CloudPools recall via file pool policy

[Previously posted on the TUG, but no responses there, so...]

Hi all,

We've just started using CloudPools to archive old data from our Isilon cluster to the cloud, to free up some space on the cluster.

However, what I've been unable to work out is if it's possible to use a file pool policy to recall files from the cloud.

So, if you have a file pool policy which says "Files in directory x/y/z with modification date older than 6 months ago, archive to CloudPool A", is it possible/necessary to have another policy which says "Files in directory x/y/z with modification date newer than 6 months ago, recall to Isilon"?

All I can find in the documentation is a statement that files can be fully recalled from the cloud with "isi cloud recall" (isi cloud archive recall with newer OneFS).

So, if you do want to bring back files in a policy-based manner, can this be done with SmartPools, or do we need to put in place cron jobs on the cluster which run "isi cloud recall"?

Cheers,

John
