Properties — Status (real-time only)

Use this page to quiesce and to resume hardware resources and to view the status of hardware resources that you have selected in the main Properties page.

Introduction

This page allows you to view and modify the status and state of the selected hardware resource. You must select a hardware resource before you can select an action to perform on the resource. The Service effect action opens the service effect for the selected hardware resource. The Take offline action quiesces a hardware resource in preparation for a repair or replace procedure. The Bring online action resumes a hardware resource after you complete a repair or replace procedure.

This page is only available when you are operating in real-time mode. It is not available in simulated mode.

Fields

Storage complex

The user-assigned name of the storage complex that contains the resources that are summarized.

Storage unit

The user-assigned name of the storage unit that contains the resources that are summarized.

Enclosure

The number of the enclosure that contains the resources that are summarized. Values can be 00 through 06 and 10 through 16, depending on the number of enclosures that are available on the selected storage unit.

Resource

The name of the resource that is summarized in the work area. Click the link to view detailed properties for the resource. Values are Storage Unit, Array, Rank, Volume (FB), Volume (CKD), Battery Backup Unit, Disk Drive Module, Front Display Panel, Enclosure, Power Supply/Fan, Processor Controller Card, or Rear Display Panel.

Set auto refresh rate (storage unit status only)

Determines how frequently the page automatically refreshes.

Refresh button

Refreshes the information in the summary table. The last refresh date and time are also updated.

Last refresh

The most recent date and time of the information that is displayed in the summary table.

Select

Select a hardware resource from one of the enclosure images.

Class (DDM only): The disk class, either enterprise or near-line. Enterprise is a high end disk drive and has the highest reliability. Near-line is a lower end disk drive, and has lower reliability than enterprise disk drives. Near-line storage is a compromise between online storage (constant, very rapid access to data) and offline storage (infrequent access for backup purposes or long-term storage). Near-line storage is for applications that require quicker random access compared to offline storage, but do not require the continuous, instantaneous access provided by online storage.

Status and States

Status is the current condition of the resource. The values are Normal, Attention, Alert, or Discovery. Click on the link to view a detailed status of a physical resource or the detailed properties of a logical resource.

Normal Status

A normal status indicates that the hardware resource is functioning properly. The following states indicate that the hardware resource has a normal status:

Normal: The resource is operational and functional.
Installing: A new resource has been recognized. It is either a replacement resource for a failed resource or it is additional capacity that you are adding.
Verifying: The resource is made accessible to the device adapter, its characteristics are determined, cabling is checked, and diagnostics are run.
Formatting: A verified resource requires low-level formatting and the formatting operation is in progress.
Initializing: The resource is being initialized with all zero sectors. This is required so that the resource can be added to an array without regenerating parity.
Certifying: The resource is being read accessed to determine that all sectors can be read. If a bad sector is detected, an alternate sector is used to replace the bad sector.
Rebuilding: Sparing has occurred and this formerly spare resource is being rebuilt with data from the other resources in the array to which it now belongs.
Migration target: DDM migration is migrating another array member resource to this spare resource.
Migration source: DDM migration is migrating this array member resource to another spare resource.
New: The resource is new. Integration of the resource into the system has not begun.

Attention Status

An Attention status indicates that the hardware resource may be missing from its slot, has been taken offline, or is faulty but still functioning. User intervention is required for this status. The following states indicate that the hardware resource has an Attention status:

Missing: The resource is missing. The resource has been pulled out of the system and removal has not been managed.
Missing, failed: The resource is missing and the previous state of the device was Failed before it was pulled from the enclosure.
Removed: The resource is removed. The resource is not in the system and its removal has been managed.
Removed, failed: The resource is removed from the system and removal has been managed. The previous state was Missing, failed.
Inappropriate: The resource is inappropriate for the system. For example, a DDM that is of the wrong capacity or rpm, or a hardware resource that cannot be integrated in that slot. However, the resource is not failed and might be valid for other systems and locations.
Interfailed: The resource is operational, but faulty. The resource will fail soon and should be replaced as soon as possible.

Alert Status

Alert status indicates that the hardware resource has failed and needs to be replaced, or that there is a problem that is associated with the hardware resource. The hardware resource returns to normal state when the problem is resolved. (For example, a power supply with a missing ac cable connection). The following states indicate that the hardware resource has an Alert status:

Failed: The resource has failed and an immediate repair action is required. If spares are available, sparing has been initiated if this resource is an array member.
Failed, deferred service: The resource has failed and a repair action is not immediately required. If this resource is an array member, sparing has been initiated, and there are sufficient spares at the time of this failure to allow the service action to be deferred.

Discovery Status (storage unit status only)

Discovery status indicates that the storage unit is in the progress of being identified. The percent complete is displayed, along with a short description of the discovery status.

0-4% - DA Logical Name Discovery: Discovery of the device adapter logical name.
5-14% - Upgrading firmware utilities: Upgrading firmware.
15-19% - Enclosures: Physical discovery of enclosures.
20-21% - Storage Unit: Discovery of the machine type, machine serial number and storage facility objects.
22-23% - Storage Complex: Discovery of storage complex attributes.
26-27% - Device and Host adapters: Discovery of device adapters and host adapters.
28-29% - Network Ports: Discovery of network adapters.
30-31% - Processor Controller Cards: Discovery of processor controller cards.
32-33% - Expansion Cards: Discovery of expansion cards.
34-35% - Power Supply and Fan units: Discovery of power supply and fan units.
36-39% - Battery Units: Discovery of battery units.
40-89% - DDM Integration: Discovering disk drive modules and integrating new ones.
90-99% - Finishing: Finishing storage unit discovery.
100% - Complete: Completed discovery.

Actions

Logs: Displays the log information for the selected resource.
Take offline: Opens a confirmation dialog that asks if you are sure that you want to take the selected resource offline. If you confirm, the selected resource is brought to a state in which its removal does not have adverse effects on the system. A progress indicator is displayed if this is a long-running task. If you cancel, the confirmation dialog closes and no action is performed.
Bring online: Opens a confirmation dialog asking if you are sure that you want to bring the selected resource online. If you cancel, the dialog closes and no action is performed. If you confirm, the selected resource is resumed. A progress indicator is displayed if this is a long-running task. If the resource resumes successfully, you receive a dialog that shows that the state of the resource has changed from offline to online. If the resource does not resume successfully, you receive a dialog that reflects the error and provides further instructions.
This option is not available for the battery backup unit, front display panel, or rear display panel. You cannot resume components that are in a quiescing, resuming, or online state.
