AT-14 and AT-42 Storage Subsystem

Hot Spare Disk
A hot-spare disk is a physical disk that is configured for automatic use in the event that another
physical disk fails. Should this happen, the system automatically switches to the hot-spare disk
and rebuilds on it the data that was located in the failed disk. The hot-spare disk must have at
least as much capacity as the other disks in the System Drive.
If it is necessary to remove and replace disks, it is possible to perform hot swap operations. In
other words, an offline or failed disk can be removed and a new disk inserted while the power is
still on and the system is still operating.
Background Consistency Checking
The AT-14 and AT-42 storage subsystems perform periodic consistency checks of all disks. This
detects the presence of bad blocks, thus reducing the probability of a double failure, which
could result in loss of data.
Managing the Storage Enclosures
AT-14 and AT-42 storage enclosures are managed using a Web management utility embedded in
the storage subsystem.
On a properly configured Titan SiliconServer, this utility is accessible from the System Monitor
page. In addition, the Titan SiliconServer tracks alerts issued by the storage subsystem through
SNMP. To add an storage enclosure to the System Monitor, see
Configuring Devices on the
System Monitor.
