Hello Everybody,
I am testing TSM 6.1 under AIX.
I have tried to enable de-duplication for primary disk pool:
tsm: BKME>upd stg daily_1 dedup=y
ANR2344E UPDATE STGPOOL: The "DEDUPLICATE" option is not valid for device class
DISK.
ANS8001I Return code 3.
tsm: BKME>
I have been affected too much by this message, because most of our primary
pools are on FATA disks.
Could somebody explain me why IBM is not able to use de-duplication for device
class DISK?
What is behind this?
I understand I was reading all available before documentation not enough
carefully, because I was sure that it is much easier to de-duplicate data on
disks in comparison with tape drives.
Kindest regards,
