Question: We have gotten SAN (FCP) working with a couple of z/Linux Servers.
Right now we have: CHPID PATH=(98),PARTITION=((VMP1)),TYPE=FCP CNTLUNIT CUNUMBER=A800,PATH=(98),UNIT=FCP IODEVICE ADDRESS=(A800),CUNUMBR=(A800),UNIT=FCP CHPID PATH=(99),PARTITION=((VMP1)),TYPE=FCP CNTLUNIT CUNUMBER=A801,PATH=(99),UNIT=FCP IODEVICE ADDRESS=(A801),CUNUMBR=(A801),UNIT=FCP We attach A800 and A801 to the z/LINUX machine and everything works just fine. Now we want to have multiple SAN disks on the same Channels (CHPID 98 and CHPID 99) CHPID PATH=(98),PARTITION=((VMP1)),TYPE=FCP CNTLUNIT CUNUMBER=A800,PATH=(98),UNIT=FCP IODEVICE ADDRESS=(A800,64),CUNUMBR=(A800),UNIT=FCP CHPID PATH=(99),PARTITION=((VMP1)),TYPE=FCP CNTLUNIT CUNUMBER=A900,PATH=(99),UNIT=FCP IODEVICE ADDRESS=(A900,64),CUNUMBR=(A900),UNIT=FCP So we have 64 devices on Channel 98 and 64 devices on Channel 99. My question is this? If on the SAN side , if they define a disk on PATH 98 , do ALL of the 64 address defined in the IODF see the WWPN/LUN? (Or on a specific Port that equates to PATH/CHPID 98 on the on the mainframe side) If we have 8 zLinux servers defined under z/VM , we would need 8 separate device address (one for each z/LINUX) to gain access to that SAN / Path. I haven't been able to find a lot of documentation on this... They just give you the IODF definition and not a whole lot of explination on the details on HOW (if any) the device addresses work with the SAN (WWPN/LUN) We have been able to get a WWPN/LUN combination working on the SAN (PATH 98 and PATH 99). Just looking for some help from some people that have setup SAN disks attached to z/LINUX (not EDEV's). Thanks again in advance!
