pair status Indicates the condition of a copy pair. A pair must have a specific status for specific operations.
When an operation completes, the status of the pair changes to the new status.
parity group See RAID group.
path failover The ability of a host to switch from using the primary path to a logical volume to the secondary
path to the volume when the primary path fails. Path failover ensures continuous host access to
the volume in the event the primary path fails.
See also alternate path and failback.
PAV Parallel Access Volumes
PDEV physical device
PG parity group. See RAID group.
physical device See device.
pool A set of volumes that are reserved for storing Thin Provisioning write data.
pool volume A logical volume that is reserved for storing snapshot data or write data for Thin Provisioning.
(pool-VOL)
port attribute Indicates the type of fibre-channel port: target, RCU target, or initiator.
PP program product; physical partition
primary site The physical location of the storage system that contains the original data to be replicated and
that is connected to one or more storage systems at the remote or secondary site via remote copy
connections. A primary site can also be called a "main site" or "local site".
The term "primary site" is also used for host failover operations. In that case, the primary site is
the host computer where the production applications are running, and the secondary site is where
the backup applications run when the applications at the primary site fail, or where the primary
site itself fails.
primary volume The volume in a copy pair that contains the original data to be replicated. The data in the primary
(P-VOL) volume is duplicated synchronously or asynchronously on the secondary volume.
The following HP products use the term P-VOL: Business Copy, Business Copy Z, Continuous
Access Synchronous, Continuous Access Journal, and Continuous Access Journal Z.
See also secondary volume.
PV physical volume
quick format The quick format feature in Virtual LVI/LUN in which the formatting of the internal volumes is done
in the background. This allows system configuration (such as defining a path or creating a
Continuous Access Synchronous pair) before the formatting is completed. To execute quick
formatting, the volumes must be in blocked status.
R-JNL restore journal
R-SIM remote service information message
R-site remote site (used for Continuous Access Journal)
RAID group A redundant array of inexpensive drives (RAID) that have the same capacity and are treated as
one group for data storage and recovery. A RAID group contains both user data and parity
information, which allows the user data to be accessed in the event that one or more of the drives
within the RAID group are not available. The RAID level of a RAID group determines the number
of data drives and parity drives and how the data is "striped" across the drives. For RAID1, user
data is duplicated within the RAID group, so there is no parity data for RAID1 RAID groups.
A RAID group can also be called an array group or a parity group.
RAID level The type of RAID implementation. RAID levels include RAID0, RAID1, RAID2, RAID3, RAID4,
RAID5 and RAID6.
RC reference code (of a service information message)
RCU See remote control unit (RCU).
RCU target port A fibre-channel port that is configured to receive remote I/Os from an initiator port on another
storage system.
