Hi, All.
I test the iscsi RA on the environment RHEL 5.1 iscsi initiator with
heartbeat and CentOS 5.1 iscsi target. But they sometime do odd
behaviour that not to mount file system. Maybe there is little time to
mount file system after finishing iscsi RA and then Filesystem RA can
not see scsi device on iscsi. So, I add the wait option to iscsi RA
after login to iscsi target.
