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. |
