Re: UDFS File System on iSeries for IFS Storage

[Vern Hamberg <vhamberg@xxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi, Richard

A UDFS is the only way to get IFS files into another ASP. The root is 
always ASP 1. So that's one reason.

I can also see advantages if you have varying search paths, with a mounting 
point for the UDFS in each, so you'd unmount from one and mount to the 
other. Maybe   ;-)

I don't think a UDFS is accessible until you mount it. Could be wrong. It's 
a *BLKSF (block special file). I mounted one and put an obect into it at 
the mount point. The attributes of the *BLKSF did not change.

Make any sense?
