HP Command View EVA refresh

The HP Command View EVA user interface periodically performs an automatic refresh to ensure that the

user interface accurately reﬂects the state of the array. However, the automatic refresh may i nterfere with

your work when you are completing the ﬁeld s on the iSCSI controller properties window. Speciﬁcally,

while you are entering information, an automatic refresh may occur and reset the ﬁelds, causing you to

lose the data you have entered.

one of the following:

• Enter a portion of the data between page r efreshes, and then click Save to store the information .

Enter the rest of the data and then click Save.

• Change the refresh interval for the entire GUI to a larger value in Agent Options > User Interface.
