If it looks like the others when you do a 'q v dasd' then it is a minidisk.
Most likely, it is a "near full pack" minidisk, which means it starts at cylinder 1 (and z/VM owns cylinder 0). Attaching it directly means that the guest sees the whole disk, including cyl 0. Linux will not know what to do with that. Attach the disk to SYSTEM. Then 'link owner oaddr myaddr mr' where "owner" is the virtual machine which owns the minidisk, "oaddr" is the address where it exists on the owning virtual machine, and "myaddr" is where you want it linked/attached/connected on the virtual machine where you want to fix it. (Pick any random address for "myaddr".) Then boot Linux, bring the disk online, and try fixing things. -- R; <>< On Mon, Aug 30, 2010 at 10:51, Daniel Tate <[email protected]> wrote: > Right on both accounts.
