System Overview

Click the Sun/Oracle logo in the upper left corner of the BUI to display a System Info pop-up window with information such as last updated date, serial number, and release.

Below the Sun/Oracle logo, the power icon presents a dialog box to either power off, reboot (power cycle), or reboot Oracle ZFS Storage Appliance with diagnostics.

Do not select the diagnostic reboot option unless Oracle Service personnel instruct you to select it. The diagnostic reboot can take a long time to complete and can have adverse results if not performed properly. Do not perform a diagnostic reboot when operations are occurring that affect the entire system, such as upgrading firmware, executing commands, or configuring or unconfiguring storage. The diagnostic reboot option is not available from the system chassis power icon.

The Maintenance: Hardware page shows a summary of the system chassis and any attached disk shelves (on supported systems).

System Chassis

The top half of the Maintenance: Hardware page shows the primary system chassis. The chassis name is initially set to the Oracle ZFS Storage Appliance name during installation. To change the chassis name, use the System Name field on the Configuration: Services: System Identity page. For more information, see System Identity Configuration in Oracle ZFS Storage Appliance Administration Guide, Release OS8.8.x.

To the left of the chassis name is an icon that indicates whether any components in the chassis are faulted. See the descriptions of status icons in BUI Hardware View. When you hover over the status icon, the icon becomes an information icon . Click the information icon to display a Component Details pop-up window for the chassis.

Do one of the following to display a new page with more detail about the chassis, as described in Chassis Details View:

Click the right-arrow icon to the left of the status indicator icon.
Click the chassis illustration to the left of the right-arrow icon.
Click the Show Details link below the illustration.

At the top right of the system chassis section is the locator icon . Click the locator icon to turn the chassis locator LED on or off. The icon flashes when the locator LED is on.

The power icon presents a dialog box to either power off or reboot (power cycle) the appliance.

The following table describes the information that is shown in this summary view.

Table 1-2 System Chassis Properties

Property	Description
Manufacturer	Manufacturer of the system
Model	System model name
Serial	System chassis hardware serial number
Processors	Count and description of processors in the system
Memory	Total memory in the system
System	Size and number of system disks used for the system image
Data	Size and number of data disks in the system chassis. This property is valid only for standalone systems. If no data disks are present, a hyphen character (`-`) is displayed.
Cache	Size and number of read-optimized cache devices in the system chassis. This property is valid only for expandable systems that support additional disk shelves. If no cache devices are installed in the system chassis, a hyphen character (`-`) is displayed.
Log	Size and number of log disks in the system chassis. This property is valid only for standalone systems. If no log devices are installed in the system chassis, a hyphen character (`-`) is displayed.
Total	Total size and count of all disks in the system

Disk Shelves

A list of disk shelves, if supported, is displayed below the system chassis section on the Maintenance: Hardware page. The illustration in the Disk Shelves section changes to represent the front of the disk shelf that is currently selected in the list.

Do one of the following to display a new page with more detail about that disk shelf, as described in Disk Shelf Details View:

Double-click an entry in the list.
Click the right-arrow icon at the far left of each entry in the list.

To the right of the right-arrow icon is an icon that indicates the status of that disk shelf. When you hover over an entry, the status icon becomes an information icon . Click the information icon to display a Component Details pop-up window for that disk shelf.

At the far right of each entry in the list is a locator icon . Click the locator icon to turn the locator LED for that disk shelf on or off. The icon flashes when the locator LED is on.

The following table describes the information that is shown in the entry for each disk shelf.

Table 1-3 Disk Shelf Properties

Property	Description
Name	Name of the disk shelf, used in faults and alerts. The name is initially set to the serial number of the disk shelf. To change the name, click on the name in the entry.
MFR/MODEL	The disk shelf manufacturer and the model number.
Type	Device type: HDD or SSD.
RPM	Disk revolutions per minute.
Data	Total size of all data disks within the disk shelf.
Cache	Total size of all read-optimized cache devices within the drive shelf. If there are no cache devices in the shelf, then a hyphen character (`-`) is displayed. Read cache devices are supported in DE2-24 disk shelves with a minimum software version. For software requirements and slot configuration rules, see Disk Shelf Configurations.
Log	Total size of all write-optimized cache devices within the drive shelf. If there are no log devices in the shelf, then a hyphen character (`-`) is displayed.
Paths	Total number of I/O paths to the disk shelf. This value normally should be 2 because only configurations with multiple paths to all disks are supported. Click the information icon to show each HBA slot and the state of each path. If the disks within the disk shelf are not currently configured as part of a storage pool, complete path information will not be available, though two paths to the chassis are displayed.
