option.
RCUThe RCU detected a logical error while selecting the recordset
to be settled.
RCUThe RCU could not settle the recordset due to a hardware
failure, track condition, or logical error.
Interoperability with Other Products and Functions
Some types of volumes used by non-XP Continuous Access and non-XP Continuous Access
Asynchronous functions can also be used as a P-VOL and S-VOL of XP Continuous Access and XP
Continuous Access Asynchronous. Table 14 (page 37) explains whether non-XP Continuous Access
and non-XP Continuous Access Asynchronous volumes are also usable as XP Continuous Access
and XP Continuous Access Asynchronous volumes.
