I should elorbrate a bit.
I am able to add the drive using the RAID cards config tools.
I guess what I'm really asking is there any utility I can use to help me
get the bus target and lun number??
With adding the Disk to the Array.
I have it working in that I add a drive and tell the card to grow the
array and reboot when it is finished.
And the drive now has spare space at the end.
What I would like to do is have some way of getting linux to see the new
space without rebooting.
I know this is probably impossible.
