Setting up Multipath on iSCSI and OVM 3.2.4 or later

1544183Mar 31 2014 — edited Apr 3 2014

Hi all,

I really wanna try on multipath setup for iSCSI storage.  I'm using OVM 3.2.4.  I ran OVM and OVS as virtualbox images.  I turned on OVM iSCSI and setup some targets.  I would like to know whether my config is right.

1) OVM (Oracle VM Manager):

two virtual network cards: 10.1.1.101 and 192.168.57.101

I created a virtual disks as /dev/sdc and add it to target.conf:

<target iqn.ovm1.myoracle.com:ovm1.target1>

  backing-store /dev/sdc

</target>

2) OVS (Oracle VM Server):

I ran two times discovery:

iscsiadm --mode discoverydb --type sendtargets --portal 192.168.57.101:3260 --discover

iscsiadm --mode discoverydb --type sendtargets --portal 10.1.1.101:3260 --discover

then restart the scsi.  Now, I have discovered two devices: /dev/sdc and /dev/sdd

I checked multipath:

[root@ovs1 ~]# multipath -ll

1IET_00010001 dm-1 IET,VIRTUAL-DISK

size=2.0G features='0' hwhandler='0' wp=rw

|-+- policy='round-robin 0' prio=1 status=active

| `- 3:0:0:1 sdc 8:32 active ready running

`-+- policy='round-robin 0' prio=1 status=enabled

  `- 4:0:0:1 sdd 8:48 active ready running

Just wanna know whether this means the multipath is configured successfully.
