Hi,
Do you maybe use different types of SFPs (longwave/shortwave) on both hardware-units (z10 and FC-Switch or storage system)? Do you use the corresponding cable to your SFPs? Or maybe you need to define which speed (2/4/8...) the channels of your storage system should use to communicate (instead of using 'auto)? Just the simplest thoughts at first...

Mai 2011 13:52 An: IBMVM@LISTSERV.UARK.EDU Betreff: Using EMC Clariion SCSI disk with Linux I posted this on IBM-MAIN with not much response so hoping someone on z/VM might be able to help. Opened a PMR with IBM software but they feel it is a hardware issue. Waiting for information on switch before contacting IBM hardware folks... We have a z10 in which I have defined 2 FCP chpids on our FICON Express8 cards. These chpids have NPIV enabled and I have provided the open system team with the WWPN's that were generated. The FCP chpids are dedicated to our 1 Linux IFL. We have connected the fiber, but the chpid, while staying ONLINE, gets a SEQUENCE TIME-OUT on the HMC. The light is on on the mainframe side, but not on the switch. The open system team tells me that there is nothing for them to do on their side until they can "see" the mainframe (light comes on?). In z/VM, the chips appear fine, defined as FCP with devices attached and FREE. I'm not sure what else I can do from the mainframe side to help the situation? I am not involved in the Linux portion but the Linux guy says he can't "see" the luns from Linux. Both sides appear to be waiting on me to fix things! The SCSI is a "CLARiiON CX-700 with FLARE (operating system) version 26 revision 31 (02.26.700.5.031) which is the latest release for the CX-700 product line. "
