Condition Recommended action
• Heavy workload: If no SIM was generated,
wait 5 or 6 minutes, and then check the pair's
status.
- If status changed correctly, the failed
operation completed after the timeout
message was issued.
- If the pair status did not change as
expected, heavy workload might have
prevented the operation from being
completed. Retry the operation when the
system has a lighter workload.
• A communication error may have occurred
between the Device Manager - Storage
Navigator computer and SVP. See the Hitachi
Command Suite User Guide for information
and instructions.
There is a pinned track on a
TrueCopy volume.
See Pinned track recovery on page 10-18 for
more information.
Monitoring data is not updated
though the Monitoring Switch option
is set to Enable.
Because the time setting of SVP is changed, the
monitoring data might not be updated. Disable
Monitoring Switch, and then enable again. For
more information about Monitoring Switch, see the
Performance Guide for Hitachi Virtual Storage
Platform Gx00 and Fx00 Models.
