The IOMs will reset in a staggered manner. This process can take up to 5 minutes to activate.
Step 7 : Ensure multi-pathing can see all of the expected drives.
a. Execute the following command to verify that there are two paths to each drive:
multipath -ll | findstr -i "active ready running" -c
Step 8 : Ensure Windows MPIO can see all paths to the drives after activating IOM A.
a. Execute the following command:
C:\mpclaim.exe –v C:\Users\Administrator\Desktop\mpclaim_output.txt
b. Verify there are two paths to each drive by issuing the following command:
C:\more C:\Users\Administrator\Desktop\mpclaim_output.txt
c. Verify that the output from the mpclaim_output.txt output appears similar to the following
example.

Note: It could take the OS several minutes to rebuild all the paths to the
drives depending on the workload on the drives and how busy the host is.
Multipathing may have to be verified several times to ensure that all paths are
in an optimal state following the reset of IOM A.
