Hye everybody, There is a field named "DRAWER_IUID" in the OA$DATA_SHARE:PARTITION.DAT file. Is it use really by ALL-IN-1? This field contains the hardcoded hardware disk name, what's happend if the harware disk name is changed(For example backup disk)? Thanks for your help. Rgs, Thierry

Hi, I think the disk name is used to create a unique id. The id is never used in reverse to get the disk name, so it doesn't matter if the disk name changes. Scott | |||||

The IUID in the partition file is built and used by the FCS it is
returned to IOS or TeamLinks when they ask for it. They should never
be using it or storing it.
An IUID is guarneteed to be good for the life of a session to the FCS
(built when ever you access remote drawers or non-MAIN drawers), once
this session is taken down (exit ALL-IN-1) then the FCS does not
guarentee that the IUID would still be valid during your next session.
The IUID field in the partition file contains the device and file id
of a drawer. It is ok if this gets out of synch with reality since this
can happen. Steps have been taken to ensure that when this gets out
of synch it will be quickly repaired. We can do this on the fly and
also as part of our systme managment which FCVR calls.
Changing the disk name will not have a bad effect on you. It will
SLIGHTLY slow down the first drawer access, but you probably won't
even notice that.
