An occurs when a cannot communicate with a storage array.
If a has only one responsive , all management operations that require communication with the unresponsive controller will fail. If both controllers are
unresponsive, you will receive an error message.
Note:
Before you do any recovery procedure, wait a sufficient amount of time before you make a decision that the storage array is
still unresponsive. The storage management station might take up to five minutes to find out when a storage array has become
responsive or unresponsive.
If a storage array is managed by using both the out-of-band method and in-band method using the same host, a network connection
problem on the controllers might prevent direct communication with the storage array over the network. However, you might
still be able to manage the storage array over the in-band connections. The opposite situation can also occur.
If a storage array is managed through more than one , it is possible that the storage array might become unresponsive to communication over the connections given by one host.
However, you might still be able to manage the storage array over the connections provided by another host.
