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).

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.
|

|
|
- Maximum RAIDs (allowed logical volumes for controller)
|
|
|
- Maximum hot spares (allowed dedicated hot spares for single RAID)
|
|
RAID Controller Disk Properties (shown in ILOM CLI under /STORAGE/raid)
|
|
|

|
- Dedicated hot spare (for disk)
|
|
- Disk capacity (supported size in byte)
|
- Global hot spare (for disk group)
|
|
|
- RAID IDs (list for this device)
|
|
- 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 volume status (OK, degraded, failed, missing)
|
- Device name, known by host operating system
|
- Targets for child member of RAID ID
|
|
|
|
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 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
For web 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 Web Interface Procedures Guide
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).
