Hi Mauro,

We found that RECLAMATION was also inadequate, so we created a our own
reclamation process using scripts to find volumes with the least usage and
reclaim them using MOVE DATA. This is executed from cron during low usage
periods.

Subject:  Reclamation takes ages




Dear(s),

        I'm running ADSM on a NSM-3466 with "Magstar MP" drivers ...
everything
fine with latest release (3.1.1.5), but the reclamation of a single
cassette can take up to 12 hours (!!), and this, with a reclamation
threshold set to 90%.

        I have the feeling that something funny is happening with the
cassette
movements, because the CPU is not used at all (sar -u). This is becoming
a nuisance because my library has only three drives and two are now
permanently busy doing nearly nothing ...

        Is anybody experiencing the same problem?


Thank you
