LSI Logic Fusion-MPT™ driver for LSI53C1020 and LSI53C1030 SCSI host bus adapters

BASEDEV=LSIMPT.ADD

Parameter

• /VERBOSE (or /V) enables the display of a banner, version number, and SCSI bus information during startup of the system.
• /!DM[,] disables use of the IBM-supplied DASD manager (OS2DASD.DMD) for the devices listed.
• /!SM[,] disables use of the IBM-supplied SCSI manager (OS2SCSI.DMD) for the devices listed.
• /EXCLUDE[,] disables a host adapter so that the LSIMPT.ADD device driver does not see the adapter.
• /SYNCH_RATE=n[,n] Where: n = 0, 5, 10, 20, 40, 80, or 160. sets the maximum synchronous transfer rate (in Megatransfers per second) to negotiate with a particular device.
• SYNCH_OFFSET=n[,n] Where: n = 0 up to maximum synchronous offset for the adapter. This option sets the maximum synchronous offset to negotiate with a particular device. The allowable values for this setting are 0 to the maximum synchronous offset supported by the specified adapter.
• /TIMEOUT=n[,n] Where: n = timeout value in seconds for device). The default value for the timer is 10 seconds. If you set the value to less than the system has allocated for a particular device, the system ignores your setting. To turn off the timeout mechanism for a particular device, set the timer value to 0 (zero).
• /DISCONNECT=n[,n] Where: n = ON allows disconnects and is the default value for all devices. OFF does not allow disconnects. This option controls the ability of a device to disconnect during an I/O transfer.
• /QTAG=n[,n] Where: n = the number of queue tags allowed for a device, and is between 0 and 255. The value given in the command line is the depth of the queue for queue tags for the indicated device(s). To disable queue tags, set this value to 0 or 1.
• /WIDTH=n[,n] Where: n = 8 or 16. The value given in the command line option determines the maximum size of data transfers.
