IEF024I

ICKDSF User's Guide and Reference

Explanation
The system detected a direct access storage device
(DASD) initialized with the RESERVED parameter to remain offline during
allocation processing of one of the following:A VARY online command.
An offline device selected for the VARY command either by response
to message IEF238D or by the allocated/offline installation exit.

The device characteristics of such a reserved volume are
modified during initialization such that the system can recognize
the volume as being reserved for future use and, therefore, prevented
from being brought online.  Refer to ICKDSF User's Guide and Reference for
details about the RESERVED parameter and use as a reserve storage
pool volume. Note: This is not related to a hardware RESERVE used
to ensure successful serialization of shared DASD.

In
the message text: devnum
The direct access storage device.

System action
The system leaves the requested device offline.

Operator response
If this message is unexpected, notify the
system programmer. If this message was issued due to a VARY online
command, select another device. If this message was issued due to
a response to message IEF238D, either reply to message IEF238D with
another device from the list displayed by previous messages IEF448I,
IEF877E or IEF878I, or reply 'CANCEL' to cancel the job.

System programmer response
Ensure that the device is initialized
appropriately. If it is intended to be reserved for future use, no
further action is necessary. If it is not intended to be reserved
for future use by remaining offline, re-initialize the volume so that
it can be brought online. Refer to ICKDSF User's Guide and Reference regarding
re-initializing a device so that it no longer remains offline.
