Titan SiliconServer
Titan keeps track of the SDs that are selected for access in its internal data structures, and
assigns each SD a persistent System Drive ID.
If a SD goes off-line, it continues to appear in the
System Drives
page.
If a SD is permanently removed from the system, without having first been deleted, it must be
explicitly removed from the
System Drives
table. From the
System Drives
page, click
details
for the SD which needs to be removed. Then, from the
System Drives Detail
page, click
forget
.
To find System Drives which are not listed in
System Drives
table and to refresh the system
drive list, click
Discover System Drives
.
Status
The current status of the System Drive.
❑
Grey: Not Present. The RAID controller has been out of
contact since Titan was last booted (i.e. a Fibre Channel
cable is loose, etc.) or the RAID controller (if in contact)
reports that the SD has been deleted.
❑
Green: OK. The SD is present and operational.
Note: If the SD is “OK”, it can be
performing other tasks (i.e. initializing in
the background, rebuilding disks, etc.) The
event log may provide more information.

initialization and cannot be used.

Offline. The RAID controller was able to
communicate with the SD when it was booted,
but it is currently out of contact.
❑
Failed. The SD is present but it is unsuitable for
use.
Mirror Status
If the System Drive is bound to another using Synchronous Volume
Mirroring (SVM), the status of the mirrored System Drive is also
shown.
Mirrored To
If mirrored using SVM the ID of the partner System Drive is displayed.
