2.7.12 Array roaming
Array roaming will be activated when hard disks are moved from one slot
to another or from one controller to a new controller. This ensures that the
new controller can be working at all times. You can determine the way of
array roaming through the Auto Array Roaming Control (See 2.7.16
Miscellaneous on page 2-55).
When the Auto Array Roaming Control option is enabled, the
configuration of the disks can be identified and restored and
uncompleted tasks are automatically resumed.
Some hard disk configurations may cause conflicts when moved to a
new controller. You are allowed to view group information, including the
virtual disk and hard disk states, from the Array Roaming page.
To import the foreign/conflict disks, click the Import button and specify
the following options.
2.7.13 Array recovery
With the Array Recovery Utility (ARU), you can recover the disk groups,
logical disks, and volumes. To perform recovery, you must fully
understand the partition state of each logical disk.
A partition of a logical disk can be one of the following states: OPTIMAL,
FAULTY, , REBUILD, or UNTRUST. Each state is described as below:
• OPTIMAL: The partition is working and the data is valid.
• FAULTY: The partition is lost (the member disk is removed or faulty)
and it results in a faulty logical disk. The data on the faulty partition
will be still in sync with data on other partitions. The data on the faulty
partition can be used after recovery.
Note
At the top of the page, you can select the group id and the group
type (JBOD disk, disk group, or volume) for the information to be
displayed. Each group type will have different columns on this page.
Target ID Select an ID (which may be a JBOD ID, disk group
ID, or volume ID) to be used after import.
Members Select the foreign/conflict hard disks to be
imported and restored the configurations. Use the
arrow buttons to move the hard disks from the
Available Members list to the Selected Members
list.
Force to import
abnormal
group Check this option to allow the import of
incomplete disk groups. Without this option, only
normal disk groups and volumes can be restored.
