Hi,

Please let me know how to check the tape, how many times it is
reclaimed in
TSM.

The "Write Pass Number" reported in Query Volume is basically it, for
as long as the volume has been in the TSM library.  (Other things,
like incidental expiration of all data on the volume or Delete Volume,
can cause re-use.)  Otherwise, process your Activity Log for ANR1040I
entries.

And how many times can we use a LTO Gen3 and LTO Gen4 Media??

As Henrik has pointed out, you can find *general* recommendations in
vendor specs.  Another such source is cartridge spec sheets such as
