Multipathing
I have two ML570G4 with MSA 2000 storage.In ML570 I have two Emulex HBA. OS is RHEL 4.6 and kernel version is 2.6.9-42.ELsmp. Emulex driver which I am using is hp-lpfc-8.0.16.40-5. Problem is that I configured 4 logical drives in MSA2000 now problem is that on linux it showing 8 logical drives. question is that is secure path available for RHEL4 or is any other procedure to configure these paths or drives.

Re: Multipathing
multipath is built into the OS. If there are two paths it will be recongized.
RHEL 4.6 and kernel version is 2.6.9-42.ELsmp.
The kernel version you state does not match RHEL 4.6. This inconsistency can cause loss of functionality.

Re: Multipathing
To enable multipathing
# chkconfig multipathd on
# serivice multipathd start
The command
# multipath -l
will show you the paths recognised.
You may need to create the /etc/multipath.conf file as I'm not sure the code in RHEL4.7 understands the MSA2000. The documentation in the HP DM kit v4 shows the values for the file.
