6.1.7 Taking Down a Disk Drive
Caution This function is only for testing and could result in data loss. It should not be used in normal operation.
The Down Drive function sets the status of a disk drive in a fault-tolerant array to down. This forces the
Galaxy 65 Subsystem to remove it from the array and marks the array as critical. The downed disk drive
is marked as Leftover and you cannot add it back to the array. You also cannot take down any additional
disk drives in the array.
If you have a properly sized dedicated or global spare, this will cause a reconstruct on the affected array.
For more information about reconstructing an array, refer to the X24 Subsystem Getting Started Guide.
To take down a disk drive:
