[Linux-HA] Failover iscsi SAN

[Michael Brennen]

Hi all,

This is not strictly related to heartbeat, but it seems a place to 
start, since someone has almost certainly done this.  Please feel 
free to direct me to a more appropriate resource if needed.

I am follow the setup at the page below, with the idea being to make 
a heartbeat/drbd driven SAN system with failover capability.  This 
specifically says to set the lun in the iscsi target to /dev/drbd2.

When I set up the iscsi target lun to /dev/drbd2, as given in the 
above page, the following error is logged:

ietd: Can't create a logical unit 30 1 0 Path=/dev/drbd2,Type=fileio

Is the /dev/drbdN device required, or can the lun share the 
underlying physical device?  google isn't turning up much in the way 
of specific answers that I've found so far.  Thanks...
