Configuring Disks

This section describes disk configuration tasks such as formatting, labeling, or partitioning disks. Disks are typically formatted and configured by the manufacturers and these default configurations are generally sufficient. However, you might need to perform some disk configuration in circumstances such as disk corruption and recovery.


Caution  -  Formatting a disk destroys existing data on the disk, and relabeling removes existing partition information. Make sure to perform the necessary backups to ensure that no data loss occurs if you reconfigure a disk.

The procedures to configure disks on both SPARC based and x86 based systems are similar. However, with x86 based systems, you use the fdisk option of the Format utility for disk operations.

To configure a disk, the disk must be inactive. Thus, if the disk to be configured contains Oracle Solaris, then you must boot from a different media. For more information about booting Oracle Solaris systems, see the topics on booting from a local media or from the network in Booting and Shutting Down Oracle Solaris 11.4 Systems.
