Re: Fw: [dm-devel] Multipath and SAN Fabric failover



Heya,
Just to make sure that I've covered everything I partitioned the disk
as /dev/sdc and then used lvm2 command:
sorry, I've missed that before. /dev/sdc is only _one_ of your paths to a LUN. multipath will take the right 2 of those sd* to create one dm device file. Have a look if there's somethign in /dev/mapper, also check your udev rules, you need this line in there:

KERNEL=="dm-[0-9]*", PROGRAM="/sbin/devmap_name %M %m", NAME="%k", SYMLINK="%c"

most distros have a line like
#KERNEL=="dm-[0-9]*",           NAME=""
in there, you need to comment it out if you add the lien above.


Hope that helped,

best regards

Bernd Zeimetz
