Question : Problem: WTF's up with my iSCSI network config ???
|
|
Experts:
I just purchased an EMC AX4-5i dual-SP SAN appliance; two racks, one for SAS drives and the other with SATA drives. I'm just setting up the appliance and I'm stuck, hoping you all can help me figure something out.
If you look at the attached file you'll notice my vanilla setup: 1 server with 3 NICs connected to a pair of GigE switches configured in a meshed network connecting a pair of SP units, each with two iSCSI ports of their own.
The problem I'm having is that on the server i can only ping one of two switches and only two of four iSCSI ports

an anyone give suggestions on how to design a webpage (jsp/java) to create a text area where lines may be inserted, deleted, moved, sorted dynamically on the page?
We also have text that will be treated as a block or set. Some text will be read only within the block and include input text boxes. Other lines will be read/write with no restrictions (single lines).
My team tells me this is not possible...
Can DHTML accomplish this, or is there a java applet we can purchase?
>>>My team tells me this is not possible...
Anything is possible if you have an unlimited budget, no deadline, and all the developers you need. Given the vagueness of the requirements given my firt impression is that doing an editor with this level of functionality with a web page is like build a bridge out of paper; can probably be done, but steel is a better idea.
Anyway here is someting to help you get started and let you say "CAN BE DONE" to your team.

<P>This text editor is a TEXTAREA element and is content editable by default. Only text can be edited in this tool. However, you can draft HTML in TEXTEditor and press the Append to HTMLEditor button to see the result appended to HTMLEditor. The Append to TextEditor button reverses this process by appending the HTMLEditor's HTML as text to TEXTEditor.<BR/><BR/>

<BR/><P>Both editors use the same function to activate or deactivate editing. The function uses the <b>isContentEditable</b> property to test whether editing is active. Accordingly, the <b>contentEditable</b> property is then reversed to reset editing.
