You can operate DR-based hot swap or hot expansion in the following cases:
When an insignificant failure (1 bit intermittent error) that does not disrupt ongoing operations occurs in the CPU or memory.
When the CPU or memory must be added or reduced due to business expansion or reduction.
Note
You cannot use DR for an I/O-equipped system board in which the I/O setting is not disabled. To add or reduce the CPU or memory, it is necessary to verify whether the reduced CPU or memory does not affect the operations in advance.
The kernel memory board cannot be replaced, removed or, moved on all the node models.
