termination
Termination (also known as a terminator block) refers to the
electrical connection at each end of a SCSI bus. The function of a
terminator block is to provide for a proper electrical transmission
of the data across the cable. SCSI buses require that a terminator be
placed on the output SCSI connector on the last SCSI peripheral.
Data errors may occur in a SCSI bus that is not terminated.
topology
A network topology refers to the physical layout of nodes on a
network.
U
unkill
When a storage system is in active-active mode and a surviving
controller removes the reset from the other controller, it releases it
from a forced reset (also known as unkill). The other controller will
reboot and attempt to come online. See also
V
verify
1
A function of the RAID controller that verifies all blocks of a
disk drive can be read, and may perform bad-block
replacement.
2
A function of the RAID controller that ensures the redundant
data is consistent with the original data. For a mirror set, the
system ensures that the data on the two disk drives is consistent.
for an array type that uses parity for the redundancy, it checks
the parity and fixes any parity errors.
volume set
An array type that is a concatenation (combination) of one or more
partitions on one or more disk drives. The partitions in a volme set
do not have to be the same size. See also partition.
