NAME

     chs - IBM ServeRAID PCI host adapter driver

DESCRIPTION

     The chs driver is the IBM ServeRAID PCI controller driver.

PRECONFIGURATION

  Known Problems and Limitations
     To prevent data loss, a SCSI disk drive that is not  defined
     as part of any physical pack within a logical drive will not
     be accessible through the Solaris operating environment.

CONFIGURATION

     Auto-configuration code determines whether  the  adapter  is
     present  at the configured address and what types of devices
     are attached to it. The IBM ServeRAID is primarily used as a
     disk array (system drive) controller.

     To configure the attached disk arrays,  you  must  configure
     the  controller  (using the configuration utilities provided
     by the hardware manufacturer)  before  booting  the  Solaris
     operating environment You use the configuration utilities to
     set RAID levels, stripe  parameters,  cache  mechanisms  and
     perform  other functions. For more information, see the user
     manual supplied with your hardware.
