Locating a disk

Hardware View

The Maintenance > Hardware screen (also known as the "hardware view") provides component status of the appliance and attached disk shelves. This information is available from both the BUI and the CLI.

BUI

The BUI hardware view provides interactive illustrations that enable you to browse through the appliance and attached disk shelf components. The screenshot at the top of this page shows a disk highlighted in a Sun Storage 7110, showing both its physical location and details.

The buttons in the hardware view are:

icon	description	icon	description
	Show a more detailed view of this component		Toggle blinking of the locator LED for this component
	Leave this detailed view		Reboot the appliance
	Click for more details		Power off the appliance
	Hardware component is ok (green)		Offline disk
	Hardware component is not present (grey)		Port active
	Hardware component is faulted (amber)		Port inactive

System Overview

The main hardware page lists the system chassis, a summary of its contents, and any attached disk shelves (on supported systems). This provides an overview of the hardware present on the system, as well as controls to reset or power off the system.

System Chassis

The primary system chassis is shown on the top half of the view. At the top left, click the to get more detail about the chassis. The indicator notes if there are any faulted components within the chassis, and the name of the chassis. The chassis name is initially set to the appliance name during installation. To change the chassis name, use the entry field on the Configuration > Services > System Identity screen.

At the top right of the system chassis is the control to light the locate LED, reboot the appliance, and power off the chassis. Note that in configurations with attached storage and for the 7700 cabinet, the controller does not control the drive shelf power. The reboot and poweroff operations are identical to those provided at the left of the masthead.

A thumbnail of the controller is presented at left. Clicking on the thumbnail or the "Show Details" link takes you to a detailed view of the chassis, and is identical to clicking on the right pointing arrow at the top left of the view.

The following information is presented in a summary view:

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 is only valid for standalone systems. If there are no data disks present, "-" will be displayed.
Cache	Size and number of cache disks in the system chassis. This is only valid for expandable systems that support additional disk shelves. If there are no cache disks present, "-" will be displayed.
Log	Size and number of log disks in the system chassis. This is only valid for standalone systems. If there are no log devices present, "-" will be displayed.
Total	Total size and count of all disks in the system.

Disk Shelves

A list of disk shelves, if supported, is displayed at the bottom of the view. The thumbnail to the left represents the front of the currently selected disk shelf. Clicking on the right pointing arrow or double-clicking on a row within the list will provide complete details about the disk shelf. The state indicator will be orange if the chassis contains any faulted components. The following fields are displayed in the list:

Property	Description
Name	Name of the disk shelf, used in faults and alerts. This is initially set to the serial number of the disk shelf, but can be changed by clicking on the name within the list.
Manufacturer	Disk Shelf Manufacturer
Model	Disk Shelf Model
Data	Total size of all data disks within the disk shelf.
Cache	Total size of all read-optimized cache devices ("Readzillas") within the drive shelf. There are currently no supported disk shelves with read cache devices, but this may not always be the case. If there are no cache devices within the shelf, then "-" is displayed.
Log	Total size of all write-optimized cache devices ("Logzillas") within the drive shelf. If there are no log devices within the shelf, then "-" is displayed.
Paths	Total number of I/O paths to the disk shelf. The only supported configurations are those with multiple paths to all disks, so this should read "2" under normal operating circumstances. Clicking the icon will bring up a dialog with information about each path. This includes which HBAs are connected to the disk shelf, and the state of any paths. 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 it displays two paths to the chassis.
Locate	Toggle the locate LED for this disk shelf. If the LED is currently on, then this indicator will be flashing. Note that individual disk shelves in the 7700 cabinet do not have Locate LEDs.

Chassis Detail

To view the chassis details, click on the icon (or one of the alternative forms described above). This view includes some of the same controls in the upper left (state, name, locate, reset, poweroff), as well as listings of all the components in the chassis.

At the left is a set of images describing the chassis. If there are multiple views, then you can switch between them by clicking on the name of the view above the image.

For each view, faulted components will be highlighted in red. In addition, the currently selected component will be highlighted in the image. Clicking on a component within the image will select the corresponding component in the list to the right.

A tab is present for each component type in the following list. Each component type has a state icon which will be orange if there is a faulted component of the given type.

Disk
Slot
CPU (controller only)
Memory (controller only)
Fan
Power supply (PSU)
Service processor (SP) (controller only)

Clicking on a component type will display a list of all physical locations within the chassis where components may be present. Clicking on a component within the list will highlight it within the appropriate chassis image. Clicking on the icon while over a row or double-clicking a row will bring up a dialog with detailed information about the component. The information displayed in the list depends on the component type, but is a subset of the information available in the component detail. Disks and service processors support additional operations described below. Each component can report any or all of the following properties:

Property	Description
Label	Human-readable identifier for this component within the chassis. This is typically, but not necessarily, equivalent to the label printed on the physical chassis.
FMRI	Fault managed resource identifier (FMRI) for the component. This is an internal identifier used to identify the component within faults and is intended for service personnel.
Active Problems	For a faulted component, links to active problems affecting the component.
Manufacturer	Component manufacturer.
Model	Component model.
Build	Manufacturing build identifier. This is used to identify a particular location or batch where the component was manufactured.
Part	Component part number, or core factory part number. The orderable part number may differ, depending on whether a component is for replacement or expansion, and whether it's part of a larger assembly. Your service provider should be able to refer you to the appropriate orderable part. For components without part numbers, the model number should be used instead.
Serial	Component serial number.
Revision	Firmware or hardware revision of the component.
Size	Total memory or storage, in bytes.
Type	Disk type. Can be one of 'system', 'data', 'log', 'cache', or 'spare'. When a spare is active, it will be displayed as 'spare '.
Speed	Processor speed, in gigahertz.
Cores	Number of CPU cores.
GUID	Hardware global unique identifier.

Disks

Disks support the additional options:

Action	Description
Locate	Toggle the locate indicator for the disk. If the LED is currently turned on, this icon will be blinking.
Offline	Offline the disk. This option is only available for disks that are part of a configured storage pool (including the system pool). Offlining a disk prevents the system from reading or writing to it. Faulted devices are already avoided, so this option should only be required if a disk is exhibiting performance problems that do not result in pathological failure. It is not possible to offline a disk that would prevent access to data (i.e. offlining both halves of a mirror). If the device is an active hot spare, this will also give the option of detaching the hot spare completely. Once a hot spare is detached, it cannot be activated except through another fault or hotplug event.
Online	Online the disk. Reverses the above operation.

Infiniband Host Controller Adapters

Infiniband Host Controller Adapters (HCA) report additional properties for the list of available ports:

Action	Description
State	When "active", the active port icon is displayed. Other valid port states ("down", "init", and "arm") are denoted by the inactive port icon . Mousing over the port icon will display the current port state in the tip pop-up.
GUID	The hardware assigned port GUID.
Speed	The current port speed enabled: Single Data Rate (SDR), Dual Data Rate (DDR) or Quad Data Rate (QDR)

Service Processor

The service processor behaves differently from other component nodes. Instead of providing a list of components, it presents a set of network properties that can be configured from the storage appliance. The following properties control the behavior of the service processor network management port.

Property	Description
MAC Address	Hardware MAC address. This is read-only
IP Address Source	Either 'DHCP' or 'Static'. Controls whether DHCP should be used on the interface.
IP Address	IPv4 Address, when using static IP configuration. IPv6 is not supported.
Subnet	Dotted decimal subnet, when using static IP configuration.
Default Gateway	IPv4 default gateway address.

Changing multiple values in conflicting ways (such as changing static IP assignments while in DHCP mode) has undefined behavior.

CLI

Hardware status details are available in the CLI under the maintenance hardware section. Use the show command to list the status of all components. The list command will list available chassis, which can be selected and then viewed using show.

tarpon:> maintenance hardware show
