Okay, I'm stuck and I hope someone can help me out. I have a FC server
that has 2 FC arrays already setup on it each with 2TB. I just
connected up 2 more arrays each with 7.5TB and now I'm trying to figure
out how (if possible) I can get FC to see the arrays without rebooting
the server. Is this possible? I'd prefer to get it up and running
without the reboot, and as I"m a newbie to FC SANS on linux, I'm at a
loss. Help anyone?
If they are seen as separate SCSI devices, or LUNs you could try this:
to add a SCSI device, do
echo "scsi add-single-device a b c d" > /proc/scsi/scsi
where
a == hostadapter id (first one being 0)
b == SCSI channel on hostadapter (first one being 0)
c == ID
d == LUN (first one being 0)
I make absolutely no guarantee that this won't cause your server to crash and
burn. The risk is for you to weigh against the loss of service caused by re-boot.
Of course there are other things to take into account also. Does your fibre
adaptor see the new devices, or does that need to be cycled in some way?
