MSA1000 one battery failed and host can't see any luns after presented

We are setting a msa to build a testing environment.

 

The battery of a controller is shown failed and the write cache is disabled. And the "show connections"  indicated the host ports of the two controllers connected to the san switch are Offline.

 

The host (hpux 11.11) "fcmsutil /dev/td0 get remote all" shows the MSA status " DVC_unopened", and ioscan cannot find out any luns.

 

Questions:

1. Is the failed battery the root cause? Can I make it functional with the bad battery, or I must replace it before I can use it?

2. After enable Hard_address, do I need restart the controller or the whole MSA array?

How time flies~~~
