Hi ADSM gurus!

Is it posible to predict which tapes will be mounted during restore
operation ?
( I need to make a list of tapes,to bring the tapes from the secure offsite
archive,and
load them into 3494 library)
Currently ,the only way is to set library mountwait to 1 sec,run the ADSM
restore script
file by file and watch in the actlog for the tape mount requests.  It is a
_very_ slow way and this
has a serios impact to the library (3494) operation and can cause some
backup to fail
during this operation. Btw,it seems that if file is split between two tapes
error log will show
me only the first tape.
This way is ok if I need to restore a few files. But if I have a several
thousands of files ,archived
for several years,few thousands of tapes stored partially in the library and
partially offsite
this is a nightmare. ADSM must keep the information where the files are
stored
somewhere in his internal database,isn't it ? I simply *could* *not*
*believe* that there are no
smarter and easier way like to predict which tapes is necessary for restore.
Please answer me - is it possible or not ?

P.S. If the q content could display not only a filename ,but also an arhive
description,it could be
a solution. Unfortunately it can't do this.
