Hitachi Universal Storage Platform V TrueCopy for IBM z/OS User’s Guide
Other Operations
The System Option window allows you to clear the remote copy SIMs for the
connected USP V, and to change the option settings of the storage system or
CUs.
Clearing SIMs
The Clear SIM button on the System Option window allows you to clear all
remote copy SIMs (service information messages) from the connected storage
system. Remote copy SIMs include all SIMs issued for TrueCopy for z/OS and
TrueCopy operations.
The clear SIM function is intended for use during disaster recovery operations,
while switching operations to the remote (secondary) backup site.
To clear all remote copy SIMs from the connected USP V:
1. Click the System Option tab, and then click the Clear SIM button (see
Figure 4-13).
2. On the Clear SIM confirmation dialog box, click Yes to clear all remote copy
SIMs from the connected storage system, or click No to cancel your request
to clear SIMs.
3. If you clicked Yes, the storage system verifies that the existing SIMs are
being cleared.
Note: When all SIMs have been cleared, the storage system MESSAGE
lamp on the USP V control panel turns off. This may take up to 30 minutes.
If there are any existing SIMs which are not related to remote copy
operations, the MESSAGE lamp will not turn off.
