Consistency Checking on Demand

By specifying the demandconst option of the mount(1M) command, consistency checks can be performed only when you explicitly request them for file systems mounted with this option. After specifying the demandconst option when you mount a file system in a cache, you use the cfsadmin(1M) command with the -s option to request a consistency check. By default, consistency checking is performed file by file as the files are accessed. If no files are accessed, no checks are performed. Use of the demandconst option will avoid the situation where the network is flooded with consistency checks.
