Deleting The Rdr Configuration On A Physical Disk - NEC Express5800/320Ma Administrator's Manual

•
That survives a failover (the failure of one of two, duplex components)
•
To which the data traffic goes when disk utilities, like chkdsk, are run
You might use Set As Active RDR Plex, for example, when using the chkdsk
command to check the performance of a particular physical disk in an RDR virtual disk.
To do this, issue the Set As Active RDR Plex command for the physical disk you want
to check; this makes it the active disk. Then disable read-load balancing on the RDR
virtual disk, and run chkdsk on the active disk.
In the following procedure, n indicates a component number that appears in ftSMC.
1. In ftSMC, expand I/O Enclosure - 10 (or 11) , Storage Enclosure, Slot - n, and
then right-click on Disk - n.
2. Select Set As Active RDR Plex.
A message reports that the operation was successful.

Deleting the RDR Configuration on a Physical Disk

Deleting the RDR configuration removes a physical disk from the RDR virtual disk. You
delete one physical disk at a time.
After you delete the RDR configuration on a physical disk:
•
The RDR metadata is deleted, but other data remains on the disk.
•
The disk is no longer an RDR disk and is not part of an RDR virtual disk.
•
You can reconfigure the disk as an RDR disk again, using the Add Physical Disk
To RDR Virtual Disk command.
You can delete the RDR configuration only from basic data disks, not from dynamic
disks, boot disks, or data disks with one or more paging files.
To delete the RDR configuration on a physical disk
1. In ftSMC, right-click the target disk.
2. Select Delete RDR Configuration on Physical Disk for disk 0 (or 1 or 2).
3. Optionally, repeat steps 1 and 2 on the disk with which the deleted disk was
mirrored.
When the second of the mirrored disks is removed from the RDR virtual disk, the
RDR virtual disk is removed.
4. If desired, repeat steps 1–3 for each physical disk to be removed.
