Is there any plan to include support for DPT PM1554U2/PM1564U3 i2o controllers in the next (7.0 ?) RH release? DPT support told me that it's possible that the next version of SuSE will include support for their i2o controllers. Until now we've used 2.2.14 + dpt driver v.1.10 (available on request, they have 1.09 on their site) and it works fine. The only problem being that their monitoring daemon (online array operations) sometime consumes much cpu power for 1 or 2 seconds when you run the "dptutil" command line utility (but you don't have to use it if all works ok...). We haven't tested their X dptmanager. I see that there is the new i2o code in the official 2.2.x kernel (I read Alan Cox has tested DPT with it), but that is not enough for the DPT controllers and DPT monitoring daemon to work, at least this is what DPT told me, so you would need their driver. If there are no plans, is this because you would need to use their driver and you consider it not reliable or bad designed (it does not use the new standard i2o interface), or because RedHat thinks that there is not enough demand for DPT controllers support to justify the time needed for adding/testing the new driver? Thanks.
Im currently working with Adaptec (bought DPT) on this and aacraid stuff. The goal is to clean their driver up of problem header files (not their fault but i2o sig originated contamination) and get it into the mainstream kernel post 2.2.17 I have hardware from them and a driver to start cleanup on but it wont be for 2.2.17 or I suspect for 7.0
Thanks for the info. After I filed this bugzilla RFE, I found out about i2o sig problems in linux-kernel archives. I see now that my RFE should be updated since these days Adaptec/DPT is telling me that PM1564U3 will be out of production soon, and it will be replaced by Adaptec 2100s, made by DPT with an adaptec chip instead of qlogic one (buggy). "..The Adaptec 2100s and 3100s controllers (one and two channel respectively), are Ultra160 SCSI RAID Controllers. The controllers represent the next-generation of the DPT Decade Family of controllers. They feature Adaptec Silicon and the performance of these controllers will equal and in many cases exceed that promised by the Q-Logic-based DPT Decade controllers. ..." They say the linux drivers will be different. I hope they gave you these new controllers for testing :-))
Im marking this as DEFER for 7.1 era. Hopefully sorted by then
aacraid should be in something post 7.2. In the end I rewrote the aacraid driver. dpt_i2o is in current 2.4 now so should percolate everywhere fine.
