What mount options should be used when storing IBM Rational ClearCase VOBs and views on a NetApp Network Attached Storage (NAS)?
In general the mount options described in the NetApp manual should be used:
USING NETWORK APPLIANCE STORAGE SYSTEMS WITH IBM RATIONAL CLEARCASE
An exception would be in certain circumstances where issues occur with the operating system, in ClearCase or the NetApp itself, or where a specific and rare customer configuration is in use. In such case a mount option might be added for working around a problem.
