Preparing for Logical Drives Larger Than 253 Gbyte on Systems Running Solaris

The Solaris OS requires drive geometry for various operations including newfs. In order for the appropriate drive geometry to be presented to the Solaris OS for logical drives larger than 253 Gbyte, you have to configure Host Cylinder/Head/Sector Mapping Configuration using the Firmware Application. Refer to the SANnet II Family RAID Firmware User's Guide for your array for information about accessing the firmware application.

  1. In the Firmware Application, choose view and edit Configuration parameters > Host Cylinder/Head/Sector Mapping Configuration > Sector Ranges - > Variable, and then choose Yes to confirm your choice.

  2. Choose Head Ranges and specify 64.

  3. Choose Cylinder Ranges and specify Variable

NOTE: Refer to your operating system documentation for limitations on device sizes.
