This chapter describes how to configure and manage arrays attached to non-RAID SCSI subsystem controllers. You can display your system's non-RAID SCSI subsystem controllers in the Array Manager tree view by doing the following:
- Expand the Arrays object in the Array Manager tree view hierarchy.
- Expand the SCSI Subsystem object. This action displays the non-RAID SCSI controllers included in your system.
The following controllers are supported by the SCSI subsystem:
- Adaptec Ultra SCSI Controllers (40 MB device speed). These controllers include the 3944UW, 2944UW, AIC-7860, and AIC-7880 controllers. The AIC-7860 and AIC-7880 controllers are an ASIC embedded on the motherboard.
- Adaptec Ultra2 SCSI Controllers (80 MB device speed). These controllers include the 2940U2W and AIC-7890 controllers. The AIC-7890 controllers are an ASIC embedded on the motherboard.
- Adaptec Ultra160 SCSI Controllers (160 MB device speed). These controllers include the 39160, 29160LP, AIC-7899, and AIC-7892 controllers. The AIC-7892 and AIC-7899 controllers are an ASIC embedded on the motherboard.
The SCSI subsystem controllers are non-RAID controllers that support SCSI devices. Because these controllers are non-RAID, they do not support virtual disks. You can manage these non-RAID controllers and their attached SCSI devices with Array Manager.
The Ultra SCSI controllers supported by Array Manager are a high voltage differential (HVD) SCSI drop-in controller that fits in a PCI slot on the server or is embedded in the server. This controller can be used to attach HVD devices such as an HVD tape drive.
The Ultra2 SCSI and Ultra160 SCSI controllers are low voltage differential (LVD) drop-in controllers that fit in a PCI slot on the server or are embedded in the controller. These controllers can be used to attach external enclosures and other LVD SCSI devices.
Array Manager also supports RAID controllers on which you can create virtual disks. For information on these controllers, see the following:
- PERC Subsystem 1 Controllers: PERC 2/SC, 2/DC, 3/SC, 3/DCL, 3/DC, 3/QC, 4/SC, 4/DC, 4/Di, 4/IM, and CERC ATA100/4ch (SCSI controllers)
- PERC Subsystem 2 Controllers: PERC 2, 2/Si, 3/Si, and 3/Di (SCSI controllers)
- The Dell PowerVault 660F Storage System (fiber channel controller)
Working with these controllers requires an understanding of the Array Manager storage model, which represents the Array Manager storage objects in an object hierarchy. Each object has a set of attributes and operations associated with it. Attributes describe the properties of the object, and operations allow you to create new objects and modify existing object attributes. See "The Array Manager Storage Model" section in the "Storage Management Concepts" chapter for more information about the Array Manager storage model.
Unless otherwise stated, each operation described in this chapter is available on each controller type listed above. Operations that are inactive (dimmed) in the console are not supported or not available at that time. To view attributes or to perform operations, right-click a given storage object. A context menu will appear with a list of commands available, including a Properties command.
Because the controllers in each subsystem support different features, the objects in the expanded tree view may vary for each subsystem. For example, the SCSI subsystem does not support virtual disks. Therefore, the SCSI subsystem does not have an Array Group or Virtual Disk object in the tree view.
The SCSI subsystem has the following commands on its pop-up menu:
This command enables you to view a report on the SCSI subsystem. The report indicates the current status of the SCSI controller.
To view a report on the SCSI subsystem:

- Dell PowerVault 201S (PV201S)
- Dell PowerVault 210S (PV210S)
- Dell PowerVault 211S (PV211S)
- Dell PowerVault 220S (PV220S)
- Dell PowerVault 221S (PV221S)
In addition to managing the hard disks contained in the enclosure, you can monitor the status of the enclosure's EMMs, fans, power supply, and temperature probes. You can view these components in the Array Manager tree view.
Array Manager displays the properties of the enclosure's EMMs, fans, power supply, and temperature probes. Array Manager also notifies you of enclosure status changes through events that are displayed on the Events tab and logged in the Windows event log.
The following sections provide more information on the enclosure components managed by Array Manager:
When you expand the storage subsystem object in the Array Manager tree view, you see the controllers attached to the storage subsystem. The controller object expands to display the controller's channels. These channel objects are numbered in the Array Manager tree view to match the channel number that appears on the controller hardware. (See the controller's documentation for information on identifying the channels on the controller hardware.) For example, if the controller has two channels numbered 0 and 1, then the channel objects in the Array Manager tree view are named Channel 0 and Channel 1.
Expanding the enclosure channel object displays the enclosure's fans, power supply, and temperature probes. Each of these objects expands to display the individual fans and so forth provided by the enclosure.
For more information on the enclosure's components, commands, and the hard disks included in the enclosure, see the following sections:
The fans that are installed in the enclosure are displayed under the Fans object in the tree view. You can select the Fans object to display the individual fans and their status information in the right pane. You can also expand the Fans object to display the individual fans in the left pane.
If you right-click the Fans object or an individual fan, a context menu is displayed with a Properties option. For more information on fan properties, see "Fan Properties."
The power supplies that are installed in the enclosure are displayed under the Power Supplies object in the tree view. You can select the Power Supplies object to display the individual power supplies and their status information in the right pane. You can also expand the Power Supplies object to display the individual power supplies in the left pane.
If you right-click the Power Supplies object or an individual power supply, a context menu is displayed with a Properties option. For more information on power supply properties, see "Power Supply Properties."
The temperature probes that are installed in the enclosure are displayed under the Temperature Probes object in the tree view. You can select the Temperature Probes object to display the individual temperature probes and their status information in the right pane. The status information in the includes the current temperature in celsius and the warning and error thresholds for the temperature probe. The error threshold has a default value that cannot be changed. You can set the warning threshold, however. See "Set Thresholds for Temperature" for information on setting the warning threshold.
Right-clicking the temperature probes object in the left pane displays a context menu with a Properties option. You can also expand the temperature probe object to display the individual temperature probes in the tree view. Right-clicking an individual temperature probe also displays a context menu with a Properties option. This option enables you to set the minimum and maximum warning threshold for the temperature probe.
For information related to the enclosure's temperature, see the following:
The Enclosure Management Modules (EMMs) that are installed in the enclosure are displayed under the EMMs object in the tree view. You can select the EMMs object to display the individual EMM modules and their status information in the right pane. You can also expand the EMMs object to display the individual EMM modules in the left pane.
The enclosure may contain one or more EMMs. The EMM modules monitor components of the enclosure. These components include:
- Fans
- Power supplies
- Temperature probes
- The insertion or removal of a drive
- The LEDs on the enclosure
When the enclosure's alarm is enabled, the EMM activates the alarm when certain conditions occur. For more information on enabling the alarm and the conditions that activate the alarm, see "Enable Alarm." For more information on EMMs, see the enclosure hardware documentation.
If you right-click the EMMs object or an individual enclosure management module, a context menu is displayed with a Properties option. You can view the properties of each individual EMM module to verify that all EMM modules are at the same firmware level. (All EMM modules in the enclosure should have the same version of firmware.) For more information on enclosure management module properties, see "EMM Properties."
For information on downloading firmware for an EMM module, see "Download Firmware."
This section describes the commands associated with the enclosure and its fans, power supplies, and temperature probes. For the commands associated with an enclosure's hard disks, see "SCSI Subsystem Hard Disk Commands."
Right-clicking an enclosure object in the tree view displays a context menu with the enclosure commands. Right-clicking the enclosure's fans, power supplies, and temperature probes also displays context menu for these components.
The commands on the enclosure's context menu can vary depending on the model of the enclosure. Enclosure context menu commands may include:
- Rescan — Checks whether any new hard disks and other components such as fans or temperature probes have been added to the enclosure.
- Enable Alarm — Enables an audible alarm that sounds whenever the fault LED lights.
- Disable Alarm — Turns off the audible alarm settings. If the alarm is already sounding, you can turn it off with this command.
- Set Tag Data — Allows you to enter or change asset information for the enclosure.
- Download Firmware — Allows you to download firmware to the enclosure.
- Enclosure Properties — Displays enclosure properties.
- Set Thresholds for Temperature — Sets the minimum and maximum values for the temperature warning threshold. This command is not located on the enclosure's context menu. It is located on the context menu for the individual temperature probes.
The context menu commands for EMMs, fans, power supplies, and temperature are:
- EMM Properties — Displays enclosure management module (EMM) properties.
- Fan Properties — Displays fan properties.
- Power Supply Properties — Displays power supply properties.
- Temperature Properties — Displays temperature properties. To set the temperature threshold, expand the temperature probes object to display the individual temperature probes in the tree view. The properties for an individual temperature probe enable you to set the warning thresholds.

- Right-click the temperature probe for which you are setting the warning threshold and select Properties from the context menu. This action displays the Temperature Probe Properties dialog.
The Temperature Probe Properties dialog displays the current status of the
temperature probe as well as the default values in celsius for the minimum and
maximum error thresholds. The default values for the error thresholds indicate that
the enclosure has reached a dangerous temperature that may cause damage. These
default values cannot be changed.
- Enter the desired value in celsius for the minimum and maximum warning thresholds in the Minimum Warning Threshold and the Maximum Warning Threshold fields. The warning thresholds indicate that the enclosure is approaching an unacceptably warm or cool temperature.
If you wish to apply your changes to all temperature probes in the enclosure, then
select the Apply these values to all temperature probes in the enclosure check box.
- Click Apply and then Ok to make the changes. Click Cancel to exit the function without accepting the changes.
For information related to the enclosure's temperature, see the following:
This section describes procedures commonly used in association with enclosures. For additional information on enclosure commands and properties, see "Enclosure Commands" and "Enclosure Properties."
The enclosure procedures are as follows:
If you have not yet attached the enclosure to an open channel, you may need to identify a channel on the controller that can be used for this purpose. To identify an open channel:
- Expand the Array Manager tree view until the controller object is expanded. When the controller object is expanded, the tree view displays the controller's channels. These channels are numbered starting from zero.
- Identify a channel that is not attached to storage. When a controller's channel is attached to an enclosure or an array, the channel object can be expanded to display the disks included in the array or the enclosure. A channel object that cannot be expanded in the Array Manager tree view is an open channel not currently attached to storage. Array Manager displays a number for each channel. These numbers correspond to the channel numbers on the controller hardware. You can use these numbers to identify which open channel displayed in the tree view is the open channel on the controller hardware.
You can view the current status of an enclosure and its components. To view status information, select the object for which you wish to see the status in the tree view. In the right pane, the Status field indicates the current status. The possible values are:
- Ready — Indicates that the enclosure or its component is functioning normally.
- Offline — Indicates that the enclosure or its component is not accessible. The enclosure or its component may be removed.
- Failed — Indicates that the enclosure or its component has experienced a failure and is no longer functioning.
For information on enclosure events displayed in the Array Manager event log, see "Events Generated by the PERC 2/SC, 3/SC, 2/DC, 3/DCL, 3/DC, 3/QC, 4/SC, 4/DC, 4/Di, CERC ATA100/4ch and the PERC 2, 2/Si, 3/Si, and 3/Di Controllers."
To check the enclosure's temperature, select a temperature probe object in the tree view. The temperature reported by the temperature probe is displayed in celsius in the Current Value field in the right pane.
For information related to the enclosure's temperature, see the following:
