The warning CMMVC6369W received by IBM Spectrum Protect
Snapshot's SvcAdapter module from the SVC confirms that the
reason for the abort of the snapshot
operation is due to the used amount of SVC storage approaching
the licensed virtualized storage capacity for the SVC.
This is a soft warning from the SVC and the SVC can continue
FlashCopy operations until the used storage has exceeded the
licensed capacity.
IBM Spectrum Protect Snapshot should not abort the unmount
operation due CMMVC6369W.

IBM Spectrum Protect Server version Affected: IBM Spectrum
Protect Snapshot versions 8.1 and
IBM Tivoli Storage FlashCopy Manager versions 4.1


Initial Impact: Medium
