CCISS controller rescan

[sandro_14]

Hi,
i've two Proliant DL585 and two MSA500. I had Red Hat AS 3 U2 installed. I mirror the MSA500 with MD. If i switch off one MSA500 the MD device is still working. That's fine. But if i switch on the MSA500 again the driver does not recognize the missing controller

# /usr/sbin/hpacucli controller all show

MSA500 G2 at 202TLYPN3T
Smart Array 5i in Slot 0
Smart Array 642 in Slot 1
Smart Array 642 in Slot 2

the command "/usr/sbin/hpacucli controller rescan" doesnt work.

# rpm -q hpacucli-7.20-16
hpacucli-7.20-16

I can just reboot the two server to resolve the problem. That cannot be answer after which i'm looking for.

Any ideas ??

Thx

Sandro

i'm sure if you coudl get the controller module/driver reloaded it would probe for controllers again, ofcourse this is not possible since unloading the module would also mean that you disconnect the other msa and then you have no fs anymore to load the modules from.
unless, you use internal disks in the system which are on another type of controller?

try rmmod and modprobe of the controller module.

Thank for your reply!

But it will not work because the internal controller (Smart Array Controller) uses the same driver

#cat /proc/driver/cciss/cciss0
cciss0: HP Smart Array 5i Controller
