Hi, Recently I am trying to test few luns with multipath , in two of my test server. I worked throughly with PowerPath. I have few questions on multipath: - what is the logic redhat is using to create the WWID and what are the fields involved - I am trying to test with the shared luns (devices) between two nodes. How i will identify the device id in multipath. Though as per Redhat , they are telling WWID is the identifier. But how i will identify the device id in the WWID? It is very much needed specially for shared luns. In PowerPath, generally all the devices are identified by the lun id /device id then , I use the Pseudo name (linux), for configuring the devices. I will assume that WWID is similar as Pseudoid. If not, pl. correct me. - Where can i match the device id in the WWID.. It will be really appreciated , if someone clears all my questions. Thanks in advance. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
