Wait before hardening meta data (SYNCDEFAULT)

How long do you want the mount process to wait until the meta data is hardened? Specify the number of seconds. The default is that the mount process waits for 60 seconds. The maximum value that can be specified for the wait is 65535. Sync interval values are rounded up to the next 30-second value. For example, specifying 31 seconds results in a sync interval of 60 seconds. This sets the SYNCDEFAULT(t) parameter (PARM) on the FILESYSTYPE TYPE (HFS) statement in the BPXPRMxx member.
