Figure 10 SIz and TCz: Shared S-VOL / M-VOL
Figure 11 (page 30) shows a volume that is functioning as both an SIz S-VOL and a TCz R-VOL.
This configuration allows you to use SIz to provide additional remote copies of TCz R-VOLs.
Figure 11 SIz and TCz: Shared S-VOL / R-VOL
CAUTION: When you share a SIz S-VOL with a TCz R-VOL as shown in Figure 11 (page 30) ,
the write operation to the TCz M-VOL takes time. When the SIz pair is in the V-Split status, the
write operation to the TCz M-VOL may take longer depending on the time needed for the SIz pair
copying process.
When you split SIz pairs, if a volume is shared with TCzA and SIz, consider the following points:
•
Split the SIz pair after you have changed the status of TCzA pair to Suspend.
•
If you split SIz pairs for each CTG, split the pairs after you have changed the status of all
TCzA pairs in the specified CTG to Suspend, and also make the consistency time (C/T) of the
CTG equal to the C/T of each TCzA pair.
You can also prevent the SIz split operation if it does not meet these points. For details, call HP
technical support. See
(page 108) .
