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
