Figure 76 Storage System Option Settings in the Optional Operation Window
• Activities: The number of volumes that can be copied concurrently during an initial copy operation.
Figure 77 System Option Panel
• Maximum Initial Copy Activities: Specifies the number volumes that can be copied concurrently
during an initial copy operation. A value within the range of 1 to 128 can be specified. The
default setting is 64 volumes.
Maximum Initial Copy Activities can impact the performance of the primary storage system,
depending on the amount of I/O activity and the number of pairs being registered at the same time.
If Maximum Initial Copy Activities is 64 volumes, it allows you to limit the impact of initial copy
activities on storage system performance. For example, if you set the maximum initial copy activities
to 64 volumes and then add 65 pairs at the same time, the primary storage system starts the first
64 pairs and will not start the 65th pair until one of the pairs is synchronized. When you change
the maximum initial copy activities setting, the new setting applies to pairs created after the setting
was changed, not to existing pairs.
• Set: Closes the System Option window and then adds the settings to the Preview list.
• Cancel: Cancels the settings.
Clearing SIMs
SIMs (service information messages) are messages that are sent from XP disk array to hosts.
For example, SIMs are sent when a failure occurs. For detailed information about SIMs, see
“ Universal Replicator for Mainframe Software Error Codes ” on page 206.
SIMs that are sent to hosts are also saved in the SVP. If you want to clear all URz SIMs from the SVP,
