a new device name is given and the
characteristics of the device do not match the characteristics of the
original device.

System action: The server does not process the command.

User response: If a different type of drive has been installed, the old
drive definition must be deleted with a DELETE DRIVE operation, and a
new drive must be defined. The UPDATE DRIVE command cannot be used in
this case.


As it says in the error description, you must not only delete the drive
paths, but the drive definitions themselves. Deleting the drive path
does not remove the previous drives information, and when you try to
redifine the path, its expecting to connect to that old drive, which
obviously no longer exists.

Subject: [ADSM-L] define path problems

TSM server 5.3.4 on windows 2K server.

Overland Neo 4100 LTO2 library with 2 x LTO2 drives conected via SCSI
320.

We recently replaced both LTO2 drives in the library, as well as the
SCSI
HBA. The drives and library are fine in windows when running the HP
StorageWorks libray and tape tools.

Instead of updating the paths in TSM, I just deleted them. The devices
were NOT deleted, just the paths:

tsm: ITG-TSM>q drive

Library Name     Drive Name       Device Type     On-Line
------------     ------------     -----------     -------------------
LB6.0.0.5        MT1.0.0.4        LTO             Yes
LB6.0.0.5        MT2.0.0.4        LTO             Yes

So first I create the new path for the library and that works:

tsm: ITG-TSM>define path itg-tsm lb6.0.0.5 srctype=server
desttype=library
             device=lb6.0.0.4 online=yes
ANR1720I A path from ITG-TSM to LB6.0.0.5 has been defined.
tsm: ITG-TSM>q path
Source Name     Source Type     Destination     Destination     On-Line
                                Name            Type
-----------     -----------     -----------     -----------     -------
ITG-TSM         SERVER          LB6.0.0.5       LIBRARY         Yes


But when I try to add the drives paths, I get an error:

tsm: ITG-TSM>define path itg-tsm mt1.0.0.4 srctype=server desttype=drive
             library=lb6.0.0.5 device=mt1.0.0.4 online=yes
ANR8466E DEFINE PATH: Invalid update request for drive MT1.0.0.4 in
library
LB6.0.0.5.
ANS8001I Return code 15.


Any ideas? I'm kinda at a loss of what to try next, especially because I
had done this update path a while ago and it worked just fine.

Thanks,

Alex
