Maximum Initial Copy Activities: Specifies the number volumes that can be copied concurrently
during an initial copy and resynchronization operations operations. 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 .
SIMs that are sent to hosts are also saved in the SVP. To clear all URz SIMs from the SVP, follow
the procedure below.
CAUTION: If you follow the procedure below to clear all URz SIMs, UR SIMs will also be cleared
at the same time. You cannot only delete URz SIMs. The SIMs of the entire storage system will be
cleared.
To clear all SIMs:
1. Ensure that the XP Remote Web Console main window is in Modify mode.
For detailed information about how to do this, see XP Remote Web Console user's guide.
2. Ensure that the Optional Operation window is displayed.
3. Select Clear SIM at the upper right corner of the window.
A message appears and asks if you want to delete SIMs.
4. Select Yes to delete SIMs.
Enabling or Disabling SIM Reporting
The Optional Operation window can be used to enable CUs to report SIMs (service information
messages) to hosts, or prevent CUs from reporting SIMs to hosts. For detailed information about
SIMs, see
Universal Replicator for Mainframe Software Error Codes .
To change whether CUs can report SIMs to hosts:
1. Ensure that the XP Remote Web Console main window is in Modify mode.
For detailed information about how to do this, see XP Remote Web Console user's guide.
