    Creation of CCISS dev noded for Smart Array controller.


    I have SA E200i as embedded controller, SA E500 & SA P400 controllers attched to the machine with Red Hat 5.2.
    In /proc/devices, major numbers assigned for cciss controllers as
    104 cciss0
    105 cciss1
    106 cciss2
    But only one dev node c2d0 has created in the /dev/cciss.
    Since my application, reads these dev nodes & gets the infromation about SA controllers, it is failed to get about SA E500 & SA P400 controllers.

    Could you please tell me, when these dev nodes are created? And why it has not been cretaed for rest two of the controllers???

    Since c2d0 is the disk attached to that one controller, it would appear no disks are attached to the other controllers. So no /dev/cciss/c<X>d<y> is created because there is no disk/no need.

    I am *guessing* this might not be the best place to find controller info.

    But with same configuration, same machine with Red hat 5.1, these all controllers are displaying through my application.
    and c0d0,c1d0 & c2d0 dev nodes has been created under /dev/cciss.

    Could u please suggest the best place to find the controller info?

    There must have been a change between the versions then.

    You can A) read RedHat's release notes for 5.2 and/or B) read the documentation for the cciss driver.

    For controller info - lspci ?
