This chapter explains how to use FAST to operate an enclosure¹. This chapter also provides instructions for working with enclosure properties.

Since enclosures vary widely, not all the features and functions described in this chapter may be present in your enclosure system. See the enclosure system documentation for details.

Note: This version of FAST supports only SAF-TE 1.0-compliant enclosures.

Understanding Enclosures

Figure shows how enclosures are represented in the Controller view window.

The Enclosure ID consists of the following:

Bus to which the enclosure is attached
SCSI ID of the enclosure attached to the bus (channel)
LUN number of the enclosure attached to the bus

Figure 1. Enclosures represented in Controller view

Working with Enclosure Properties

The Enclosure Properties dialog box contains information about the selected enclosure or active backplane.

To access the Enclosure Properties dialog box:

Select Controller View from the View menu.

Select an enclosure.

Select Properties from the Edit menu.The Enclosure Properties dialog box appears (Figure ).

OK button	Accepts changes, closes the dialog box, and sets the controller polling interval.

Set the controller's polling interval by selecting a setting from the Poll the controller's enclosures every list.

Note: Shorter polling intervals provide more up-to-date information; however, more time is needed for polling and less time is available for data I/O. (A shorter polling interval requires more frequent polling, resulting in a higher ratio of polling traffic to file- related data-transfer traffic on the SCSI bus.) Conversely, longer polling intervals provide less current information, but do allocate more time to data I/O.

See the following table if an exclamation point icon appears to the right of a subsystem icon:

If... Then...

An exclamation point appears to the right of the temperature sensor, fan or power supply icon Click Details next to the power supply icon. Look for problem information in the Enclosure Fans, Temperature Sensors and Power Supplies dialog box that appears (see Figure ).

If an exclamation point appears to the right of the slot icon Click Details next to the slot icon. Look for problem information in the Enclosure Slots dialog box that appears (see Figure ).

Click OK.

Managing Temperature Sensors

The elements in the Enclosure Fans, Temperature Sensors and Power Supplies dialog box enable you to view the status of temperature sensors and to set the warning threshold temperature (the user-specified temperature limit above which FAST displays a warning).

Displaying the Temperature Sensor Status

This section explains the two types of temperature sensors displayed in the Temperature Sensors list of the Enclosure Fans, Temperature Sensors and Power Supplies dialog box.

The status of the temperature sensors in the enclosure is indicated as follows:

Type 1 temperature sensors

Type 1 temperature sensors report enclosure temperatures as a number. If the enclosure reports one or more type 1 temperature sensors, as indicated in the Enclosure Properties dialog box, the status of these sensors is displayed as in the following table.

Status Explanation

Fahrenheit

Temperature at x ° F The current temperature is as indicated.

Over warning: x ° F The temperature has exceeded the limit displayed in the Warn above list.

Over limit: x ° F The temperature has exceeded the limit set by the manufacturer.

Celsius

Temperature at x.x ° C The current temperature is as indicated.

Over warning: x.x ° C The temperature has exceeded the limit displayed in the Warn above list.

Over limit: x.x ° C The temperature has exceeded the limit set by the manufacturer.
The Display in list and the Warn above list, along with their adjacent icons, are displayed only if one or more type 1 sensors are reported by the enclosure.
Note: The Enclosure Properties dialog box displays only the number of type 1 temperature sensors (see Figure , ).

Type 2 temperature sensors

Type 2 temperature sensors report a binary value, which indicates that a temperature is either over or under a preset value. If the enclosure does not report any type 1 temperature sensors, the status of up to 15 type 2 sensors is displayed in the Temperature Sensors list as follows:

OK (or no sensor present)

Over limit

Note: The SAF-TE 1.0 specification does not provide a means for FAST to determine the number, or the existence, of type 2 temperature sensors. Therefore, when FAST does not report any type 1 temperature sensors, it displays the status of 15 potential type 2 sensors. If a type 2 temperature sensor is not indicating an over- temperature condition, or does not exist, the status of the sensor is displayed as OK (or no sensor present).

Setting the Warning Threshold Temperature

To set the warning threshold temperature, select a number from the Warn above list.

Setting a Temperature Unit

To set a temperature unit, select Fahrenheit or Celsius from the Display in list.

The following dialog box elements display the selected temperature unit:

All type 1 temperature sensors displayed in the Temperature Sensors list (° F or ° C)
The Display in list (Fahrenheit or Celsius)

Displaying Fan Status

The elements in the Enclosure Fans, Temperature Sensors and Power Supplies dialog box enable you to view the status of the fans reported by the enclosure and to set the speed of the fans.

The status of the fans in the enclosure is displayed in the Fans list as follows:

Setting Fan Speed

To set the speed of all fans at once, click Set all and select a speed (or Off) from the Set all list.

To set the speed of a single fan, select a fan from the Fans list, click Set, and select a speed (or Off).

Note: Some enclosures report fan status but do not allow speed control. See your enclosure documentation for details.

Displaying Power Supply Status

The elements in the Enclosure Fans, Temperature Sensors and Power Supplies dialog box enable you to view the status of the power supplies reported by the enclosure and to turn the power supplies on and off.

The status of the power supplies in the enclosure is displayed in the Power Supplies list as follows:

(black icon)

(black icon)

(red icon)

(red icon)

Turning Power Supplies On and Off

To turn a power supply on or off:

Select a power supply from the Power Supplies list.
Click Set.
Select On or Off from the list that appears.
Note: Some enclosures report power supply status, but do not allow on/off control. For more information, see your enclosure documentation.

Managing Enclosure Slots

The elements in the Enclosure Slots dialog box (Figure ) enable you to view the status of and manage enclosure slots.

To view and configure enclosure slots:

Select Controller view from the View menu.
Select an enclosure.
Select Slots from the Enclosure menu.

The Enclosure Slots dialog box appears (Figure ).

Click Close.

Displaying Slot Status

The Enclosure Slots dialog box displays the identifiers shown in the following table for each slot reported by the enclosure:

Identifier Function Valid Value

Slot # Displays the number assigned to the slot by the enclosure 00 through nn (where nn equals the number of slots reported by the enclosure minus 1; single digits are preceded by a 0)

Current SCSI ID Displays the SCSI ID currently assigned to the slot 00 through 15; --- for none

New SCSI ID Displays the new SCSI ID before it is assigned to the slot 00 through 15; --- for none

Activate a slot for use on the SCSI bus
Identify a slot
Prepare a slot for insertion and/or removal of a device
Change a slot's SCSI ID
Show SCSI ID conflicts

Activating a Slot for SCSI

The controller automatically activates a slot when it detects that a new device has been inserted.

To activate a slot for use on the SCSI bus:

Click a slot in the Slots list where the entry in the SCSI Activated column is "---".
Click Activate SCSI.

The SCSI Activated status changes from "---" to Act.

Identifying a Slot

To identify a slot:

Click a slot in the Slots list.
Click Identify On.

How the device is identified depends on the enclosure manufacturer. For example, the enclosure may flash a series of lights on its associated slot door.

To turn off slot identification:

Click a slot in the Slots list.
Click Identify Off.

Preparing One or More Slots for Insertion/Removal

To prepare one or more slots for insertion or removal of a device:

Select a slot from the Slots list.
Click Prepare for Insert/Remove.

¹ Some servers offer SCSI backplanes that respond to SAF-TE commands. In this user's guide, the word enclosure means an independent SAF-TE enclosure or a SAF-TE-compliant backplane.
