As KVM borrows the FCP support from Linux the answer is the same as for Linux in LPAR. In general the Linux code supports switched fabric and direct attachment. The code does not support arbitrated loop. What you also need is a support statement that tells about the storage server and the Z system. For example a V7000 DOES work when connected to a z Box (there is no fencing) but it is not a supported config (at least it was not when I check 3 years ago). So in general you are on the safe-side with a switch. Without a switch requires to check the certifications. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www2.marist.edu/htbin/wlvindex?LINUX-390
