Paircurchk - HP StorageWorks P9000 Reference Manual

% (Continuous Access Synchronous only) = Copy operation completion, or percent pair
synchronization.

S-VOL
CR: Shows the copy operation rate (identical rate of a pair).
BMP: Shows the identical percentage of BITMAP both P-VOL and S-VOL.
SF: Shows sidefile percentage of each CT group as sidefile 100% on cache of both P-VOL and S-VOL. Following is
an arithmetic expression using the high water mark (HWM) as 100% of a sidefile space:
HWM(%) = HWM(%)/Sidefile space (30 to 70) × 100
JF: Shows the usage rate of the current journal data as 100% of the journal data space.
P-LDEV# = LDEV number of the partner volume of the pair
M
For P-VOL and "PSUS" state:
M="W" shows that S-VOL is suspending with R/W enabled through the pairsplit.
M="-" shows that S-VOL is suspending with Read only through the pairsplit.
For S-VOL and "SSUS" state:
M="W" shows that S-VOL has been altered since entering SSUS state.
M="-" shows that S-VOL has NOT been altered since entering SSUS state.
For "COPY/RCPY/PAIR/PSUE" state:
M="N" shows that its volume are Read-disabled through the paircreate '-m noread'.

paircurchk

The paircurchk command is used to check the currency of the Continuous Access Synchronous
secondary volume(s) by evaluating the data consistency based on pair status and fence level.
The following table specifies the data consistency for each possible state of a Continuous Access
Synchronous volume. A paired volume or group can be specified as the target of the paircurchk
command. The paircurchk command assumes that the target is an S-VOL. If the paircurchk command
is specified for a group, the data consistency of each volume in the group is checked, and all
inconsistent volumes are found in the execution log file and displayed. Paircurchk is also executed
as part of the Continuous Access Synchronous takeover (horctakeover) command.
