Single System Image is not in z/VM 6.1. It's a Statement of Direction, which means IBM intends to put it in a future release, but isn't promising anything.
Dennis "Of all tyrannies, a tyranny exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end, for they do so with the approval of their own conscience." -- C.S.

Larry Davis -----Original Message----- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Robert J McCarthy Sent: Monday, November 16, 2009 4:08 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Shared DASD across multiple VM lpars We have a growing VM/Linux environment with currently about 75 linux guests spread across three VM lpars. All DASD is defined as shared. All of the linux guests have been defined as TCPIP Layer 2; so that we can easily move guests between lpars for performance/maintenance reasons. Each guests has unique mini-disks for the linux 191 and DASD swap spaces. Is it advisable to share the full volumes that these mini-disks reside on, across VM lpars; assuming of course, that a linux guest is completely shutdown and logged off of one lpar before it is restarted on another ?
