Description:
Shadow copy creation failed because of error reported by ASR Writer. More info: Automated System Recovery failed the shadow copy, because a selected critical volume is located on a cluster shared disk. This is an unsupported configuration. (0x80042405).
Replace the paths with PA binaries (paths to quest_sc_mw.exe, quest_sc_collector.exe, quest_sc_rep.exe, quest_launcher.exe, quest_agentmgr.exe), and any other apps binaries that should be excluded from reading.
Please follow the procedure carefully:
In our lab:
One: with double quotation and with -service at the end of the line for example:
"S:\Program Files\UltraVNC\WinVNC.exe" -service
And the second line should be the path without double quotation and without the âââ€service at the end of the line for example:
S:\Program Files\UltraVNC\WinVNC.exe
