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. The
XP1024/XP128/XP12000/XP10000/SVS
200 rejects writes for SP-Pend T-VOLs.
S-VOL = PPRI-PNDG
T-VOL = PSEC-PNDG Read/write. Read/write
disabled.
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
XP1024/XP128/XP12000/XP10000/SVS
200 accepts writes for V-Split T-VOLs. The
V-Split pairs cannot be deleted.
S-VOL = PPRI-SUSP
T-VOL = SIMPLEX Read/write. Read/write,
can be varied
online.
Split The
XP1024/XP128/XP12000/XP10000/SVS
200 stops performing update copy
operations for split pairs and starts accepting
write I/Os for split T-VOLs. The
XP1024/XP128/XP12000/XP10000/SVS
200 keeps track of all updates to the split
S-VOL and T-VOL so the pair can be resynced
accurately and quickly.
S-VOL = PPRI-SUSP
T-VOL = SIMPLEX Read/write. Read/write,
can be varied
online.
Resync The
XP1024/XP128/XP12000/XP10000/SVS
200 does not accept write I/Os for resync
T-VOLs. When a split pair is resynchronized
in normal mode, only the S-VOL differential
data is copied to the T-VOL. When a
suspended pair is resynchronized, the entire
S-VOL is copied to the T-VOL. No update
copy operations are performed during resync
operation.
S-VOL = PPRI-PNDG
T-VOL = PSEC-PNDG Read/write. Read/write
disabled.
Resync-R The
XP1024/XP128/XP12000/XP10000/SVS
200 does not accept write I/Os for resync-r
T-VOLs or S-VOLs. When a split pair is
reverse resynchronized, the
XP1024/XP128/XP12000/XP10000/SVS
200 copies only the T-VOL differential data to
the S-VOL. The reverse resync cannot be
performed on suspended pairs. No update
copy operations are performed during
reverse resync or quick restore.
S-VOL = PPRI-PNDG
T-VOL = PSEC-PNDG Read/write
disabled.
Read/write
disabled.
Suspend The
XP1024/XP128/XP12000/XP10000/SVS
200 does not perform update copy
operations to a suspended T-VOL. The
XP1024/XP128/XP12000/XP10000/SVS
200 marks the entire S-VOL track map as
differential data so the entire S-VOL is copied
to the T-VOL when the pair is resumed. Use
resync command to resume a suspended
pair. Reverse resync and quick restore cannot
be used to resume suspended pairs.
S-VOL = PPRI-SUSP
T-VOL = PSEC-SUSP Read/write. Read/write
disabled.
