The CTL statement (ConTroLler) defines a controller and its channel ports. Up to eight channel ports are possible.
CTL |
ctl-mn, [type], (chn-path-id,ctl-no, [wwpn]) [,(chn-path-id,ctl-no, [wwpn])] [,(chn-path-id,ctl-no, [wwpn])] [,(chn-path-id,ctl-no, [wwpn])] [,(chn-path-id,ctl-no, [wwpn])] [,(chn-path-id,ctl-no, [wwpn])] [,(chn-path-id,ctl-no, [wwpn])] [,(chn-path-id,ctl-no, [wwpn])] [,CUADD=3F] |
ctl-mn
Mnemonic name of the controller.
Value: | two alphanumeric characters (A...Z, 0...9) or four hexadecimal digits 1000 <= ctl-mn <= FFFF |
type
Operating mode of the controller.
Value: | BLM for all controllers (default value). |
chn-path-id
Channel path identifier of the channel to which the controller is connected.
Value: | channel path identifier as specified in the associated CHN statement. For a description of the CHN statement, see "CHN - Define channel". |
ctl-no
Physical controller number.
Value: | Controllers connected to channel type |
wwpn
World-Wide Port Number (target ID) of the controller port if the controller is connected to a channel with the FC-SCSI protocol.
Value: | 16 hexadecimal digits |
CUADD=3F
Mandatory specification only for the controller connected to FCLINK channel 00 for the hardware test, see section "Configuration for the hardware test".
Notes
Concurrent operation of disk and tape devices on the same channel can cause considerable disturbances in disk I/O operations.
Multiple logical controllers must be defined for a controller with more than 256 device ports on channel type
IBF,MODE=FCP. A separate CTL statement with a different CTL mnemonic must be used for each logical controller. See the example on "Creating device addresses".
