[dm-devel] NIC and HBA based multipathing

[Scott Moseman]

Ok, if multipath is grabbing the HBA device so I'm unable to mount it,
that's fine, I will go with that.  So I re-enabled the iSCSI initiator
so that the NIC device would become active and I can see if multipath
will grab both of them.  No luck, but I'm ahead of where I was
previously, so here's my status.

In dmesg, both of the devices are being found on boot...

HBA-

scsi1 : qla4xxx
 QLogic iSCSI HBA Driver version: 5.01.00.08
  QLogic ISP4032 @ 0000:14:01.1 hdma+, host#=1, fw=03.00.01.24
  Vendor: EQLOGIC   Model: 100E-00           Rev: 2.3
  Type:   Direct-Access                      ANSI SCSI revision: 05
qla4xxx 0000:14:01.1: scsi(1:0:1:0): Enabled tagged queuing, queue depth 32.
SCSI device sdb: 8417280 512-byte hdwr sectors (4310 MB)
SCSI device sdb: drive cache: write through
 sdb: sdb1
Attached scsi disk sdb at scsi1, channel 0, id 1, lun 0

NIC-

scsi3 : SFNet iSCSI driver
  Vendor: EQLOGIC   Model: 100E-00           Rev: 2.3
  Type:   Direct-Access                      ANSI SCSI revision: 05
SCSI device sdc: 8417280 512-byte hdwr sectors (4310 MB)
SCSI device sdc: drive cache: write through
 sdc: sdc1
Attached scsi disk sdc at scsi3, channel 0, id 0, lun 0

# multipath -l
30690a018f015191a6472441d1500f057
[size=4 GB][features="0"][hwhandler="0"]
\_ round-robin 0 [active]
 \_ 1:0:1:0     sdb 8:16 [active][ready]

I'm attaching the output of "multipath -v4" since it's lengthy.
There's some references to sdc (although [faulty]) that I don't
understand, but maybe it will help troubleshoot?

My multipath.conf is setup in accordance with
http://kbase.redhat.com/faq/FAQ_51_7170.shtm .

Thanks,
Scott
