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,
