The Volume Maximum Block Count is a value that was introduced in Storage Center 5.0.1. This is to explicitly keep unwanted View Volumes from being created by scripts so as to not accidentally overwhelm the memory on your SAN.
There is no way to increase the Volume Maximum Block Count throguh CompCU. This value can be modified through the Storage Center GUI as shown on page 111 of the 5.5 Storage Center System Manager User Guide:
Viewing and Modifying Replays
The Replay tab appears only on volumes for which there are Replays. From the system tree, select a volume . In the Volume Information window, select Replays. The system displays information about any Replays associated with the selected volume.
Default is 100 maximum view volumes and 16TB of configured volume space. This wizard allows you to modify these limits for:
• The number of view volumes that can be created, and
• The configured amount of space for all view volumes that share a Replay history. Can be set to megabytes, gigabytes, terabytes, or petabytes of space. The Unlimited option applies only to Maximum Configured Volume Space limits.
If you do increase this it would be recommended to monitor your memory utilization.
Looks like there is a new snapshot history attribute called VolumeBlockCountMaxSum that can be modified so the EU should be able create this large of a view volume, but sounds like the memory utilization will need to be monitored while this change is in place.
