ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

PROBLEM OVERVIEW: SAS HDD or SSD Drive Replacement

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:

Note - This is a hot service procedure that can be performed by Customers while the server is running.

DAMAGE ALERT: Perform a visual inspection of the replacement part to make sure that there are no damaged components, connectors, bent pins, damaged packages during shipping, etc). If the part is damaged, don't install it into the system, order a new part. Handle with caution and package carefully the return part to avoid any damages during shipping.

Caution - The drive must be taken offline before it is removed. If it cannot be taken offline, the OS must be shut down to prevent running programs from attempting to use it.

Note - The "cfgadm" commands in this document (and in the Service manual) are for individual drives that are not part of RAID volumes. When a drive is part of a RAID volume, you do not need to unconfigure it before swapping it with a new drive. When replacing a failed drive in a hardware RAID volume, follow the SPARC T7 RAID Drive Replacement Strategies.

WHAT ACTIONS ARE REQUIRED?:

Hard Drive Slot Configuration Reference

Address mapping between the Oracle Solaris OS device paths and physical hard drive slots is not fixed. For many storage administration tasks, the mapping of OS device names to physical hard drive slots must be determined before the task can be performed. See the SPARC T7 Series Servers Administration Guide for information on mapping SAS controller ports to physical drive slots.

Caution - Depending on the configuration of the data on a particular drive, the drive might also be removable while the server is online. However, to hot-plug a drive while the server is online you must take the drive offline before you can safely remove it. Taking a drive offline prevents any applications from accessing it, and removes the logical software links to it.

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

- If the drive contains the operating system, and the operating system is not mirrored on another drive.
- If the drive cannot be logically isolated from the online operations of the server.

Note - If either of these conditions apply to the drive being serviced, you must take the server offline (shut down the operating system) before you replace the drive.

Replace the HDD or SSD

1. Locate the drive in the server that you want to remove.

2. Determine if you need to shut down the OS to replace the drive, and perform one of the following actions:

a. If the drive cannot be taken offline without shutting down the OS, follow instructions in Power Off the Server (SP Command) then go to Step 4.
b. If the drive can be taken offline without shutting down the OS, go to Step 3.

3. Take the drive offline:

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

# cfgadm -al

This command lists dynamically reconfigurable hardware resources and shows their operational status. In this case, look for the status of the drive you plan to remove. This information is listed in the Occupant column.

Example:

Ap_id Type Receptacle Occupant Condition
...
c2 scsi-sas connected configured unknown
c2::w5000cca00a76d1f5,0 disk-path connected configured unknown
c3 scsi-sas connected configured unknown
c3::w5000cca00a772bd1,0 disk-path connected configured unknown
c4 scsi-sas connected configured unknown
c4::w5000cca00a59b0a9,0 disk-path connected configured unknown
...

You must unconfigure any drive whose status is listed as configured, as described in Step b.

b. Unconfigure the drive using the cfgadm -c unconfigure command.

Example:

# cfgadm -c unconfigure c2::w5000cca00a76d1f5,0

Note - Replace c2::w5000cca00a76d1f5,0 with the drive name that applies to your situation.

c. Verify that the drives blue Ready-to-Remove LED is lit.

4. Press the drive release button to unlock the drive and pull on the latch to remove the drive.

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

5. Install the replacement drive or a filler tray.

6. Align the replacement drive to the drive slot and slide the drive in until it is seated.

Note - Drives are physically addressed according to the slot in which they are installed. If you are replacing a drive, install the replacement drive in the same slot as the drive that was removed.

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

Verify the drive functionality

1. Determine if you replaced or installed a hard drive in a running server or not.

a. If you replaced or installed a hard drive in a server that is running (if you hot-plugged the hard drive), then no further action is necessary. The Solaris OS will auto-configure your hard drive.
b. If you replaced or installed a hard drive in a powered-down server, then continue with these procedures to configure the hard drive.

2. If the OS is shut down, and the drive you replaced was not the boot device, boot the OS.

Note - Depending on the nature of the replaced drive, you might need to perform administrative tasks to reinstall software before the server can boot. Refer to the Oracle Solaris OS administration documentation for more information.

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

# cfgadm -al

This command helps you identify the drive you installed. Example:

Ap_id Type Receptacle Occupant Condition
...
c2 scsi-sas connected configured unknown
c2::w5000cca00a76d1f5,0 disk-path connected configured unknown
c3 scsi-sas connected configured unknown
c3::sd2 disk-path connected unconfigured unknown
c4 scsi-sas connected configured unknown
c4::w5000cca00a59b0a9,0 disk-path connected configured unknown
...

4. Configure the drive using the cfgadm -c configure command.

Example:

# cfgadm -c configure c2::w5000cca00a76d1f5,0

Note - Replace c2::w5000cca00a76d1f5,0 with the drive name for your configuration.

5. Verify that the blue Ready-to-Remove LED is no longer lit on the drive that you installed.

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

# cfgadm -al

The replacement drive is now listed as configured. Example:

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:

Following the FE service, the customer may need to run Application or Solaris commands, including but not limited to the following:
- Reconfigure disk as previously configured. e.g. Part of raid volume set or mounted file-system or raw partition or other.
- Volume manager (SVM, VxVM) commands or configuration tasks
- Restart software applications per applicable administration guides to resume system operation.
