9.2.3 Checking the Usage of the HDD/SSD

9.2.3 Checking the Usage of the HDD/SSD
To check the usage of the HDD/SSD, log in to Oracle Solaris.
This section describes how to check the configuration information for both the ZFS mirror volumes and the RAID volumes using the hardware RAID function of the SPARC M12 server.
For details on the commands for checking the ZFS volumes, see the document concerning ZFS file system management applicable to your Oracle Solaris version. To check the hardware RAID volume, use the sas2ircu command of the SAS2IRCU utility. For details on how to obtain the SAS2IRCU utility and the user guide, see "Obtaining SAS-2 Integrated RAID Configuration Utility" in the latest version of the Fujitsu SPARC M12 Product Notes.
Checking ZFS mirror volumes
