4.2 Orderly Hot Plug
You can insert the ES3000 V3 disks to running servers. For Linux and Windows, notify the
OS by referring to this section before hot removing the ES3000 V3 disk. Currently ESXi does
not support orderly hot removal of the ES3000 V3.
4.2.1 Orderly Hot Plug of a Disk in Linux OS
Operation Scenario
In Linux, perform the operations described in this topic before performing an orderly hot plug
of an ES3000 V3 disk.
Preparations
You have correctly installed the ES3000 V3 disk on the server.
Configuring Linux kernel
In Linux (such as Red Hat7.0), hot plug of the ES3000 V3 NVMe PCIe SSD disk will cause
unmatched maximum payload size, I/O write errors, and other issues. This is because Linux
does not fully support hot plug. To avoid this issue, make changes to the Linux kernel file.
The changes vary with the Linux OS type.
Perform an operation based on the OS type:

Red Hat (7.0, 7.1, 7.2) and CentOS (7.0, 7.1, 7.2) => Go to
