SuperServer 1029P-NR32R User's Manual

3.5 Chassis Components
Ruler Drives
Your system likely came with drives installed. The 1029P-NR32R supports thirty-two (32)
hot-swappable RSSDs (Ruler SSDs).
This section is intended to address the need to prepare PCIe NVMe SSD to be hot-plugged
in Supermicro SuperServer SYS-1029P-NR32R & SYS-1029P-N32R systems.
Warning:
Hot removing an NVMe SSD from any deployed systems requires careful planning. If
possible, it is generally a good idea to stop the IO access to the target NVMe SSD and migrate
out its data first. Make sure that the target NVMe SSD is identified correctly. Then, prepare and
remove the target NVMe SSD with every precaution.
Warning:
Surprise hot removal of an RSSD can result in loss of all data on the drive. The fol-
lowing instructions must be followed for safe removal of RSSDs.
Removing a Drive Using Linux
Examples listed here were done under Linux RHEL 7.4. Command output in this section
maybe abbreviated for easier reading. Additional notes are added with marking “
”.
As NVMe SSD events are generally associated with their /dev entries in Linux, this document
shows a method to correlate the slot number of an NVMe SSD in a server enclosure to its
kernel /dev entry, and prepare the target SSD for hot removal.
Removing an NVMe Ruler SSD in the Linux Environment
1. Find the target NVMe SSD information. To find the information of any target NVMe SSD,
say /dev/nvme12n1, use the following command:
# udevadm info -n /dev/nvme12n1 -a
…
looking at parent device '/devices/pci0000:3a/0000:3a:00.0/0000:3b:00.0/0000:3c:06.0/0000:43:00.0/nvme/
