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.
