- set the Asymmetric Logical Unit Access State (ALUA) mode for STMF
cc [ flag... ] file... -lstmf [ library... ] #include <libstmf.h> int stmfSetAluaState(boolean_t alua_enabled, uint32_t node);
B_TRUE when enabling ALUA mode; B_FALSE when disabling ALUA mode.
Must be the value 0 or 1.
The stmfSetAluaState() function sets the Asymmetric Logical Unit Access State (ALUA) mode for STMF. When alua_enabled is set to B_FALSE, node is ignored; otherwise, node must be set to 0 or 1. The node setting must be different for each node in a paired configuration. This function should be called only after the STMF proxy door service has been initialized (see stmfInitProxyDoor(3STMF)). When the ALUA state is enabled, all STMF logical units will be registered on the peer node as standby logical units. The standby logical units can then be exported to any SCSI initiator using the existing mechanisms in STMF, stmfAddViewEntry(3STMF) or the add-view subcommand of stmfadm(1M). If ALUA mode is already enabled, it is valid to call this interface again with enabled set to B_TRUE. This action would result in a re-initialization of the ALUA mode and can be used during recovery of a failed peer node.
The following values are returned:
Either alua_enabled or node was incorrectly set.
The API call was successful.
