NOTE: When you change the ownership of an array, the LUNs assigned
to the array’s partitions become invalid. After changing ownership, you
must assign a new LUN to each array partition.
To change array ownership:
1.
From the System Menu, select
Array Menu
and press <Enter>.
The Select Array screen displays with a list of existing arrays.
2.
Select the array you want and press <Enter>.
The array menu displays.
3.
Select
Switch Array Owner
and press <Enter>.
4.
The system confirms that you want to make the change. Select
Yes
and press <Enter>.
5.
Assign a new LUN to each array partition. See section D.3.5 on
page 245 .
D.2.9 Trusting an Array
You can use the Trust Array function to bring an array back online by
re-synchronizing the time and date stamp and any other metadata on a
bad disk. This makes the disk an active member of the array again. You
might need to do this when:
• One or more disks of an array start up more slowly or were powered
on after the rest of the disks in the array. This causes the date and
time stamps to differ, which the EF2800 interprets as a problem
with the “late” disks. In this case, the array will function normally
after using Trust Array.
• An array is offline because a drive is failing, you have no data
backup, and you want to try to recover the data from the array. In
this case, the Trust Array function may work, but only as long as the
failing drive continues to operate.
Before you can use this function, you must enable it in the Option
Configuration menu.
