Xen FAQ Devices

From Xen

Can I identify the physical device in DomU as phy:label=fslabel?

For my xen domUs I'm using a mixture of locah physical partitions (with LVM) and iSCSI disks. For local partitions, I don't have any problem, because LVM volumes are always the same. But for iSCSI disks, devices are assigned in the order they are connected, so I can't be sured that device that now is /dev/sdb (for example) will always be /dev/sdb.

So, is there any way to identify the physical device in the domU configuration not as phy:/dev/sdb, but something like phy:label=fslabel? Or is there any other solution to this problem?

I go with phy:/dev/disk/by-path/ip-*-iscsi-iqn.* If you assign iscsi luns directly as domU's fs without additional partitioning, you could probably also use /dev/disk/by-label/* or /dev/disk/by-uuid/*
