Deporting A Physical Disk From An Rdr Virtual Disk - NEC Express5800/320Ma Administrator's Manual

Deporting a Physical Disk from an RDR Virtual Disk

Deporting a physical disk from an RDR virtual disk makes the deported disk a clone of
its RDR virtual disk partner. You use the Deport Physical Disk from RDR Virtual Disk
command to create backup disks and spare, bootable, RDR virtual disks.
Once a disk is deported, it is hidden from the system and is inaccessible from ftSMC.
It does not become accessible again until it is removed from and reinserted into the
system. You can physically remove and then reinsert the disk, or you can issue the
InitiateBringdown and InitiateBringup commands for the disk slot.
If you insert a disk deported from one system into another system, the disk appears in
ftSMC as Active, Configured, Deported.
A deported disk inadvertently left in the system or reinserted into its original slot
remains an intact backup. It is not automatically resynchronized or overwritten by the
primary RDR virtual disk.
You cannot deport:
•
The last physical disk of an RDR virtual disk if it is bootable or contains a paging file
•
An unmirrored boot disk
•
A dynamic disk
•
A resynchronizing disk
The Deport a Physical Disk from an RDR Virtual Disk command should be grayed out
if the physical disk is not in the valid state (for example, if it is a dynamic disk or a
simplex boot disk) for this command to work properly. A valid deport operation should
rarely fail.
If the Deport a Physical Disk from an RDR Virtual Disk operation requires that the
system reboot, a system-restart dialog box appears, giving you the option to restart the
system immediately or later. If the operation succeeds without requiring a reboot, a
message box indicating success appears.
If Deport a Physical Disk from an RDR Virtual Disk fails, a dialog box indicating the
reason for the failure appears. In this case, the RDR virtual disk is not deported and the
system does not reboot.
After a successful Deport a Physical Disk from an RDR Virtual Disk command, no drive
letters or mount points associated with volumes on the deported disk are preserved.
To deport a physical disk from an RDR virtual disk
1. In ftSMC, right-click the target disk.
2. Select Deport Physical Disk from RDR Virtual Disk.
