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 manu- facturer) 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. FILES
