In an attempt to negate the mount time issue in the restore process I am
currenlty using "move nodedata" to co-locate data for some of our
servers . Currently, our main file server has data on over 200 3590
tapes therefore a directroy restore can potentially have hours added to
the process directly related to tape mounts.

back to the point......


Does any know the what method is used in determining which media within
a storage pool is mounted first.

For example, is it;
- tape last write date, ie oldest tape first
- newest data first (active files) and all other data on that media is
moved
- biggest file then all other data on the media is moved.


Why do I want to know?

To experdite the process, where possible,  I read from multiple tapes
onto our disk pool and then drain the pool to a single tape. The problem
is the disk storage is not large enough or I have to cancel the process
prior the night process being impacted.

Therefore, I need to know what is being moved next time I run the
process. Am I moving the same data again or will a subsequent execution
of the command basically start where I left off
