Table 7 Examples of RAID Manager XP commands
RAID Manager XP command Operation
paircreate
(see Figure 13 for the relationship between the
command and pair status.)
• Create Flex Copy XP pairs.
• Execute copy processing from the P-VOL to the
S-VOL.
• Specify the copy pace using the
-c <size>
option
parameter. Specify one of the following values:
1 or 2: Slower
3: Medium
4 - 15: Faster
If you specify Slower, the effect on host I/O
decreases because of the copy processing’s slow
pace. If you specify Faster, copy processing
completes in a short time period. If you omit this
option, Medium is set.
pairsplit
(see Figure 13 for the relationship between the
command and pair status.)
• When you do not specify the
-S
or
-E
option
parameters:
The P-VOL’s status changes to PSUS and the S-VOL’s
status changes to SSUS. If you execute the
pairsplit
command on the pair when the P-VOL
and S-VOL statuses are COPY, the status changes
after copy processing completes. If you execute the
pairsplit
command on the pair when the P-VOL
and S-VOL statuses are PAIR, the status changes
immediately.
• When you specify the
-S
option parameter:
Copy processing does not execute, and the Flex
Copy XP pair is canceled. The P-VOL and S-VOL
statuses change to SMPL.
• When you specify the
-E
option parameter:
Copy processing does not execute, and the P-VOL
and S-VOL statuses change to PSUE.
• You can specify the copy pace using the
-C <size>
option parameter. Specify one of the
following values:
1 or 2: Slower
3: Medium
4-15: Faster
If you specify Slower, the effect on host I/O
decreases because of the copy processing’ slow
pace. If you specify Faster, copy processing
completes in a short time period. If you omit this
option, Medium is set.
