Status Description Host Status S-VOL Access T-VOL Access
Duplex
The initial copy
operation is
complete, and
the XP12000
storage system
starts performing
asynchronous
update copy
operations from the
S-VOL to the T-VOL
as needed. The
S-VOL and T-VOL of
a duplex pair may
not be identical.
S-VOL =
PPRIMARY T-VOL
= PSECONDRY
Read/write
enabled
Read/write-
disabled.
Read/write access
enabled for
HRX volumes.
Avoid read/write
operations.
SP-Pend
The status becomes
SP-Pend when the
Steady Split mode
is selected for the
split operation.
All S-VOL updates
prior to the split
command are
being copied to
the T-VOL. When
these updates are
complete, the split
T-VOL is identical
to the state of the
S-VOL when the
split started.
S-VOL = PPRI-PNDG
T-VOL = PSEC-
PNDG
Read/write

V-Split
The status becomes
V-Split when the
Quick Split mode
is selected for the
split operation.
Only the S-VOL
differential data
is being copied
to the T-VOL in
background. The
V-Split pairs cannot
be deleted.
S-VOL = PPRI-SUSP
T-VOL = SIMPLEX
Read/write
enabled
Read/write-
enabled, can be
varied online.
Split
The XP12000
storage system stops
performing update
copy operations
for split pairs, and
starts accepting
write I/Os for
split T-VOLs. The
XP12000 storage
system keeps track
of all updates to
the split S-VOL and
T-VOL, so the pair
can be resynched
accurately and
quickly.
S-VOL = PPRI-SUSP
T-VOL = SIMPLEX
Read/write
enabled
Read/write-
enabled, can be
varied online.
