RAID quorum Number of intact disks required to maintain data integrity in a RAID set.
RAID rebuild rate The rate at which the RAID configuration rebuilds if a disk is replaced.
RAID status Condition of RAID on the storage system:
•
•
•
•
register Register individual storage systems to use add-on applications. Registration
requires sending in the storage system serial numbers to purchase the license
keys, which are then applied to the storage system.
remote copy pair The primary volume and its related remote volume.
remote snapshot An identical copy of a primary snapshot. The remote snapshot is located on the
same cluster as the remote volume.
remote volume The volume that resides in the Remote Copy location where the remote snapshots
are created. The remote volume contains no data. It acts as a pointer to tell the
system where to make the copy of the primary snapshot. The remote volume can
be stored in these ways:

Repair storage Creates a placeholder in the cluster, in the form of a "ghost" storage system, that
system keeps the cluster intact while you remove the storage system to replace a disk
or replace the storage system itself, and return it to the cluster.
replication level In Release 8.5 this changes to data protection level. Prior to release 8.5,
replication level is the term that designated how many copies of data to keep in
the cluster.
replication priority Removed in Release 8.5. Prior to Release 8.5, replication priority allowed you
to designate whether data availability or redundancy is more important in your
configuration. Release 8.5 forward defaults to availability. This default can be
changed using the Cliq Command Line Interface.
restripe Striped data is stored across all disks in the cluster. You might change the
configuration of a volume, for example, change data protection level, add a
storage system, or remove a storage system. Because of your change, the pages
in the volume must be reorganized across the new configuration. The system can
keep track of several configuration changes at once. This means you can change
configurations, even while a volume is in the midst of a different reconfiguration.
RAID 5 - data blocks are distributed across all disks in a RAID set. Redundant
information is stored as parity distributed across the disks.
RAID 50 - mirrored sets of RAID 5 disks.
Normal - RAID is synchronized and running. No action is required.
Rebuild - A new disk has been inserted in a drive bay and RAID is currently
rebuilding. No action is required.
Degraded - RAID is not functioning properly. Either a disk needs to be re-
placed or a replacement disk has been inserted in a drive.
Off - Data cannot be stored on the storage system. The storage system is offline
and flashes red in the network window.
