EDSFF Long (E1.L). Drives
Your system likely came with drives installed. The 1029P-nel32r supports 32 hot-swappable
eDsFF long (e1.l) drives.
The section is intended to address the need to prepare the eDsFF long (e1.l) drives to be
hot-plugged in supermicro superstorage 1029P-nel32r system.
Warning:
Hot removing an eDsFF long (e1.l) drive from any deployed systems re-
quires careful planning. If possible, it is generally a good idea to stop the I/O access to
the target EDSFF Long (E1.L) drive and migrate out its data first. Make sure that the tar
-
get EDSFF Long (E1.L) drive is identified correctly. Then, prepare and remove the target
eDsFF long (e1.l) drive with every precaution.
Removing a Drive Using Linux
examples listed here were done under linux rHel 7.4. Command output in this section may
be abbreviated for easier reading. additional notes are added with marking “
”.
as eDsFF long (e1.l) drive events are generally associated with their /dev entries in linux,
this document shows a method to correlate the slot number of an eDsFF long (e1.l) drive
in a server enclosure to its kernel /dev entry, and prepare the target ssD for hot removal.
Removing an EDSFF Long (E1.L) Drive in the Linux Environment
1. Find the target eDsFF long (e1.l) drive
information. To find the information of any
target eDsFF long (e1.l) drive, such as /dev/nvme12n1 in this example, use the
following command:
# udevadm info -n /dev/nvme12n1 -a
