Hardware Installation and Removal
This chapter describes the tasks required to install and remove the HBA. Refer to your system installation or service manual for detailed instructions.
This chapter contains the following topics:
To minimize the possibility of ESD-related damage, Sun strongly recommends using both a workstation antistatic mat and an ESD wrist strap. You can get an ESD wrist strap from any reputable electronics store or from Sun as part number #250-1007. Observe the following precautions to avoid ESD-related problems:
The hardware installation process involves the following general steps:
The following sections describe these steps in more detail.
1. Attach an antistatic strap (refer to Observing ESD and Handling Precautions).
2. Refer to your system installation or service manual to determine an appropriate ExpressModule slot in which to install the HBA.
3. Press down the plastic tab to release the ExpressModule latch and pull the lever out until it is nearly perpendicular with the ExpressModule front panel.
4. Insert the HBA into its slot, being careful that the tooth on the bottom of the lever does not come in contact with the chassis sheet metal during insertion.
5. When the HBA is inserted nearly all the way into its slot, push the lever back into its fully closed position, allowing the lever tooth to insert the HBA fully into place.
Use multimode fiber-optic cable, intended for short-wave lasers, that adheres to the specifications in TABLE 2-1.
Follow these steps when connecting the optical cable:
1. Connect the fiber-optic cable to an LC connector on the HBA (see FIGURE 2-2).
2. Connect the other end of the cable to the FC device.
After the optical cable is connected to the HBA, you are ready to apply power to the system. If power is already applied to the system, proceed to Configuring the HBA for Hot-Plug Operation.
1. Verify that the HBA is securely installed in the system.
2. Verify that the correct optical cable is attached.
3. Refer to your system installation or service manual to determine how to power up the system blade.
4. Observe the light-emitting diodes (LEDs) status for the power-on self test (POST) results as shown in TABLE 2-2.
TABLE 2-2 summarizes LED indicator combinations. Refer to FIGURE 2-3 to determine the location of the LEDs. Each port has a corresponding set of LEDs that provide a visual indication of the operating state.
1. Use the cfgadm command to verify proper HBA installation:
If the HBA is properly installed and connected, you should see output similar to the following:
2. If an HBA adapter is shown as unconfigured or disconnected, use the cfgadm -c configure command to configure the adapter.
1. Use the cfgadm command to verify attached storage:
If the HBA is properly installed and storage is connected properly, you should see output similar to that shown below. In this example, one port of an HBA adapter is connected through a fabric switch to two ports of a disk array.
2. If an adapter is shown as unconfigured, use the cfgadm -c configure command to configure it.
1. Locate the green Power LED indicator near the bottom of the HBA front panel.
Power LED indicator status is as follows:
2. If the green Power indicator is not illuminated, briefly press the Attention button near the bottom of the HBA front panel.
The green power LED should blink for approximately five seconds and then remain on, indicating that the HBA has been properly configured.
To cancel the operation, press the button again before it stops blinking.
The following instructions describe the tasks required to remove the HBA. Refer to your system installation or service manual for detailed HBA adapter removal instructions.
The hardware removal process involves the following general steps:
1. Either halting the operating system and removing power from the server blade, or preparing the HBA for hot-plug removal with one of the following:
2. Removing the HBA hardware
1. Press and release the Attention button near the bottom of the HBA front panel.
The green Attention LED near the button should blink for approximately five seconds, indicating that the HBA is being prepared for removal.
If you want to abort the operation, press the button again before the LED stops blinking.
2. After the Attention LED goes dark, remove the HBA.
If you want to remove the HBA without first halting the operating system and removing power from the associated server blade, you may first prepare it for removal as follows:
1. Use the cfgadm command to identify the HBA to be removed.
2. Use the cfgadm -c unconfigure command to unconfigure the attachment point ID (Ap_Id) for the HBA.
3. Use the cfgadm -c disconnect command to prepare the HBA for removal.
A flashing Power indicator LED indicates that the HBA is being prepared for removal. A dark Power indicator LED indicates that the HBA is ready to be removed.
Press the HBA latch to disengage the HBA, and then pull forward and down to eject it.
You should then be able to easily remove the HBA.
