Resynchronizing Rdr Disks - NEC Express5800/320Ma Administrator's Manual

1. Make sure no disk occupies the slot that is the partner slot to the disk whose RDR
configuration you are removing.
2. If your disk was a dynamic disk, use your disk-management tool to convert the disk
to basic, deleting all data on the disk.
If your disk was a basic disk, use your disk-management tool to delete all volumes
and partitions.
3. In ftSMC, select and right-click the disk, and click Remove Physical Disk From
RDR Virtual Disk.

Resynchronizing RDR Disks

The system automatically resynchronizes disks that are reinserted into the system and
when I/O elements are returned to service. You can also issue a command to
resynchronize a disk with its partner from the ftSMC.
When RDR disks are resynchronizing, the Logical to Physical Mapping details pane
shows the disk that is resynchronizing as SYNCING, and shows the partner disk as
SIMPLEX.
To resynchronize RDR data disks
1. In ftSMC, under the Logical Disk Information icon, right-click the target RDR virtual
disk; that is, the disk that might not be synchronized with its mirror disk.

To delete the RDR configuration from a stored-data disk
but retains its data, see
on a Physical Disk" on page

You must complete the final step. Otherwise, if the former
RDR virtual disk partner of the newly erased disk is
inserted into the partner slot of the erased (but not
deleted) disk, the newly inserted disk is mirrored to the
empty disk, deleting the data on the newly inserted disk.
N O T E
If you insert a blank disk into the companion slot of an
RDR virtual disk, the blank disk is automatically
configured and synchronized to the existing RDR disk.
