Storage Monitoring for HDDs and RAID Controllers

As of ILOM 3.0.6, ILOM supports additional storage monitoring functions for viewing and monitoring storage details that are associated with system hard disk drives (HDDs) and RAID controllers. These enhanced storage property details are available in ILOM from the CLI (as of ILOM 3.0.6) and the web interface (as of ILOM 3.0.8).

Note - Some Oracle Sun servers might not enable support for the storage monitoring functions that are described in this chapter. To determine whether storage monitoring support on your server has been enabled, see the ILOM Supplement guide for your server. For Oracle Sun servers supporting the Storage Monitoring feature in ILOM, a system management pack must be installed to use the Storage Monitoring features. For information about how to download this management pack, see Oracle Server Hardware Management Pack User’s Guide (821-1609).

- Monitoring Storage Components Using the Web Interface

### CLI Storage Properties Shown for HDDs and RAID Controllers

Using the ILOM CLI, you can view the following properties (TABLE 5-1) that are associated with your system server HDDs and RAID controller options.

Note - The storage properties appearing in TABLE 5-1 might not be available for all storage configurations.

TABLE 5-1 Storage Properties Shown for HDDs and RAID Controllers
HDD Storage Properties (shown in ILOM CLI under /SYS)
Disk type (SATA or SAS) | OK to remove status | HBA ID for controller
FRU type (hard disk) | Service fault state | HBA ID for disk
FRU name | Present device state | RAID status (online, offline, failed, missing, and so on)
FRU part number | Disk capacity | RAID dedicated hot-spare (for disk)
FRU serial number | Device name | RAID global hot-spare (disk group)
FRU manufacturer | World Wide Name (WWN) | RAID ID list that is applicable to the HDD
FRU version | FRU description |
RAID Controller Properties (shown in ILOM CLI under /STORAGE/raid)
FRU manufacturer | PCI subdevice | Maximum global hot spares (allowed number of global hot spares for controller)
FRU model | RAID levels supported | Minimum stripe size (supported size in kilobytes)
PCI vendor ID | Maximum disks (allowed disks for controller) | Maximum stripe size (supported size in kilobytes)
PCI device ID | Maximum RAIDs (allowed logical volumes for controller) |
PCI subvendor ID | Maximum hot spares (allowed dedicated hot spares for single RAID) |
RAID Controller Disk Properties (shown in ILOM CLI under /STORAGE/raid)
FRU name | FRU version | World Wide Name (WWN)
FRU part number | RAID status (offline, online, failed, missing, initializing) | Dedicated hot spare (for disk)
FRU serial number | Disk capacity (supported size in byte) | Global hot spare (for disk group)
FRU manufacturer | Device name | RAID IDs (list for this device)
FRU description | Disk type (SAS or SATA known by host operating system) | System drive slot (corresponding internal hard drive NAC name for RAID)
RAID Controller Volume Properties (shown in ILOM CLI under /STORAGE/raid)
RAID level | Mounted status | Stripe size
RAID volume status (OK, degraded, failed, missing) | Device name, known by host operating system | Targets for child member of RAID ID
Disk capacity | Resync status |

#### RAID Status Definitions for Physical and Logical Drives

When a physical disk is configured as part of a volume and is attached to a powered-on controller, ILOM reports one of the following status values for configured physical (TABLE 5-2) and logical (TABLE 5-3) drives.

TABLE 5-2 RAID Status Definitions for Physical RAID Disks
Physical RAID Disk ID Status
OK | The disk is online.
Offline | The disk is offline per host request or for another reason such as disk is not compatible for use in volume.
Failed | The disk has failed.
Initializing | The disk is being initialized or rebuilt.
Missing | The disk is missing or not responding.
Unknown | The disk is not recognized.

TABLE 5-3 Status Definitions for Logical RAID Volumes
Logical RAID Volume Status
OK | The volume is running at optimal level.
Degraded | The volume is running in degraded mode. An additional disk loss could result in permanent data loss.
Failed | The volume has too many failed disks and is not running.
Missing | The volume is not found or not available.
Unknown | The volume is not recognized or is not defined.

### Monitoring Storage Components Using the CLI

To view and monitor storage details related to the HDDs and RAID controllers that are configured on your system, log in to the ILOM CLI and drill down the following target properties under:

- `/SYS/` to show details for HDDs

or

- `/STORAGE/raid` to show details for a RAID disk controller

For CLI procedures about how to view and monitor storage properties in ILOM, see the section about Viewing and Monitoring Storage Components in the Oracle Integrated Lights Out Manager (ILOM) 3.0 CLI Procedures Guide

### Monitoring Storage Components Using the Web Interface

To view and monitor storage details related to the HDDs and RAID controllers that are configured on your system, log in to the ILOM web interface and drill-down to the web interface Storage --> RAID tabs. From the RAID tab, you can view and monitor details about:

- Raid controllers (Controller tab) - see RAID Controllers Tab Details.

- Disks attached to RAID controllers (Disk tab) - see Disks Attached to RAID Controllers Details.

- RAID controller volume details (Volumes tab) - see RAID Controller Volume Details.

#### RAID Controllers Tab Details

From the Storage --> RAID --> Controller tab in ILOM, you can access configuration information about each RAID controller installed on your system. This information includes:

- RAID controller configuration details that describe the RAID levels, maximum number of disks, and the maximum number of RAIDs that can be configured on each installed RAID controller. For example, see FIGURE 5-1.

- RAID controller FRU properties and values for each installed RAID controller. For example, see FIGURE 5-2.

- RAID controller topology details that display information about attached disks, configured RAID volumes, and disks that are part of a RAID. For example, see FIGURE 5-3.

FIGURE 5-1 RAID Controller Configuration Details

FIGURE 5-2 RAID Controller FRU Properties and Values

FIGURE 5-3 RAID Controller Topology Details

#### Disks Attached to RAID Controllers Details

From the Storage --> RAID --> Disks tab in ILOM, you can access configuration information about the disks that are attached to your RAID controllers. This information includes:

- Disk configuration details for each disk attached to a RAID controller. These details include the disk name, status, serial number, capacity, and device name. For example, see FIGURE 5-4.

- Disk FRU properties and values for each disk attached to a RAID controller. For example, see FIGURE 5-5.

FIGURE 5-4 Disk Details - Attached to RAID Controller

FIGURE 5-5 Disk FRU Properties and Values

#### RAID Controller Volume Details

From the Storage --> RAID --> Volume tab in ILOM, you can access configuration information about the RAID volumes that are configured on RAID controllers. This information includes:

- Volume configuration details for each volume configured on a RAID controller. These details include the volume name, status, RAID level, capacity, and device name. For example, see FIGURE 5-6.

- Volume properties and values for each volume configured on a RAID controller. For example, see FIGURE 5-7.

FIGURE 5-6 RAID Volume Configuration Details

FIGURE 5-7 RAID Volume Properties and Values

CMM Zone Management Feature

As of ILOM 3.0.10, a new zoning management feature is available on the CMM for SAS-2 storage devices that are installed in Oracle Sun Blade 6000 or Sun Blade 6048 Modular Systems.

For more information about how to manage SAS-2 chassis storage devices from ILOM, see the section about Zone management in the Oracle Integrated Lights Out Manager (ILOM) CMM Administration Guide for Sun Blade 6000 and Sun Blade 6048 Modular Systems (820-0052).
