YOu went wrong on the zfcp.conf configuration. you will notice that where you put in the 0x1: you need to have a 0x01 and where you put in the LUN # of 0x0: you need to have 0x00:, it is very picky. If you have one thing wrong it won't work. -Cameron

The question really revolves around redundancy. In most references to connecting an FCP device to Linux (we're running SuSE SLES8 on z/VM 5.1), they talk about connecting 1 FCP channel on VM, to 1 WWPN on a switch to multiple LUN's on the shark. In other words, something like this On VM ATTACH a210-a211 TO LINUX1 (Documentation suggested a QDIO pair of addresses) On Linux rmmod zfcp modprobe qdio modprobe scsi_mod insmod zfcp loglevel=0 map="\ 0xa210 0x1:0x5005076300d08276 0x0:0x502f000000000000" modprobe sd_mod With the key word mentioned above, "REDUNDANCY", is it possible/feasible to do the following? On VM ATTACH a210-a211 TO LINUX1 ATTACH a310-a311 TO LINUX1 On Linux rmmod zfcp modprobe qdio modprobe scsi_mod insmod zfcp loglevel=0 map="\ 0xa210 0x1:0x5005076300d08276 0x0:0x502f000000000000;\ 0xa210 0x2:0x5005076300c28276 0x0:0x502f000000000000;\ 0xa310 0x3:0x5005076300d08276 0x0:0x502f000000000000;\ 0xa310 0x4:0x5005076300c28276 0x0:0x502f000000000000" modprobe sd_mod Notice the 2 different WWPN's for the 2 different addresses (a210 and a310). Am I completely missing something here???
