Dear Listers We are about to reconstruct a 959/400, replacing a "farm" of old and new disks with new disks in HASS enclosures. We have decided to use the internal disks (1 x 4GB and 3 x 9GB) as the System Volume, and make each of the four fully populated HASS's separate private volumes. The questions are:- Is there any problem foreseen (performance?) if we place the production accounts in their entirety on the HASS's? Also, what is the best way of achieving this? I have looked at BULDACCT.PUB.SYS, and I it looks very helpful. I think that we could :- store @[log in to unmask],@[log in to unmask]@[log in to unmask]@.sys;*t;directory make an SLT rebuild the machine install the system with the SLT restore *t;;directory restore *t;@[log in to unmask];keep;create;olddate use buldacct to reposition certain production accounts using fromvs and vsacct restore *t;@[log in to unmask]@[log in to unmask]@.sys;create;olddate fight with utilities and subsystems that require tweaking test until reasonably satisfied store @[log in to unmask],@[log in to unmask]@[log in to unmask]@.sys;*t;directory I know I must have missed something, but I'm hoping that if we hold our mouths just right and cross our fingers, we can achieve this. All help/hints greatly appreciated. Neil Harvey
