During TrueCopy operations, the primary and secondary system generate a service SIM when P-VOL or S-VOL pair status changes for any reason, including normal status transitions (for example, COPY to PAIR).
- SIMs generated by the primary system include the P-VOL device ID (byte 13).
- SIMs generated by the secondary system include the S-VOL device ID (byte 13).
For further information about SIMs, see the System Administrator Guide.
