Actually - you never want to do that regardless, unless using some kind of clustering file system... ?
The best way IMO is actually via SFS if you're talking z./VM -- or some kind of file sharing solution if on Linux (NFS export the disk, serve it via samba, ftp, etc). But the general answer is that the minidisk 'is' available to other guests (they can attempt a LINK user disk) - the question is whether they are authorized and will get the access. Authorization is either via minidisk password (not safe) or an ESM like RACF or VMSECURE. The problem with allowing multiple write access is that your students will have the ability to issue a link mode of MW and could get the disk in R/W even though another student has it in read/write and then corrupt the disk. As long as they know to use MR or M -- then their LINK would fail if it was already in R/W by another student which is what I'm guessing you want? Not a perfect solution but it works if those accessing the disk know the rules and respect them. Anyway -- giving us more detail about what you're trying to accomplish and what filesystems are involved, etc - would help us give specific advice.
