4-26 Endurance FTvirtual Server Administrator’s Guide
Mirrored disk sets ensure maximum availability of data on the Endurance Configuration. If
degraded, mirrored disks in the Endurance Configuration have these characteristics:
• The target disk of a mirror copy cannot fully service FTvirtual Server requests until its
mirror copy completes.
• If the source disk of that mirror set becomes unavailable for any reason before the mirror
copy completes, the FTvirtual Server no longer has access to that mirror set.
If one member of a mirrored disk set has failed, use the Endurance Manager to attempt to enable
that disk. If enabling the disk succeeds, a mirror copy is automatically queued.
Offline/Missing The physical disk has not been found.
This could be because it is physically
disconnected, powered off, not
properly configured, or otherwise not
functional.
For non-mirrored disks:
The physical disk has not been found.
This could be because it is physically
disconnected, powered off, not
properly configured, or otherwise not
functional.
Offline/Pending
Copy Target
The physical disk is not available for
use because it is the target of a
pending mirror copy.
Transitioning/Copy
Target
The physical disk is the target of an
ongoing mirror copy.
Transitioning/
Pending Copy
Target
The physical disk is the target of a
mirror copy that is about to start.
Unknown/Missing The CoServer to which the physical
disk is attached cannot be accessed.
This can be caused by the loss of
communication between the
CoServers when one CoServer is shut
down.
For non-mirrored disks:
The CoServer to which the physical
disk is attached cannot be accessed.
This can be caused by the loss of
communication when one CoServer is
shut down.
