Hi all,
You should always disable RSM on Storage Nodes/Dedicated Storage
Nodes/Networker servers. Also you can disable the devices within RSM if you
decide to let RSM enabled. Watch out! when you are using non-persistent
bindings on your san attached library this will give problems!
My opinion always disable RSM!
Regards,
Erwin

Are you saying that the RSM should be disabled on W2K3 Networker servers and
W2K3 storage nodes?

Subject: [Networker] AW: [Networker] sudden change in tape capacity?
Hello dear fellow-networkers,
we faced the problem of premature marking tapes as full both with DLT8000
drives and with LTO2 drives for a couple of months. As the native capacity of
LTO2 tapes is 200 GB, you must know what it looks like when a 200 GB tape is
marked full at the capacity of !!! 0 kB !!!.
As the reason was is claimed by leading supporters and hardware experts of the
Siemens company that there happen undesired tape rewinds. As the block size at
the tape header differs from the block size of the data section after the
header, when Networker notices that it got a different block size it will mark
the tape as full and mark the savesets as suspect.
Maintaining networker storage nodes we had to disable the "Removable storage
Manager" of Win2k resp. Win2k3. The funny thing is that how Legato introduces
Networker 7.x it sounds like if Networker and the removable storage manager
would be "best friends".
Freundliche Grüße / Kind regards
Roman Böhm
