5.1.9 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
information.
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.
Capacity Cylinder Head Sector
< 64 GB variable 64 32
64 - 128 GB variable 64 64
128 – 256 GB variable 127 64
256 – 512 GB variable 127 127
512 GB - 1 TB variable 255 127

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:
