C.2.8 Changing Array Ownership
You can change the ownership of any array between the SMs.
You might want to change ownership if you plan to replace or repair one SM. Changing ownership lets
you continue using an array without interruption and makes the array visible on the SM you change it to.
You can no longer see the array on the original SM.
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
The system confirms that you want to make the change.
4 Select Yes and press Enter.
Assign a new LUN to each array partition.

See C.3.5, ”Changing a Partition LUN”, on page 141.
C.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 Galaxy 65 Subsystem 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.
Caution The Trust Array feature can cause unstable operation and data loss if used improperly. This feature is
intended for disaster recovery.
To trust an array:
1
From the System Menu, select
Configuration Menu
and press
Enter
.
The Configuration Menu displays.
