operations are possible while the background initialization is running. However, other processes such as

creating a virtual disk, cannot be run concurrently with background initialization. These processes cause

the background initialization to cancel.

Non-RAID Controller Description

The non-RAID SCSI and SAS controllers are non-RAID controllers that support SCSI and SAS devices.

Because these controllers are non-RAID, they do not support virtual disks. You can manage these non-

RAID controllers and their attached SCSI and SAS devices with Storage Management.

NOTE: Supported features may vary from controller to controller.

Non-RAID SCSI Controllers

The Broadcom PCIe U320 non-RAID controllers use Small Computer System Interface (SCSI) technology.

Non-RAID SAS Controllers

The following non-RAID controllers use Serial Attached SCSI (SAS) technology:

• SAS 6 Gbps Host Bus Adapter (HBA)

• Broadcom SAS 9207-8e

• Broadcom SAS 9300-8e

• Broadcom SAS 9206-16e

• SAS 12 Gbps HBA

• HBA 330

NOTE: Storage Management only enumerates and provides the PCI slot information for Broadcom

SAS 9207-8e and SAS 9300-8e controllers. As Storage Management does not monitor these non-

RAID controllers, devices connected to these controllers are not enumerated, alerts are not logged,

and SNMP traps are not sent for these controllers.

NOTE: In Storage Management, the Broadcom SAS HBA controller page display properties such as:

ID, Status, Name, Slot ID, State, Driver Version, Storport Driver Version, Number of Connectors,

and Controller Tasks.

NOTE: When a backplane without an expander (passive backplane) is connected to an HBA 330

controller, the enumeration of the physical disks is split between

Connector 0 and Connector 1. For

example, if the passive backplane is populated with a maximum of eight physical disks, the first four

physical disks are listed under Connector 0 and the remaining four physical disks are listed under

Connector 1. You will be able to view all the eight physical disks only if both bays are connected. If

one bay is connected, only the physical disks associated with that bay are displayed.

NOTE: For SAS 12 Gbps HBA and HBA 330 controller, the Available Reports that can be viewed are

View Slot Occupancy Report and View Physical Disk Firmware Version Report.

NOTE: At times, the connector ID for SAS 12 Gbps HBA may not be displayed correctly on Storage

Management. This occurs because of a firmware limitation in the SAS 12 Gbps HBA. However, this

connector ID discrepancy does not cause any functional limitation.
