Hello:
My environment like this:
Host
Multipath
Iscsi dev 1. Iscsi dev. 2
(A/ optimized) (A/ optimized) (ALUA)
Server
Target 1 Target 2
（ser 1) (ser 2)
When dev 1 failed, the IO on dev 1 forward to dev2 without any operation,
So I have no chance to do something for the dev 1’s error.
Before I finish the error on dev1, I do not want any IO on dev1 forward to
dev2.
Is there any Mechanism or method can be used?
Best Wishes.--
