Re: Domini on iSeries and UDFS

[Vernon Hamberg <vhamberg@xxxxxxxxxxx>]

UDFS is user-defined file system. You use CRTUDFS to create one. This 
creates what is called a block special file under /dev/QASPxx. Then you 
mount the UDFS on an existing directory in the IFS. You have several 
options, including case-sensitivity. Then use it just like anything else in 
the IFS - completely transparent.

This is the only way i know to put IFS objects into an ASP other than the 
system ASP. It is completely local. Of course, some storage devices (IBM 
DS6800, IIRC) can be attached to an iSeries and look just like local DASD. 
These could be put into ASP 2 or whatever. Then you could put a UDFS there, 
and anything you put in that location ends up on the storage device, not 
the internal DASD. Of course, I have heard that external storage from IBM 
is much more expensive than putting more disk in a sidecar. So it is not 
recommended to use external storage if the only machines that need it are 
iSeries.

As usual, look at the help in CRTUDFS and MOUNT. Do a GO CMDUDFS for 
starters, as well.
