Heine,
I know there are several technotes on Veritas' support site that state
this problem and the proper method of disableing it on W2K media
servers. I have not gotten to W2K3 testing yet so I can't comment on how
it acts with a "client". I did come across this article on HP's website
and also have gotten some info from Microsoft. Hope this helps.

>From Microsoft:
The polling is done by tape driver. This is to help RSM identify media
changes, So I am not sure how disabling RSM stops the polling (unless
RSM disables polling temporarily, but fails to reenable it).
The actual 1-second-interval Test Unit Ready (TUR) is sent down by
classpnp.
A user mode app can turn this OFF by sending down the
IOCTL_STORAGE_MCN_CONTROL IOCTL to turn this off.
The customer can write a custom utility to turn this off if they don't
want to add the registry entries, the utility would then need to be
executed after every reboot, possibly by a start-up script.

ase/ioctl_storage_mcn_control.asp
To permanently disable the tape drivers from polling the bus they can
add a registry entry :
HKLM,"System\CurrentControlSet\Services\qic157","AutoRunAlwaysDisable",
0x00010008, "VEN_ID PROD_ID"
where VEN_ID is vendor id (and should be 8 chars long. If it is lesser
than 8 chars add trailing spaces", and PROD_ID is Product ID and 16
chars long (with trailing spaces).
Example:
HKLM,"System\CurrentControlSet\Services\qic157","AutoRunAlwaysDisable",
0x00010008, "WXYZ QIC157 "

Subject: [Veritas-bu] Removable Storage Management: unable to export
database
One of our clients always ends every backup job with the following
message:
17.03.2004 10:23:26 - Warning bpbrm(pid=2820) from client mailgw01: WRN
- Removable Storage Management: unable to export database (WIN32 21:
Unknown
error)
What does this "Removable Storage Management: unable to export database"
message mean? I can not find any documentation on this warning. Restore
seems to work well, and the job finishes with status 0. But still, a
message like that makes me a bit worried.
We are using Netbackup 5.0 on a Win 2000 Master/mediaserver. This
particular client is Win 2003 with Netbackup 5.0.
Thanks,
Heine Didriksen
Bergen, Norway
