3.2.2.2 Configuring RS232
Use the smit tty fastpath to create a tty device on the nodes. On the resulting panel, you can add an RS232 tty by selecting a native serial port, or a port on an asynchronous adapter. Make sure that the Enable Login field is set to disable. You do not want a getty process being spawned on this interface.
3.2.2.3 Configuring Target Mode SCSI
To configure a
rmdev
command, before you can enable that feature. Alternatively you can make these changes to the database (ODM) only, and they will be activated at the time of the next reboot.
If you choose not to reboot, instead setting all the child devices to Defined, you have to run cfgmgr, to get the tmscsi device created, as well as all the child devices of the adapter back to the available state.
Note
The target mode device created is a logical new device on the bus. Because it is created by scanning the bus for possible initiator devices, a tmscsix device is created on a node for each SCSI adapter on the same bus that has the target mode flag enabled, therefore representing this adapter’s unique SCSI ID. In that way, the initiator can address packets to exactly one target device.
This procedure has to be done for all the cluster nodes that are going to use a serial network of type tmscsi as defined in your planning sheets.
