I am working on simulate disk lost using the following Doc 443835.1
It simulate by changing the permission of the device file. I can simulate in 188.8.131.52 GI. however seems after patch to 184.108.40.206 Jan RU. it doesn't have effect anymore. Even no message appear in the alert.log of ASM
The GI is running on AIX 7.1.
And ALTER DISKGROUP data OFFLINE DISK DKNAME; seems need compatibility higher than 11
the diskgroup is now compatibility 10. Is it still possible to manually offline a disk ?
