A PMR has been opened to report this VMLINK problem. I will be opening a n APAR. In the meantime, I have placed a R540 fixtest out on the IBM FTP s ite (testcase.software.ibm.com/fromibm/vm): VMLINK CEX76434 (compiled EXEC) a nd VMLINK SXE76434 (non-compiled EXEC). The fixtest should remain on

Ah, but while that was true of a ³real² 3390, is that also now true of emulated 3390¹s which are split across varying numbers of essentially SCSI disks? A single 3390 mod 27 might be split up over several 9 gig physical disks in order to implement the emulation. Is the controller smart enough to

But just to push things a bit further, isn't PAV the key to getting into the rat's nest successfully? If a volume has PAV aliases, then CP can start more than one I/O on the volume at a time. And, if it is sufficiently broken into smaller minidisks, then Linux can take advantage of the PAV paths

If it violates UArk rules, shouldn't you take the post off the archive? ( Yes, it is still here.) That would perhaps discourage people from posting job openings here. Am I the only one that reads this list at http://listserv.uark.edu/archi ves/ibmvm.html? Alan Ackerman alan (dot) ackerman
