Hello,
I have Red Hat 5.7 running on HP hardware box. All file systems (except root) are in LVM. I have to create a new file-system and Storage team allocated 8 luns to this server. I scanned them on OS level with below command
When I checked in inq, I can only see sd device, it means OS is able to see new devices. But dm devices are not created
When I scan devices, I see below errors in /var/adm/messages
I can not see new devices in "multipath -ll". Did anybody faced this kind of issue or anybody can give some pointer ? It is production box, so reboot is not a option with me, unless that is last resort.
-------------------------------------------------------------
Seems like somebody removed few devices improperly and that left some unusable entries in /dev. I had to run multipath -F and that flushes and fixed the issue.

nvd
NVD(4) BSD Kernel Interfaces Manual NVD(4)NAME
nvd -- NVM Express disk driver
SYNOPSIS
To compile this driver into your kernel, place the following lines in your kernel configuration file:
device nvme
device nvd
Or, to load the driver as a module at boot, place the following lines in loader.conf(5):
nvme_load="YES"
nvd_load="YES"
DESCRIPTION
The nvd driver exposes NVM Express (NVMe) namespaces as disks to the kernel disk storage API. It depends on the nvme(4) driver for notifica-
tion of existing NVMe namespaces and submission of NVM I/O commands.
Device nodes from the nvd driver will have the format /dev/nvdX and are GEOM(4) disks which can be partitioned by geom(8). Note that device
nodes from the nvme(4) driver are not GEOM(4) disks and cannot be partitioned.
SEE ALSO GEOM(4), nvme(4), geom(8), nvmecontrol(8), disk(9)HISTORY
The nvd driver first appeared in FreeBSD 9.2.
AUTHORS
The nvd driver was developed by Intel and originally written by Jim Harris <jimharris@FreeBSD.org>, with contributions from Joe Golio at EMC.
