Hot Swap
About This Chapter
This section describes how to hot-swap a PCIe SSD.
Hot swap includes the following two ways:
l
Orderly hot swap: Users can directly insert a PCIe SSD when the OS is running, but
needs to notify the OS before removing a PCIe SSD.
l
Surprise hot swap: Users can directly insert or remove a PCIe SSD.
The ES3000 V5 NVMe PCIe SSD disk supports orderly hot swap and surprise hot swap on
V5 servers, but does not support surprise hot swap on V3 servers. The ES3000 V5 NVMe
PCIe SSD card does not support orderly or surprise hot swap.
l
For details about operating systems that support orderly hot swap, see
.
l
Swap only one ES3000 V5 SSD at a time. After one ES3000 V5 SSD is removed or
inserted, wait for at least 3 seconds before swapping or inserting another SSD.
l
SSD hot swap may affect services running on the SSD. Before performing a hot swap,
notify system maintenance personnel to ensure service security.
l
If you insert the ES3000 V5 SSD when it is not installed on a drive tray, it may fail to be
detected.
l
After the ES3000 V5 SSD is removed, wait for at least 3 seconds before inserting it again.
If you insert the ES3000 V5 SSD again when it is halfway removed, it may fail to be
detected.
l
Do not pause when inserting the ES3000 V5 SSD, otherwise, it may fail to be detected and
leads to system exceptions. If the SSD cannot be detected or system exceptions occur,
power cycle the server after the SSD is properly installed.
l
If the ES3000 V5 fails to be detected due to improper insertion, remove and insert it again.
