If all paths fail concurrently and I/O is queued and stalled, do the following:
Enter the following command at a terminal console prompt:
dmsetup message mapname 0 fail_if_no_path
Replace
with the correct map name, such as
mapname
3600601607cf30e00184589a37a31d911. This causes all queued I/O to fail and propagates the error to the calling application.
Reactivate queueing by entering the following command at a terminal console prompt:
dmsetup message mapname 0 queue_if_no_path
