DESCRIPTION

svstat displays the contents of various status, error and statistics data structures for the sv SCSI VMEbus host adaptor. 

The default value for the system argument is /vmunix; for core, the default is /dev/kmem. 

OPTIONS

−z Clear counters.  The values are displayed prior to being cleared. 

−l Download specified firmware_file to the controller, reprogram the controller’s FLASH ROMs, and restart the controller.  If a raw_disk_device is not specified, a disk must be present on the controller that can be opened as /dev/rsdn0c. If a raw_disk_device is specified then it is used instead.  If the firmware download process is interrupted by a power failure, contents of the FLASH will be corrupt and the board will not function. 

−n Display (clear) the state of host adaptor sv n. The default interface is sv0. 

DISPLAY
