Multipath device name doesn't display correctly

Question

I'm playing with iscsi and I'm trying to figure out why the vendor/product names aren't showing up correctly. I've restarted all the appropriate services along with a reboot.

Listed below are the output along with an excerpt of the config file.

Output:

LUN-48 (1IET_00020001) dm-0 IET,VIRTUAL-DISK
size=480M features='0' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=0 status=enabled
| `- 3:0:0:1 sdb 8:16 failed faulty running
`-+- policy='round-robin 0' prio=1 status=active
`- 7:0:0:1 sdd 8:48 active ready  running
LUN-30 (1IET_00010001) dm-1 IET,VIRTUAL-DISK
size=300M features='0' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=1 status=active
| `- 8:0:0:1 sdc 8:32 active ready  running
`-+- policy='round-robin 0' prio=0 status=enabled
`- 5:0:0:1 sde 8:64 failed faulty running

Here's an excerpt from multipath.conf

devices {
    device {
            vendor "VMware"
            product "Virtual Disk"
    }
}

Answer 1

I'm not sure what you expect your multipath.conf file to accomplish, but what you've shown above is effectively a no-op as far as I can tell. The device section matches devices based on the vendor, product, and revision keywords, and then applies specific overrides. You have some match criteria there, but you're not actually providing configuration information.

Take a look at this document, which shows an example devices section that overrides some global configuration options.

Other than that, the vendor and product names look just fine. IET is the vendor reported by the iSCSI Enterprise Target driver, so I assume that's where you're getting your LUNs.

Answer 2

I can not leave comments, so I'll post this as an answer.

There is possibility that virtualization causes strange vendor/product names, which are not recognized properly by the toolchain. I have had issues with serial numbers on VirtualBox that did not reproduce in non-virtualized environment.
