procedures on troubleshooting interface problems, see the Owner's
Manual.

link to manually add it.

Unresponsive status, rectify using one of the following options:
• To remove the array from the management domain, highlight the
array and then click
Remove link .
• To add an array, click New link .
In Linux, click the Manual button and click OK .
4 If the array still shows an Unresponsive status, contact Dell.
