REMOVAL/REPLACEMENT INSTRUCTIONS

PROBLEM OVERVIEW: Hard Disk failure

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

1. Prepare for servicing:

To hot-swap a drive, you must first take it offline. This prevents applications from accessing the drive and removes software links to it. A hard disk drive should not be hot-swapped when either of the following
conditions exist:
The hard disk drive contains the sole image of the operating system that is, the operating system is not mirrored on another drive.
The hard disk drive cannot be logically isolated from the servers online operations.

If either condition exists, you must power off the server before replacing the drive.

Locate a Faulty Hard Disk Drive
This procedure describes how to identify a faulty HDD using the fault LEDs on the drive.
View the hard disk drive LEDs to determine the status of the hard drive.
When the amber Service Required LED on the front of a drive is lit, a fault has occurred on that drive. The following table explains how to interpret the hard disk drive status LEDs:

NOTE: The front and rear panel Service Action Required LEDs are also lit when the system detects a hard disk drive fault.

NOTE: The operating system should be configured by the customer such that the disk drive is free for replacement, e.g. the disk may be part of Solaris Volume Manager, Veritas Volume Manager, mounted file-system, raw partitions, etc. If the disk is part of a hardware RAID volume, the customer should verify it is seen and the volume is re-syncing. A data backup may be required to restore data onto a replaced disk. If a data backup is not required, it is still a wise precaution.

Hard Drive Slot Configuration Reference

This topic describes the hard drive slot organization:

https://docs.oracle.com/cd/E19836-01/E20746/z400076e1521490.html#scrolltoc

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 T3 series servers administration guide for information on mapping SAS controller ports to physical drive slots.

WHAT ACTIONS ARE REQUIRED:

NOTE: Please be aware that Disks could be in hardware raid volumes. 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 T3-1 RAID Drive Replacement Strategies at: http://docs.oracle.com/cd/E19836-01/E20746/z40000081535370.html#scrolltoc

Remove a Hard Disk Drive Filler Panel

1. Attach an antistatic wrist strap.
2. On the hard disk drive filler panel you want to remove, complete the following tasks.

Caution: The latch is not an ejector. Do not bend it too far to the right. Doing so can damage the latch.

a. Push the release button to open the latch and unlock the drive filler panel by moving the latch to the right.
b. Grasp the latch and pull the filler panel out of the drive slot.

Caution: When you remove a hard drive filler panel, replace it with another filler panel or an HDD; otherwise, the server might overheat due to improper airflow.

Remove a Hard Disk Drive

This procedure can be performed by customers while the server is running.

1. Determine if the hard drive can be replaced via the hot-swap or cold-swap procedure and perform one of the following actions:

A Cold-Swap is required if: The drive contains the sole image of the OS and and the OS is not mirrored on another drive. Or the drive cannot be logically isolated from the servers online operations. If yes, shutdown the OS, and power off the server.
A Hot-Swap can be done if: The drive can be taken offline without shutting down the OS. If yes, go to Step 2.

2. Take the drive offline:
a. At the 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.

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

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.

3. On the drive you want to remove, complete the following tasks.
a. Push the release button to open the latch.
b. Unlock the drive by moving the latch to the right.
c. Grasp the latch and pull the drive out of the slot.

Caution
The latch is not an ejector. Do not bend it too far to the right. Doing so can damage the latch.
When you remove a hard drive, replace it with a filler panel or another hard drive; otherwise, the server might overheat due to improper airflow.

Installing the Hard Disk Drive

Installing a hard disk drive into a server is a two-step process. You must first install the hard drive into the drive slot, and then configure that drive to the server.

Note: 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. Hard drives are physically addressed according to the slot in which they are installed.

1. Unpack the hard disk drive and place it on an antistatic mat.
2. Verify that the release lever on the hard drive is fully opened.
3. Install the drive by completing the following tasks.

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.

a. Slide the drive into the drive slot until it is fully seated.
b. Close the latch to lock the drive in place.
4. Return the drive to operation by doing one of the following:
If you cold-swapped the drive, restore power to the server.
If you hot-swapped the drive, configure it using the cfgadm -c configure command. The following example shows the drive at c2::w5000cca00a76d1f5,0 being configured.

# cfgadm -c configure c2::w5000cca00a76d1f5,0

Install a Hard Disk Drive Filler Panel

1. Verify that the release lever on the disk drive filler panel is fully opened.
2. Install the drive by completing the following tasks.
a. Slide the drive filler panel into the drive slot until it is fully seated.
b. Close the latch to lock the filler panel in place.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Boot system and monitor boot sequence for errors. Test functionality of system. Restart software applications per applicable administration guides to resume system operation.
