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.

ISCI(4) BSD Kernel Interfaces Manual ISCI(4)NAME
isci -- Intel C600 Serial Attached SCSI driver
SYNOPSIS
To compile this driver into your kernel, place the following lines in your kernel configuration file:
device scbus
device isci
Or, to load the driver as a module at boot, place the following line in loader.conf(5):
isci_load="YES"
HARDWARE
The isci driver provides support for Intel C600 SAS controllers.
CONFIGURATION
To force legacy interrupts for all isci driver instances, set the following tunable value in loader.conf(5):
hw.isci.force_legacy_interrupts=1
DEBUGGING
To enable debugging prints from the isci driver, set the
hw.isci.debug_level
variable to a value between 1 and 4 in loader.conf(5).
The hardware layer in the isci driver has extensive logging capabilities which are disabled by default for performance reasons. These can be
enabled by adding
options ISCI_LOGGING
to the kernel configuration file.

The isci driver first appeared in FreeBSD 8.3 and 9.1.

We currently have a Solaris box connected to a Clariion storage system that is utilising DMP for path failover. I would prefer to use EMC's Powerpath and was wondering if the two can coexist?
Basically, I am struggling to find any documentation on the subject and was wonder if anyone can give me... (2 Replies)
First time writer....take it easy on me.
I had a situation where I lost all paths to EMC disk. There was a failure on the EMC frame. After that was repaired, my server had a difficult time reclaiming all disks and veritas had marked the disks as failed. Veritas was confused. What are some of... (3 Replies)
Hello everyone!
Could anybody help me how to configure a set of disk? From our existing EMC storage, we still have spaces for a new set of disk. I know how to replace a deffective disk but never had experience in setting/replacing a new pair of disk (M1 and M2). My objective here is to increase... (1 Reply)
This may sound like an absolute rookie question, and it is.
I have been working on Migrating our HP and Solaris servers to the new EMC SAN and know the routines backwards.
Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.
Can someone... (1 Reply)
Hi Everyone..

Hello, we have a wierd and urgent problem, with a few of our p595 LPARs running AIX 5.3. The LPARs ran AIX 5.3 TL 7 and booted off EMC SAN disks, using EMC Powerpath. Every boot we run "pprootdev on" and "pprootdev fix". We can issue "bosboot -a" and we can reboot the machines.
Now, on two... (2 Replies)
Hi ,
I have a redhat 5.3 server which has 2 vg.. one is rootvg in local harddisk and another one is applicationvg in SAN.. When I reboot the server , EMC powerpath driver is not starting up automatically. Hence applicationvg is not mounting properly. Therefore I need to unmount it manually and... (4 Replies)
Hi all,
I hope I'm putting my first post at this site into the right forum. I need help finding the EMC disk driver for AIX version 5.3. I have some new EMC disk presented to a backup server of mine, and right now the EMC hdisks show up looking like this in an lsdev:

Hi,
I was trying to uninstall the native MPIO driver on the AIX 6.1 machine we have in our lab and ran into a whole bunch dependent filesets initially. I deleted the disks, fcsX, fscsiX, fcnetX and tried again, but ran into the same error.
Subsequently, I figured out that the OS disks in... (4 Replies)
Hi All..
On to a new implementation with AIX 7.1 san boot from EMC disks (Using NPIV). Anyone played with this recently?
Wondering if we need PowerPath on the AIX clients or has native MPIO matured to replace it. Thoughts?
Thanks

I have few new EMC disks assigned from Stroage. I can pvcreate small disks (8.7GB), but bigger disks (71GB) are giving problem. -f also doesn't help.

Hello All,
Our servers having emc clarion for the data disks. Is that possible to see those san disks raid level from AIX ?

Some storage/disks have been added to an existing AIX 6.1 server. The admin sent me the list of hdisk#'s for the new disks, but I need the corresponding rhdisk# for the same hdisk. (I know from past experience that the rhdisk that maps to an hdisk is not always the same number. For instance,... (5 Replies)
