Name
dmmp_path_status_get - Retrieve the path status. Synopsis
"uint32_t" dmmp_path_status_get (struct dmmp_path *" dmmp_p ");
Arguments
Pointer of 'struct dmmp_path'. If this pointer is NULL, your program will be terminated by assert.
Description
The valid path statuses are: * DMMP_PATH_STATUS_UNKNOWN * DMMP_PATH_STATUS_DOWN Path is down and you shouldn't try to send commands to it. * DMMP_PATH_STATUS_UP Path is up and I/O can be sent to it. * DMMP_PATH_STATUS_SHAKY Only emc_clariion checker when path not available for "normal" operations. * DMMP_PATH_STATUS_GHOST Only hp_sw and rdac checkers. Indicates a "passive/standby" path on active/passive HP arrays. These paths will return valid answers to certain SCSI commands (tur, read_capacity, inquiry, start_stop), but will fail I/O commands. The path needs an initialization command to be sent to it in order for I/Os to succeed. * DMMP_PATH_STATUS_PENDING Available for all async checkers when a check IO is in flight. * DMMP_PATH_STATUS_TIMEOUT Only tur checker when command timed out. * DMMP_PATH_STATUS_DELAYED If a path fails after being up for less than delay_watch_checks checks, when it comes back up again, it will not be marked as up until it has been up for delay_wait_checks checks. During this time, it is marked as "delayed".
