„
(P,T#,L#) (TrueCopy) = port, TID, and LUN as described in the configuration definition
file. For further information on fibre-to-SCSI address conversion, see Appendix C.
„
(Port#,TID,LU-M) (ShadowImage) = port number, TID, LUN, and MU number as described
in the configuration definition file
„
Seq# = serial number of the RAID storage system
„
LDEV# = logical device number
„
P/S = volume attribute
„
Status = status of the paired volume
„
Fence (TrueCopy only) = fence level

CR: Shows the copy operation rate (identical rate of a pair).
BMP:
Shows the identical percentage of BITMAP both PVOL and SVOL.
SF: Shows sidefile percentage of each CT group as sidefile 100% on cache of both PVOL and SVOL. Following is
an arithmetic expression using the High Water Mark (HWM) as 100% of a sidefile space:
HWM(%) = High water mark(%)/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’.
