Oracle Solaris OS Installation Overview

In order to successfully complete the installation, use an FC-based device during the disk selection portion of the installation. At the end of the interactive installation, you must change the x86 BIOS and FC HBA BIOS to identify the FC initiator that will be used to boot Oracle Solaris from a remote multipathed disk.

After OS installation and before rebooting, gather the configuration information by issuing the luxadm command on the newly installed logical unit number (LUN). The luxadm command output provides a map from c#t#d# to the array WWN and LUN. Record the HBA World Wide Name (WWN) and array WWN port information.

During rebooting, use the WWN and LUN to set the HBA BIOS for each HBA to be used to boot from each LUN on the same array. Change the system BIOS to perform booting from CD-ROM or Network to disk.

Note - Console access is required for HBA and system BIOS changes.

In addition, note the following during an Oracle Solaris OS installation:

  • If using a custom disk layout, do not remove the overlap (s2) partition. The x86 boot installer has a dependency on this partition.

  • By default, Solaris I/O multipathing features manage the FC boot devices with multiple paths to a single boot device.
