8.1.9 Cylinder/Head/Sector Mapping
Drive capacity is decided by the number of blocks. For some operating systems (Sun Solaris,
for example) the capacity of a drive is determined by the cylinder/head/sector count. For Sun
Solaris, the cylinder cannot exceed 65535; choose "cylinder<65535,” then the controller will
automatically adjust the head/sector count for your OS to read the correct drive capacity.
Please refer to the related documents provided with your operating system for more informa-
tion.
Cylinder, Head, and Sector counts are selectable from the configuration menus shown below.
To avoid any difficulties with a Sun Solaris configuration, the values listed below can be
applied.
Older Solaris versions do not support drive capacities larger than 1 terabyte.
Solaris 10 now supports array capacity larger than 1TB. Set the values to the values listed in
the table below:
