Partitioning disk drives
Requirements for partitioning data disk drives differs for the releases of CMS.

R3V9 and later

If you are adding new disk drives to a system where CMS is operational, partitioning is
done automatically using CMS commands. Skip manual partitioning and continue with
Administering data disk driveson page 121.
If you are replacing a defective disk drive in a system and CMS is not operational or if you
are replacing a defective boot disk, you must manually partition the disk drive. Use the
following information:
●Disk partition values, R3V11 boot diskson page 112, R3V9 boot diskson page 112, or
R3V9 and later data disks on page 113
●Partitioning and formatting a disk on page 117

R3V8 and earlier

For R3V8 and earlier systems, you must partition and format the new or replacement disk
drives. Use the following information:
●Disk partition values, R3V8 and earlier data diskson page 115
●Partitioning and formatting a disk on page 117

Disk partition values

During the disk partitioning procedure, you must enter the size of each partition. Since disk
models change often, see the software installation, maintenance, and troubleshooting
document for your current CMS release to verify the correct disk partitioning values.
