Web Console computer—this does not affect storage system operations.

• Make sure that ESAM requirements and restrictions are met.

• Make sure that the primary and secondary systems are powered on and

fully operational (NVS, cache).

• Check all input values and parameters to make sure that you entered

the correct information in Remote Web Console (for example, secondary

system S/N, path parameters, P-VOL and S-VOL IDs).

• If you are using Performance Monitor, refrain from using it.
