Replacing Hot-Swappable and Hot-Pluggable Components

This chapter describes how to remove and replace the hot-swappable and hot-pluggable field-replaceable units (FRUs) in the Sun Blade T6300 server module.

The following topics are covered:

3.1 Hot-Pluggable Hard Drives

Hot-pluggable devices are those devices that can be removed and installed while the system is running, but you must perform administrative tasks first. The Sun Blade T6300 server module hard drives can be hot-swappable (depending on how they are configured).

For information about a hot-swappable or hot-pluggable PCI ExpressModule (PCI EM) or network express module (NEM), see the Sun Blade 6000 Modular System Service Manual, 820-0051.

3.2 Hot-Plugging a Hard Drive

The hard drives in the Sun Blade T6300 server module are hot-pluggable, but this capability depends on how the hard drives are configured.

3.2.1 Rules for Hot-Plugging

To safely remove a hard drive, you must:

Hard drives cannot be hot-plugged if:

If your drive falls into these conditions, you must shut the system down before you replace the hard drive. See Section 4.2.2, Shutting Down the System.

3.2.2 Removing a Hard Drive

For more information about the cfgadm and hard drive management commands see the Solaris man pages.

1. Identify the physical location of the hard drive that you want to replace (FIGURE 3-2).

2. Issue the Solaris OS commands required to stop using the hard drive.

Exact commands required depend on the configuration of your hard drives. You might need to unmount file systems or perform RAID commands.

One command that you may use to take the drive offline is cfgadm. For more information see the cfgadm man page.

3. Verify that the blue Drive Ready to Remove LED is illuminated on the front of the hard drive.

4. Push the latch release button (FIGURE 3-2).

Caution - The latch is not an ejector. The latch can be damaged if you bend it too much.

5. Grasp the latch and pull the drive out of the drive slot.

3.2.3 Replacing a Hard Drive or Installing a New Hard Drive

The hard drive is physically addressed to the slot in which it is installed.

Note - If you removed a hard drive, ensure that you install the replacement drive in the same slot.

1. If necessary, remove the hard drive filler panel.

2. Slide the drive into the bay until it is fully seated (FIGURE 3-2.).

3. Close the latch to lock the drive in place.

4. Perform administrative tasks to reconfigure the hard drive.

The procedures that you perform at this point depend on how your data is configured. You might need to partition the drive, create file systems, load data from backups, or have data updated from a RAID configuration.

3.3 Adding PCI ExpressModules

The PCI ExpressModules (PCI EMs) plug into the Sun Blade 6000 chassis. To verify installation and to set up the PCI EMs see:
