Thanks mate. I'll dig into the doc.

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".

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.
