How to identify disk controllers on a sunfire V440
We want to use Volume Manager to stripe our disks on our sunfire 440. The Solaris Volume Manager Administration Guide said, "use disks that are each on different controllers to increase the number of simultaneous reads and writes that can be preformed." How can I determine that disks are on different controllers?
Thanks

give probe-scsi-all command at OK prompt. You will get all the SCSI devices connected to the controller. If no device is connected only controller address will be displayed. The controller address are in /devices directory. The /dev/dsk/cXtXdXsX files are mapped with /devices files. In which cX indicates controller id, you can find the controller number and its device address.
I hope this will fulfill your requirements.
thanks

Check the 440 owners manual, the internal disks can be raid'd within the firmware (clever stuff), external disks keep stripes on the same c? if relevant and mirror across c?.If you use the same size d? (in GB) in svm, then raid 0+1 becomes 1+0 just like 3k per lice vxvm! ;-)
