Don't merge yet, we're still testing on all distros... |

I think the use of $ID_PATH is not going to be very consistent across distributions. In some distributions we do not see ID_PATH configured, or the formatting varies. We might want to revert to using something like "/sys/block/%k/device" as you were in an earlier version. Running "udevadm info --query=property --name=/dev/sdc | grep ID_PATH" I see the following results on various endorsed distros: SLES 11: CentOS 6: CentOS 7: Ubuntu 14.04: Ubuntu 16.04: The lack of ID_PATH or any by-path links in CentOS 7 seems to be a bug and related to this issue: https://access.redhat.com/solutions/1565863 |

There was a problem hiding this comment.
The following seems to work more consistently across distros and versions:
KERNEL=="sr*", GOTO="azure_end"
PROGRAM="/bin/sh -c 'readlink /sys/block/%k/device|cut -d: -f4'", ENV{fabric_name}="datadisks/lun-$result", GOTO="azure_names"
|
That will need a bit of work to also work with partitions... I'll be back |

@szarkos check it out. I've changed it so it now works for:

Okay, one more change coming. People want us to prepare for usage of multiple controllers. |
Adds matching rules for all scsi disks other than root/resource disk
Data disks will show up as /dev/disks/azure/datadisks/lun*, matching the LUN's specified on attach/deploy
Also fixed the test-out matching, since vendor and model were completely ignored
