Hi All, I am facing a weird problem with RHEL. Following is the setup I have: - OS installed on diskless blades - Blades connected to 2 controllers (so basically 2 paths) - Trying for ALUA support - For ALUA support I derived my code from Hannes check for explicit ALUA support. - Path_grouping_policy group_by_prio - Features 1 "queue_if_no_path" - No_path_retry 20 Problem: - When the failover happens, the standby paths are made active by firing STPG. So far so good. - When the failback happens, some how the standby paths are failed (with messages Failing path 8:XX) even before the preferred controller comes up. - If the failure is show once, init_function is called again and thing move fine, but in case this same error happens twice, the path is marked as failure. In these situation as there are no paths, either hangs or mounted as read-only. - This does not happen immediately, it happens in hour or so when I Am trying continuous failover failback with some gap in between 2 operations. Why does the path fail in such scenarios? How can this be prevented? Please suggest. Regards, Pradipmaya. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
