S2D ReadyNode - How to replace a failed disk

Replacing the faulty disk

In case the serial number of the target disk is “S400625X”:

1. Run the following command to confirm that the applicable disk is retired from the storage pool.
   If it is not retired, proceed with steps in the "Replacing a not retired disk" section.

   PS C:\> Get-PhysicalDisk -SerialNumber S400625X

   

2. Run the following command to detach the applicable disk from the storage pool.

   PS C:\> $disk = Get-PhysicalDisk -SerialNumber S400625X
   
   	PS C:\> Get-StoragePool -FriendlyName s2d* | Remove-PhysicalDisk -PhysicalDisks ($disk)

   

3. Run the following command to confirm that the detach job is completed.

   PS C:\> Get-StorageJob

   

4. Replace the disk.

5. Wait for a while and run the command in step 3 to confirm that replaced disk is added to the storage pool.
   

6. If necessary, follow the Matrix below to update the firmware of the replaced disk.

Replacing a not retired disk

This step is for the disk that is not retired due to predictive failure so on. If you detach it from the storage pool for replacement, change the status to Retired manually.

NOTE: The following command is an example. Specify the SerialNumber and proceed.

In case the serial number of the target disk is “S400625X”:

1. Run the following command to confirm the target disk.

   PS C:\> Get-PhysicalDisk -SerialNumber S400625X

   

2. Run the following command to change the target disk to Retired.

   PS C:\ > Get-PhysicalDisk -SerialNumber S400625X | Set-PhysicalDisk -Usage Retired

3. Run the following command to confirm that the target disk becomes Retired.

   PS C:\Windows\system32> Get-PhysicalDisk -SerialNumber KZJRPYWG

   

4. Proceed the steps 2-6 in the "Replacing the faulty disk" section.

Additional Information (For identifying the disk location manually)

For Server Manager:

1. Select File service and storage service->Volume->Storage pool.

2. Right-click the target disk that the usage status is in such as cancel from the physical disk field and select Switch drive light.

3. Check the status indicator of disks on the front of a server and identify the location where the indicator is blinking.

4. After identifying, select Switch drive light again to stop blinking.

For PowerShell:

1. Launch the PowerShell with administrator privileges.

2. Run the following command to confirm the disk in which the OperationalStatus is not OK or the HealthStatus is not Healthy.

   Get-PhysicalDisk | Where-Object {$_.OperationalStatus -ne "OK" -or $_.HealthStatus -ne "Healthy"} | ft FriendlyName,SerialNumber,OperationalStatus,HealthStatus,AdapterSerialNumber

3. Run the following command to identify the host that the applicable disk belongs to.

   NOTE: For NVME, use the AdapterSerialNumber instead of the SerialNumber.
   NOTE: Enter the iDRAC IP of the node that configures S2D to the $ips.
   NOTE: Enter the value of the disk that is confirmed in step 2 to the $SerialNumber.
   NOTE: When running $cred, since the following pop-up is displayed, enter the login information of the iDRAC Web console.
   

   $CimOptions = New-CimSessionOption -SkipCACheck -SkipCNCheck -SkipRevocationCheck -Encoding Utf8 -UseSsl
   
   	$cred=(Get-Credential)
   
   	$ips=@('xx.xx.xx.xx','xx.xx.xx.xx','xx.xx.xx.xx','xx.xx.xx.xx')
   
   	$serialNumber = "xxxxxxxxxxxx"
   
   	foreach ($ip in $ips) {
   
   	$Session = New-CimSession -Authentication Basic -Credential $cred -ComputerName $ip -Port 443 -SessionOption $CimOptions
   
   	Get-CimInstance -Cimsession $Session -ClassName DCIM_PhysicalDiskView -Namespace 'root/dcim' |? {$_.serialNumber -eq $serialNumber} | ft PSComputerName, serialnumber,slot, DeviceDescription
   
   	}

   

   Example output of disk serial number S400625X:
   

4. If the failed disk could not be identified, blink all the healthy disks to identify the failed disk.

   • For Power Shell:

     Get-PhysicalDisk | Where-Object -Property HealthStatus -eq Healthy | Enable-PhysicalDiskIdentification

     After identifying, stop blinking.

     Get-PhysicalDisk | Where-Object -Property HealthStatus -eq Healthy | Disable-PhysicalDiskIdentification

   • For iDRAC7/8: Tick all except the failed disk and blink and unblinking.
     

   • For iDRAC9: Tick all except the failed disk and blink and unblinking.
