131Command Console V2.5 User Guide
failover For HS-Series controllers, the process that takes place when
one controller in a dual-redundant configuration fails and the
other controller takes over. The other controller continues to
direct the subsystem until the failed controller is again
operational or is replaced.
good A device state that indicates that a device is operational and in
use by a virtual disk.
host The primary or controlling computer to which a subsystem is
attached.
host access ID The target ID of the host computer allows exclusive access to a
particular virtual disk. A virtual disk can be set to allow all or
only one host target ID access to it.
host adapter A device connecting a host system to a SCSI bus. Typically, the
host adapter performs the functions of the lowest layers of the
SCSI protocol. This function may be logically and physically
integrated into the host system.
host functionality You can configure your controller's host port targets for
optimum performance and compatibility.
hot disks Hot disks occur if the workload is poorly distributed across
storage devices. A hot disk is a device with multiple hot spots.
On a hot disk, host I/O requests begin to back up because of the
concentrated request load. Hot disks cause subsystem
performance to suffer.
hot spare In a virtual disk, a device configured to automatically replace a
failed device. If a virtual disk member fails, the controller
automatically replaces the member with the spare device, and it
rebuilds the member's data from the remaining devices in the
virtual disk.
hot spots Hot spots occur if the workload is poorly distributed across
storage devices. A hot spot is a file or a group of files located on
the same device that receive a very high concentration of I/O
requests.
hot swap A method of device replacement in which the system remains
operational during device removal and reinstallation. The
device being removed or reinstalled is the only device that is
not operational during the process.
