Description of problem:
I need to connect my p5 server to HP Storagework EVA6000 via
device-mapper-multipath. I found a module called dm-hp-sw, but I'm not sure if
it is necessary for handling of I/O errors and path-group switching.  

Additional info:
Comment 1 Ben Marzinski 2007-09-04 14:26:29 EDT
No. The dm-hp-sw hardware-handler module is for active/passive storagework
arrays.  I believe that that EVA6000 is active/active, so no special kernel
module is necessary. device-mapper-multipath should autoconfigure for the EVA6000.
