NAME

rdaemon - Redundant Controller Resolution Daemon

SYNOPSIS

rdaemon system-dependent_arg block_ major_number character_major_number

DESCRIPTION

rdaemon is the redundant disk array controller (RDAC) resolution daemon. rdaemon runs continuously from system boot until system shutdown, and has the responsibility for receiving and reacting to RDAC-related events, the most significant of which are I/O path failures. In the event of an error, it is up to the daemon to determine and direct the appropriate course of action, which may include simply calling for an RDAC driver retry on the alternate path, or, in case of a hard path or controller failures, transferring all logical units over to the surviving controller, and resuming operations on the new path.

OPTIONS

system-dependent_arg

Not currently interpreted by the daemon, but must be present.

block_major_number

The block major number of the RDAC driver.

character_major_number

The character major number of the RDAC driver.

EXIT CODES

None - rdaemon runs as a daemon process and never exits.
