Check the MOUNTLIMIT in the client definition.
It controls how many mount points in a sequential pool the client can use at 
once.

Subject: [ADSM-L] Deduplication Question
Importance: High

Hi All,



                I am testing Deduplication on a Red Hat 5 , 64 Bit, X86
Linux Server, using TSM Server version 6.2.2.2.   I set up a storage pool
for Deduplication and using a file devclass.  When I try to back up a windows 
client to the storage pool, I am getting an error that says "ANR0525W - Server 
Media mount not possible".  However, when I back up to a standard storage pool 
with a disk devclass, the same client backs up perfectly and then the data can 
be migrated to the deduplicated storage pool.  My questions are these:



1)      Can you back up a client directly to a deduplicated storage pool?
If so, how?

2)      What criteria should be used for the creation of volumes for a
deduplicated storage pool?

3)      Is there documentation that specifically says that you have to
migrate data to the deduplicated storage pool?





Any insight on these issues will be greatly appreciated!  Thanks!
