Managing I/O nodes

Note: Disk slot mapping is not required on a VMware virtual machine.

Replacing an I/O node with a new node and disks

Because you need to prepare a new ECE storage node and disks, which means you need to find a new ESXi server to provide a new VM to run this as ECE storage node.

See Installing IBM Storage Scale Erasure Code Edition on VMware virtual machine to provide a new VM with the same configuration with storage server node in the ECE recovery group.

See Replacing an I/O node with a new node and disks to replace an I/O node with the new provisioned node.

Replacing a broken I/O node with moving disks into a new node

Use the steps to replace a broken I/O node with moving disks into a new node:
  1. Shut down the broken VM to make sure that the VM is not pingable.
  2. Detach the NVMe and HDD disks for IBM Storage Scale ECE from the broken VM and add them into a new provisioned VM.
    See Installing IBM Storage Scale Erasure Code Edition on VMware virtual machine to provision a new VM.
    Note: The NVMe and HDD disks in the new provisioned VM are the ECE disks that are moved to the server. Ensure that the data on the disks is intact.
  3. Replace the broken I/O node with the new provisioned VM. See Replacing broken I/O nodes with moving disks to new nodes for more details.

Adding a new node into an ECE recovery group

See Installing IBM Storage Scale Erasure Code Edition on VMware virtual machine to provision a new VM and then see Adding new nodes to add new I/O nodes into an ECE recovery group.
