Here are the tested path-selector init patches. Basically, this type of function is need so devices like IBM's fastt can perform a manual failover. And, manual failover is useful for some types of clustering setups. These patches were built and tested against 2.6.6-udm1. 01-ps-refcount.patch - fixes the refcounting on the path-selectors. And, exports the register/unregister functions. 02-mv-path-code-to-ps.patch - some path-selectors will want to choose paths that have a couple of failed IOs vs always failing paths with X number of failures. Also some path-selectors will want to select a path by detecting congestion or some other determination than X bios have been sent. 03-ps-init-fn.patch - this adds the ps-init function. ps-manual-failover-exp.patch - this is just an exmaple of how you could use the init function. Please do not apply it. It was written based on some other patches, and I am trying to make it more generic so we can support other HW. I am only sending it becuase I am not sure if the functions I am using to send the failover command are correct and I am looking for feedback. -- Mike Christie mikenc@xxxxxxxxxx
