[libvirt-users] Different SAS controller IDs



Dear All,

I have problem with setting up migration on Intel Multi-Flex server. The problem is that SAS controller IDs (and volume ids in /dev/disk/by-path directory) are different between nodes.

For example on node0 i have:
lrwxrwxrwx 1 root root 9 Jun 29 07:20 pci-0000:04:00.0-sas-0x500015500002040a-lun-0 -> ../../sda lrwxrwxrwx 1 root root 10 May 27 09:17 pci-0000:04:00.0-sas-0x500015500002040a-lun-0-part1 -> ../../sda1
.......

On node1 i have:
lrwxrwxrwx 1 root root 9 Jul 12 21:19 /dev/disk/by-path/pci-0000:04:00.0-sas-0x5000155000020409-lun-0 -> ../../sda lrwxrwxrwx 1 root root 10 Jul 12 21:19 /dev/disk/by-path/pci-0000:04:00.0-sas-0x5000155000020409-lun-0-part1 -> ../../sda1
........

Difference is in 0x500015500002040a and 0x5000155000020409
But this is the matter of migration falure because migration script cannot find needed volume.

Is there any chance to fix it somehow?

Best regards,
Anton Nikiforov
