Hi Folks,

Wondered if anyone had any experience with multipath-tools and the IBM XIV
storage (2810 range, possibly others)?

They look like this:

Host: scsi8 Channel: 00 Id: 01 Lun: 01
  Vendor: IBM      Model: 2810XIV          Rev: 10.1
  Type:   Direct-Access                    ANSI SCSI revision: 05

There's an IBM document that describes the configuration of these arrays under
Linux here:

http://publib.boulder.ibm.com/infocenter/ibmxiv/r2/topic/com.ibm.help.xiv.doc/docs/hsag_older_than_1_1/Host_System_Attachment_Guide_for_Linux.pdf

Which provides a multipath.conf that appears to work fine but I was wondering if
anyone has experience of using these arrays with multipath-tools - in particular
I'd like to know what the "host_connect" packages contain and whether you can
avoid installing them with a few manual steps.

Regards,
Bryn.
