Adding/scanning scsi bus devices on a running Solaris/Linux system.

With hot swapable devices becoming more of the norm, you need a few handy commands to kick the OS in to doing this.

Solaris: drvconfig - will go out an rescan for new hardware just like at boot time. you will need to follow this with the idisk or tape command to build the /dev entries. Another handy view of Solaris devices, processor, and memory too is: /usr/platform/sun4u/sbin/prtdiag ( the sun4u part is platform dependent)


This scanning idea is old, in computer terms, VMS did it back in 1983 when VAXclusters came out!
