Does that look good ? Yes, that does. I confirmed that priority is set by "1", if I removed "default_prio_callout" from multipath.conf. But, it may be better if user can specify null callout explicitly. Because, for example, user may want to specify that default is "pp_balance_units" but no callout is used for specific devices like following. --------------------------------------------------------- defaults { ... default_prio_callout "/sbin/pp_balance_units %d" ... } devices { device { ... prio_callout "" ... } } --------------------------------------------------------- Regards, Ky (Kiyoshi Ueda)
