Greetings,

In Resource Manager, what does the "Synchronize Cache Invalid Mode" setting do?  Specifically in the 9500V arrays, but it looks like other arrays have this setting as well.

I did find mention in Synchronous TrueCopy manual about what the "Synchronize Cache All Execution Mode" does.  Normally the array will flush cache contents to disk when a host issues "SYNCHRONIZE CACHE" command.  But if Synchronous TrueCopy is installed, the array will ignore those host sync requests unless this mode is enabled.

Thanks and regards,

H.
