I don't know if this is exactly the right place to ask this question,
but here it goes. I have installed 2 emulex hbas in a red hat as2.1
server. I first saw duplicate paths to each lun. Now I am trying to
get failover paths to work so if one path goes down the other will pick
up. What I am seeing is the path to /dev/sdj is the only one working.
What I have done so far is edited my /etc/raidtab and put this entry in
raiddev /dev/md0
raid-level multipath
nr-raid-disks 2
chunk-size 4
persistent-superblock 1
device /dev/sdb
raid-disk 0
device /dev/sdj
raid-disk 1
1. I then issued mkraid /dev/md0
2. Made filesystem
3. edited fstab and mounted the filesystem but I don't have failover.
Here is my output from /proc/mdstat
md0 : active multipath sdj[0] sdb[1]
14226368 blocks [1/1] [U]
Is what I'm trying to do feasible or am I completely off track here.
If I am on track what have I missed.
Thanks,
Doug
