Replacing Hot-Pluggable and Hot-Swappable CRUs

C H A P T E R 2

This chapter describes how to replace the hot-swappable and hot-pluggable customer replaceable units (CRUs) in the Sun Fire V215 and V245 servers.

The following topics are covered:

Section 2.1, Devices That Are Hot-Pluggable or Hot-Swappable

Section 2.2, Hot-Plugging a Hard Drive

Section 2.3, Hot-Swapping a Fan Tray

Section 2.4, Hot-Swapping a Hard Drive Fan Tray

Section 2.5, Hot-Swapping a Power Supply

2.1 Devices That Are Hot-Pluggable or Hot-Swappable

Hot-pluggable devices are those devices that you can remove and install while the server is running, but you must perform administrative tasks before or after installing the hardware (for example, mounting a hard drive). In the Sun Fire V215 and V245 servers, the following device is hot-pluggable:

Hard drives

Hot-swappable devices are those devices that can be removed and installed while the server is running without affecting the rest of the server’s capabilities. In the Sun Fire V215 and V245 servers the following devices are hot-swappable:

Fan trays

Hard drive fan tray

Power supplies

Note - In Sun Fire V215 and V245 servers, the chassis-mounted hard drives can be hot-swappable (depending on how they are configured).

2.2 Hot-Plugging a Hard Drive

The hard drives in the Sun Fire V215 and V245 servers are hot-pluggable, but this capability depends on how the hard drives are configured. To hot-plug a drive you must take the drive offline (to prevent any applications from accessing it, and to remove the logical software links to it) before you can safely remove it.

The following situations inhibit your ability to hot-plug a drive:

If the hard drive contains the operating system, and the operating system is not mirrored on another drive.

If the hard drive cannot be logically isolated from the online operations of the server.

If your drive falls into one of these conditions, you must shut the server down before you replace the hard drive. See Section 3.2.2, Powering Off the Server - ALOM Command Line or Section 3.2.3, Powering Off the Server - Graceful Shutdown or Section 3.2.4, Powering Off the Server - Emergency Shutdown.

2.2.1 Removing a Hard Drive

Removing a hard drive from the Sun Fire V215 and V245 servers is a three step process. You must first identify the drive you want to remove, unconfigure that drive from the server, and then manually remove the drive from the chassis.

Perform the following process to remove a hard drive:

1. At the Solaris prompt, type the cfgadm -al command to list all drives in the device tree, including drives that are not configured. Type:

# cfgadm -al

This command should identify the Ap_id for the hard drive you want to remove. For example, the output should look like:


Ap_id                          Type         Receptacle   Occupant     Condition
c0                             scsi-bus     connected    configured   unknown
c0::dsk/c0t0d0                 disk         connected    configured   unknown
c0::dsk/c0t1d0                 disk         connected    configured   unknown
usb0/1                         unknown      empty        unconfigured ok
usb0/2                         unknown      empty        unconfigured ok
usb0/3                         unknown      empty        unconfigured ok
usb1/1                         unknown      empty        unconfigured ok
usb1/2                         unknown      empty        unconfigured ok
usb1/3                         unknown      empty        unconfigured ok
usb2/1                         unknown      empty        unconfigured ok
usb2/2                         unknown      empty        unconfigured ok
usb2/3                         unknown      empty        unconfigured ok
usb2/4                         unknown      empty        unconfigured ok
usb2/5                         unknown      empty        unconfigured ok
usb2/6                         unknown      empty        unconfigured ok
usb2/7                         unknown      empty        unconfigured ok
usb2/8                         unknown      empty        unconfigured ok
----------------------------

2. Type the cfgadm -c unconfigure command to unconfigure the disk. For example, type:

# cfgadm -c unconfigure c0::dsk/c0t1d1

where c0:dsk/c0t1d1 is the disk that you are trying to unconfigure.

3. Wait until the blue Service Action Allowed indicator lights (FIGURE 2-1).

This indicator helps you to identify which drive is unconfigured and can be removed.

FIGURE 2-1 Locating the Hard Drive Release Button and Latch

Figure showing the location of the hard disk drives, hard drive release button, and latch.

4. On the drive you plan to remove, push the hard drive release button (FIGURE 2-1).

The latch opens.

Caution - The latch is not an ejector. Do not bend the latch too far to the left. Doing so can damage the latch.

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

2.2.2 Installing a Hard Drive

Installing a hard drive into the Sun Fire V215 and V245 servers is a two-step process. You must first install a hard drive into the drive slot that you want to install the drive in, and then you must configure that drive to the server.

Perform the following process to install a hard drive.

1. If necessary, remove the blank panel from the chassis.

Note - Sun Fire V215 servers might have a single blank panel that covers the hard drive slot. Sun Fire V245 servers might have as many as three blank panels that cover the unoccupied hard drive slots.

2. Align the replacement drive to the drive slot (FIGURE 2-1).

Hard drives are physically addressed according to the slot in which they are installed. If you removed an existing hard drive from a slot in the server, you must install the replacement drive in the same slot as the drive that was removed.

3. Slide the drive into the drive slot until it is fully seated.

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

5. At the Solaris prompt, issue the cfgadm -al command to list all drives in the device tree, including any drives that are not configured. Type:

# cfgadm -al

This command should help you identify the Ap_id for the hard drive you installed. For example, the output should look like:


Ap_id                          Type         Receptacle   Occupant     Condition
c0                             scsi-bus     connected    configured   unknown
c0::dsk/c0t0d0                 disk         connected    configured   unknown
c0::sd1                        disk         connected    unconfigured unknown
usb0/1                         unknown      empty        unconfigured ok
usb0/2                         unknown      empty        unconfigured ok
usb0/3                         unknown      empty        unconfigured ok
usb1/1                         unknown      empty        unconfigured ok
usb1/2                         unknown      empty        unconfigured ok
usb1/3                         unknown      empty        unconfigured ok
usb2/1                         unknown      empty        unconfigured ok
usb2/2                         unknown      empty        unconfigured ok
usb2/3                         unknown      empty        unconfigured ok
usb2/4                         unknown      empty        unconfigured ok
usb2/5                         unknown      empty        unconfigured ok
usb2/6                         unknown      empty        unconfigured ok
usb2/7                         unknown      empty        unconfigured ok
usb2/8                         unknown      empty        unconfigured ok
---------------------------------

6. Issue the cfgadm -c configure command to configure the disk. For example, type:

# cfgadm -c configure c0::sd1

where c0::sd1 is the disk that you are trying to configure.

7. Wait until the blue Service Action Allowed indicator is extinguished on the drive that you installed (FIGURE 2-1).

8. At the Solaris prompt, issue the cfgadm -al command to list all drives in the device tree, including any drives that are not configured. Type:

# cfgadm -al

This command should identify the Ap_id for the hard drive that you installed. The drive you installed should be is configured. For example, the output should look like:


Ap_Id                          Type         Receptacle   Occupant     Condition
c0                             scsi-bus     connected    configured   unknown
c0::dsk/c0t0d0                 disk         connected    configured   unknown
c0::dsk/c0t1d0                 disk         connected    configured   unknown
usb0/1                         unknown      empty        unconfigured ok
usb0/2                         unknown      empty        unconfigured ok
usb0/3                         unknown      empty        unconfigured ok
