under such a condition, the paircreate command might be rejected. In this case follow these
steps:
◦ Locate a consistency group number that is not used by any pairs on the Pair Operation
window by sorting the CTG column.
◦ Specify that consistency group number explicitly and execute the paircreate command
with the At-Time Split option using RAID Manager on the host server.
Troubleshooting At-Time Split function using RAID Manager:
Use Case: Using an XP Continuous Access Journal S-VOL as an XP Business Copy P-VOL:
If the status of some pairs belonging to a consistency group cannot be changed, the Pairsplit
command of RAID Manager can end abnormally with the error code EX_EWSTOT. This error
indicates that a timeout has occurred. Probable reasons why the pair status cannot be changed
are:
•
The XP Continuous Access Journal pair belongs to a consistency group. The P-VOL and the
S-VOL of this pair have the same contents. The journal volumes for this pair are full.
•
The XP Business Copy license is invalid.
•
Volumes of the XP Business Copy pair are blocked.
•
The XP Business Copy pair is in a status in which the Pairsplit operation is unavailable. See
“Relationship between L1 Pair Status and L1 Pair Operations” (page 72) .
•
The XP Business Copy pair is a part of cascaded pairs. The other pairs in the cascaded pairs
are in a status in which the Pairsplit operation is unavailable. See
“Relationship between L1
Pair Status and L2 Pair Operations” (page 73) and “Relationship between L2 Pair Status and
L1 Pair Operations” (page 73) .
•
A volume in the XP Business Copy pair is used as an XP Continuous Access or an XP Continuous
Access Journal volume. The XP Continuous Access or XP Continuous Access Journal pair is in
a status in which the Pairsplit operation is unavailable. See
“Interoperability with Other Products
and Functions” (page 26) .
Once these issues are resolved, perform the Pairresync operation and then Pairsplit can be executed.
Suspending Pairs
The Pairsplit-E dialog box (see Figure 34 (page 82) ) allows you to suspend the pairs.
