In this video, we will cover the process of replacing a failed disk drive in a DS60 expansion shelf First, connect to the system via serial connection or serial-over-LAN For a serial connection, set the baud rate to 9600 or 115200 depending on your system model. The rest of the values are the same for all models 8 data bits 1 stop bit parity none flow control none and VT-100 keyboard emulation Run the “alerts show current” command and note the enclosure number and disk number of the failed disk drive Mapping for the drive slots is located in the DS60 disk replacement documentation Identify the shelf with the failed disk. An amber fault LED will be visible. Next, remove the bezel.
Once the bezel is off, you will need to extend the shelf out from the rack Do not extend more than one shelf at a time to prevent tipping Unscrew the attaching screws from the NEMA channel Then, unscrew the shoulder screws until they are completely free from the rack Use the orange shelf latch handles to slowly extend the shelf out of the cabinet The shelf will lock when it reaches maximum extension Please note, the disk drive must be replaced within 10 minutes of extending the shelf otherwise the other drives may power off to avoid overheating.
Attach an ESD wristband to your wrist and the shelf chassis. Remove the two screws from both sides of the enclosure so that the brackets can be rotated backwards to unlock the top cover Rotate the brackets backwards Slide the cover back to access the hard drives. Look for the amber fault LED to locate the failed disk drive If no fault LED is visible, refer to the disk number you noted earlier from the alert. Slide the disk release tab towards the front of the shelf. Then lift the disk's latch and pull it about 1 inch from it's slot and observe it's amber fault LED to observe if it remains on turns off or fades.
This determines how to proceed with removing the disk drive. If the disk's fault LED remain steady, Pull the disk about 2 more inches from it's slot and wait 30 seconds for it to stop spinning before pulling completely out of it's slot If the disk fault LED turns off or fades after being pulled out 1 inch pull it completely out of its slot. Open the new disk’s latch all the way align the disk with the guides and gently lower the disk into the slot. The latch rotates downward when its tab make contact with the shelf. Push on the latch to engage it With the latch engaged, push firmly on the disk to verify it is properly seated.
The disk’s blue activity LED flashes to indicate the disk is spinning up After the new drive is installed, we need to run some commands to finish the process. The commands are located in the DS60 disk replacement documentation Run the “disk rescan” command to have the system scan for the new disk. This command does not return any output Run the “disk show state” command to display the status of all the disks on the system. The new disk should be listed as rebuilding, represented by an “R”. If any disk is listed as absent, failed, or unknown, run the “disk unfail” command specifying the enclosure number and disk number for that disk Repeat the “disk unfail” command for any additional absent, failed, or unknown disks.
Run the “disk show state” command again to verify the status of all disks When finished, slide the cover forward then rotate the brackets towards the original position and replace th two screws on both sides of the enclosure securing the brackets in place. Once the drive has been verified, use the orange shelf latch handles to slowly push the shelf back into the cabinet. Reinstall the shoulder screws into the same positions they were in before extending the shelf.
Then, reinstall the attaching screws in the NEMA channel Align the bezel with the shelf and push it into place on the rack until it latches You have finished the process of replacing a failed disk drive. At this point, you can terminate the serial or serial over LAN connection For more information on the DS60 expansion shelf see the Dell EMC DD and PowerProtect Hardware Features and Specifications Guide.
