Just in case anyone believes that volume sets are difficult/dangerous/etc : all you have to do ( after initialising the disks ) is to issue the simple mount command $ MOUNT/SYS/BIND=name device1:,device2: label1,label2 After that you can refer to the set with 'name' or 'device1' and all operations and utilities appear to treat it as a single device. I haven't encountered any problems with any item of software so far : backup/restore/quotas,etc all work as well as on a single device. I'd recommend volume sets to anybody with enough disks to implement them. It greatly reduces the number of device,etc names users have to remember and you gradually expand existing logical devices simply by adding another volume to the set. John

Another wonderful feature of volume sets is that a head crash on any one drive effectively takes them all out of commission from the user's point of view! Then, once the problem is fixed, you have to restore the entire volume set from backup rather than just one disk drive! The more drives, the better, I say! So, yes, I'd recommend volume sets but only to my worst enemies!
