Adding a Third-Party Disk
The Solaris OS supports many third-party disks. However, for the disk to be
recognized, you might need to supply either a device driver, a format.dat
entry, or both. Other options for adding disks are as follows:
If the third-party disk is designed to work with standard SunOS compatible device
drivers, then the creation of an appropriate format.dat entry should suffice to allow
the disk to be recognized by the format utility. In other cases, you
need to load a third-party device driver to support the disk.
Note - Sun cannot guarantee that its format utility will work properly with all third-party
disk drivers. If the disk driver is not compatible with the Solaris format
utility, the disk drive vendor should supply you with a custom disk formatting
This section discusses what to do if some of this software support
is missing. Typically, you discover that software support is missing when you invoke the
format utility and find that the disk type is not recognized.
Supply the missing software as described in this section. Then, refer to the
appropriate configuration procedure for adding system disks or secondary disks in Chapter 12, SPARC: Adding a Disk (Tasks) or
Chapter 13, x86: Adding a Disk (Tasks).
Creating a format.dat Entry
Unrecognized disks cannot be formatted without precise information about the disk's geometry and
operating parameters. This information is supplied in the /etc/format.dat file.
Note - SCSI-2 disks do not require a format.dat entry. The format utility automatically configures
the SCSI-2 drivers if the disks are powered on during a reconfiguration boot.
For step-by-step instructions on configuring a SCSI disk drive automatically, see How to Automatically Configure a SCSI Drive.
If your disk is unrecognized, use a text editor to create an
entry in format.dat for the disk. You need to gather all the
pertinent technical specifications about the disk and its controller before you start. This
information should have been provided with the disk. If not, contact the disk
manufacturer or your supplier.
How to Create a format.dat Entry
- Become superuser or assume an equivalent role.
- Make a copy of the /etc/format.dat file.
# cp /etc/format.dat /etc/format.dat.gen
- Modify the /etc/format.dat file to include an entry for the third-party disk.
Use the format.dat information that is described in Chapter 16, The format Utility (Reference).
Also, use the disk's hardware product documentation to gather the required information.
