<pre wrap="">Hi Hantzley
You should read PowerPath Release Notes (P/N 300-001-969) or at least it's page 15 ;-)
"EMC pseudeo devices are not supported with LVM. Instead, native SCSI devices must be used..."
I think EMC messed up with device names as seeen in /proc/devices under "Block devices" and
LVM doesn't recognize them. They used to be called emcpower in older versions of PP I think,
now they are "emcp".

Chris

<pre wrap="">Hi,
I have a CX300 Clariion and a x445 IBM (4 processors and 4GB RAM) server
equipped with 2 Emulex FibreChannel cards which are directly connected
to the cx300's controllers.
My software config is as follows:
Redhat ES 3.0 with Kernel 2.4.21-20.ELsmp
PowerPath 4.3.1
LPFC 2.4 driver kit 7.2.4-1
lvm-1.0.3-15
I created 2LUNs on the cx300, and therefore I can see 4 sd devices on
linux (2 on one path and 2 on the other). After installing PowerPath, I
am able to access the LUNs via /dev/emcpowera1 and /dev/emcpowerb1
respectively.
But I cannot use LVM on these devices directly. However LVM works with
/dev/sd* devices. I wish to use it with the PowerPath devices instead,
so as to have dynamic multipathing.
I also tried to install Veritas Volume Manager; no luck, the eval
version was compiled for kernel.2.4.xx-Hugemem - which is not my present
kernel. I have incompatibility problems because PowerPath 4.3.1 requires
at kernel 2.4.21-15 or 2.4.21-20.
Is there someone who had the same type of problem? Any tip on how to
make LVM run with PowerPath devices?
Thank you in advance for your replies.
Rgds,
Hantzley Tauckoor
