Replace Server CRUs

WARNING: Whenever you need to lift the system, get others to assist you. To avoid injury, do not attempt to lift the system by yourself.

WARNING: Opening or removing the system cover while the system is powered on may expose you to a risk of electric shock.

Caution: Do not operate the system without the cover for a duration exceeding five minutes. Operating the system without the system cover can result in component damage.

Caution: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Quantum is not covered by your warranty. Read and follow the safety instructions that are shipped with your product.

Note: It is recommended that you always use an antistatic mat and antistatic strap while working on components inside the system.

Caution: To ensure proper operation and cooling, all bays in the system and system fans must be always populated with a component or a blank.

Bezel

If installed, remove the bezel. See Remove and Install the Server Bezel.

Proper server cooling

To maintain proper server cooling, make sure that all empty drive slots have drive blanks installed if the drive will be removed for longer than 5 minutes. See Remove and Install Drive Blanks.

Adjacent drives

When installing a drive, ensure that the adjacent drive or drive blank is fully installed.

If you insert a drive carrier and attempt to lock its handle next to a partially installed carrier, the partially installed carrier's shield spring can be damaged and rendered unusable.

Replacement drive

If you install a replacement hot-swap boot drive when the server is powered on, the drive automatically begins to rebuild.

Use the blank replacement CRU drive supplied by Quantum, which will be the exact type and capacity as the drive it is replacing. Otherwise, make sure that the drive is the exact type and capacity as the drive it is replacing, and is blank or contains data that you do not need. Any data on the replacement drive is lost during drive configuration.

1. Press the release button to open the drive handle.
2. Slide the drive carrier out of the drive slot.

   Note: If you are not immediately replacing the drive, insert a drive blank in the empty drive slot.



3. Remove the drive from the drive carrier:

1. Log in to the CLI of the server node with the replaced boot drive:
To log to the CLI
1. Open an SSH connection to the appropriate server and use the IP address assigned to the node on the Management or LAN Client network.
2. Initiate an ssh session to the system using Terminal or PuTTY:
To ssh into the system
1. Log in to the command line using the following credentials:
   • User name: stornext
   • Password: <stornext user account password>

     Note: "password" is the default password for the stornext user account. If the password has been changed, use the current password. Beginning with StorNext 7.0.2, you must change the default password for the stornext user account. As of StorNext 7.0.2, the first time you log in, you will be prompted to change the password to a different one.

2. Enter sudo rootsh to gain root user access.
3. Enter the password for the stornext user account again.
2. Open the Service Menu as -admin:
   Launch the Service Menu as the admin User

   To launch the Service Menu, enter:

   sh /opt/DXi/scripts/service.sh -admin

   The Service Menu displays.

3. Select More Tools > SW RAID Tools > SW RAID Repair.

4. The failed disk is reported and a prompt appears requesting if you want to proceed with the software RAID disk repair.

   

5. Press y to begin the software RAID disk repair process.

6. The required replacement drive information is displayed and a prompt appears requesting that you confirm the replacement drive is already inserted. If you have the replacement drive ready or already inserted, press y to continue.

   

7. The failed partitions from the failed drive are removed from the RAID mirror and a prompt appears requesting that you confirm the new drive is installed and locked in its slot. Insert the new drive, if the new drive is not already inserted, and press y.

   

8. The RAID partitions are created on the new drive and the SW RAID disks are repaired to include the new partitions on the new drive. The RAID re-synchronization process is initiated and the Service Menu displays the progress of the re-synchronization process.

   Note: Quantum recommends you wait until this process is completed, before you perform other activities on your system.

   

9. Open an additional SSH session and enter the following to monitor the progress of the rebuild activity:

   cat /proc/mdstat

   A recovery percentage complete displays for each partition that is being rebuilt.

10. When the re-synchronization process is complete, the output displays a healthy status for the RAID disks.
