In a setup of a multiple iscsi disks attached to a Linux host (LVM pools setup), I want to be able to take a snapshot of a specific disk, using Softlayer API.
How can I know the id or the LUN name of the iscsi device from the Linux device name.
For example - get "SLXXXXXXXXX-XX" from "/dev/mapper/YYYYYYYYYYYYYYp1".
I tried resolving the Iscsi target Ip, but it's possible that different disks have same target ip, so I have to figure out a different solution
Using these REST requests you can retrieve the ISCSI id, and LUN id of the device and its parent for those BMS and Virtual Guests that have any.

Method: GET
