Re: Adding Disks
run "ioscan" this will identify everything,
run "ioscan -funCdisk" easier to look at and get the device address, if the device address does not show up, run "insf -e" to create all the devices over again.
run "vgextend /dev/vg?? /dev/dsk/
at this point im not sure what you want to do, assuming you want to extend a lvol
--> run "lvextend -l
or maybe you want to use this disk to mirror a volume group.
run the following:
lvextend -m 1 /dev/vg??/lvol1 /dev/dsk/
(repeat for each lvol in that vg)
at this point your done unless you want to split them off. then:
lvreduce -m 0 /dev/vg??/lvol1 /dev/dsk/
(repeat for each lvol in that vg)
you can leave them or setup to pull that disk out
after lvreduce
vgreduce /dev/vg?? /dev/dsk/
if i didn't cover something you wanted to do, let me know.
good luck!!

Re: Adding Disks
I don't know of a way to hot spare JBOD disks. As far as I know you need some type of disk array to use a hot spare. I use those in AutoRaid, Nike and XP arrays.
