disabling pci parity checking prevents false parity errors that can cause system problems. the syntax is: set pci_parity value the options for value are: enables fast scsi to perform in either standard or fast mode. if the system has at least one fast scsi device, set the default controller speed to fast scsi (1). devices on a controller that connects to both standard and fast scsi devices will perform at the appropriate rate for the device. if the system has no fast scsi devices, set the default controller speed to standard scsi (0). if a fast scsi device is on a controller set to standard, it will perform in standard mode. the syntax is: set pk*0_fast scsi_speed the options for scsi_speed are: sets the controller host bus node id to a value between 0 and 7. each scsi bus in the system requires a controller. buses can theoretically on (default) enables pci parity checking. off disables pci parity checking. 0 the controller is in standard scsi mode. 1 (default) the controller is in fast scsi mode. # $ ) 0 ) $$ ' support up to eight devices; however, the eighth device must always be a controller. each device on the bus, including the controller, must have a unique id, which is a number between 0 and 7. this is the bus node id number. on each bus, the default bus node id for the controller is set to 7. you do not need to change the controller bus node id unless you place two or more controllers on the same bus. to list the controllers on your system, enter the command show device (see page 4-9). scsi devices begin with the letters ?pk? (for example, pka0). the third letter is the adapter id for the controller. when entering the command set pk*0_host_id , replace the asterisk with the adapter id letter. the syntax is: set pk*_host_id scsi_node_id the value for scsi_node_id is the bus node id, a number from 0 to 7. enables or disables scsi terminators. this command applies to systems that use the qlogic isp1040 scsi controller. the qlogic isp1040 scsi controller implements the 16-bit wide scsi bus. the qlogic module has two terminators, one for the low eight bits and one for the high eight bits. the syntax is: set pk*0_soft_term value the options for value are shown in table 4-14. table 4-14 pk*0_soft_term options option description off disables termination of all 16 bits. low (default) enables low eight bits and disables high eight bits. high enables high eight bits and disables low eight bits. on enables all 16 bits. diff places the bus in differential mode. # $ ) 0 ) $$ ' enables or disables login to the srm console firmware on alternate operator console ports. if the environment variable console (see page 4- 19) is set to serial, the primary operator console device is the terminal connected through the com1 port. the command set t_allow_login 1 enables logins through either the com2 port or a graphics monitor. the syntax is: set tt_allow_login value the options for value are: ./.; " ' # ) the help command displays basic information about srm console commands. the syntax is: help [ command . . . ] example 4-13 help command >>> help set name s et function set an option or modify the value of an environment variable. synopsis set |
