Forcing a disk to rebuild
Forcing a disk to rebuild
With RAID 0 there is no RAID redundancy, so disks do not rebuild. With other RAID
types, such as RAID 1, if media access (record/play) is underway, when you insert a
media disk it automatically begins to rebuild. If there is no media access underway,
to start the rebuild process either begin a media operation or use the following
procedure:
1. In the tree view, identify the faulty disk. If the disk is not currently in the fault
state, the Rebuild option is not available.
2. In the tree view, right-click the faulty disk and select Rebuild .
3. When the message “Succeeded to start rebuild…” appears, click OK .
The Service LED on the K2 Media Client displays a flashing pattern alternating
yellow/green once a second.
Unbind LUN
You can only unbind one LUN at a time. Also make sure the controller is not busy
with other processes, such as rebuilding a disk. If the controller is busy, the unbind
LUN operation fails.
CAUTION: Unbinding destroys all data stored on disk modules.
To unbind a LUN, do the following:
1. In the tree view, right-click the LUN and select Unbind LUN .
2. If the K2 Media Client is online, messages appear “…offline mode now?” and
“…continue?”. Click Yes to put the K2 Media Client in offline mode.
AppCenter channels go offline.
3. When warning messages appear “…destroy all existing media…” and “Are you
sure?”, click OK to continue.
4. The Progress Report opens and displays unbind progress.
