IEC335E
CHECK STORAGE SUBSYSTEM X'ssid' DUAL COPY STATUS FOR pri/sec DEVICE addr DUPLEX PAIR STATUS: stat PRIMARY CCA: X'xx' SECONDARY CCA: X'xxx'

Explanation

During Nucleus Initialization Processing (NIP), storage subsystem validation detected an inconsistency in determination of the primary or secondary device of a duplexed volume. The primary device of a duplex pair cannot be associated with a secondary device or the secondary device cannot be associated with its primary. If it is a primary device, it is marked offline. If a secondary device is encountered without a primary, the primary device address may have been Gen'd offline and this case may not be a problem. If the primary device is varied on before the problem is resolved, then I/O operations that may occur to the duplexed volume may result in subsequent error conditions from the subsystem.

In the message text:
ssid
The identifier of the subsystem being processed.
pri/sec
Either PRI or SEC depending on whether the addressed device is the primary or the secondary.
addr
The device number of the affected device in the duplex pair.
stat
Status, can be any of the following:
  • AVAILABLE when the duplex pair is available.
  • PENDING when the copy to establish a duplex pair had been in progress.
  • SUSPENDED when the duplex pair had been put into the suspended state by host command or by the subsystem.
xx
The channel connection address (CCA) value of the devices in the duplex pair returned in the Sense Subsystem Status data.

System action

Processing continues.

Operator response

Use the IDCAMS Cache Utility LISTDATA command to obtain a full status report. The system operator should only vary the primary device online after the problem is repaired.
