Depends on the situation. I sysadmin about 100 zLinux LPARs (and about 300 zLinux zVM VMs). This is a development environment. not production, and very dynamic. All of the LPARs have access to all of the DASD. When the users of an LPAR run out of space, and need more, and are half-way around the world, and my phone goes off at 1am, I can be back in bed at 1:30 am, and not have to involve the "HW people": and not have to make the user wait until the weekend (AT BEST, if a new IODEF was required) to get their space.
Yes, a REALLY dumb user could bork another system. I've got them trained to open a ticket to me. for stuff like this.

The installer will let you select and format them. They need to get the i/o gen right. Marcy This message may contain confidential and/or privileged information.

Yes, this situation is exactly why cio_ignore was invented. You'll need to tell the kernel to ignore everything except the 2 DASD volumes, the 3 network device numbers, the console, and any other devices you know you're going to need. See the IBM page at http://www.ibm.com/developerworks/linux/linux390/documentation_suse.html and look "Device Drivers, Features, and Commands on SUSE Linux Enterprise Server 11 SP2 - SC34-2595-02 ".
