Performing CCI Operations
Hitachi AMS 2000 Family Command Control Interface (CCI) Reference Guide
UnBMP: Shows the inconsistent percentage of BITMAP for both P-VOL and S-
VOL.
When the paircreate or pairresync command is executed, the pair undergoes the
full copy or differential copy in the COPY status, undergoes the cyclic copy once,
and then placed in the PAIR status. When a new pair is added to a CTG, which
is already placed in the PAIR status, by the paircreate or pairresync command,
the copy operation halts until the time of the existing cyclic copy after the full
copy or differential copy is completed. Further, it is not placed in the PAIR status
until the first cyclic copy is completed after it begins to act in time to the cycle.
Therefore, the pair synchronization rate displayed by Navigator 2 or CCI may be
100% or not changed when the pair status is COPY.
• P-LDEV#:
Shows the LDEV number of the partner volume of the pair.
• M:
- M = W (PSUS only): For P-VOLs, shows suspension with the S-VOL
read/write enabled. For S-VOLs, shows that write I/Os were
accepted at the S-VOL.
- M = N (COPY, PAIR, PSUE, PSUS only): Shows that read access is
disabled. At this time, make sure of the pair, which is displayed by
Navigator 2, status of which is PSUS (PSUS(N)), and no reading/
writing from/to which is allowed.
