refreshing the driver info with newly created logical drive with hpacucli

Vinay Tyagi — Wed, 15 Feb 2006 16:37:31 GMT

Hi,
I have an hp proliant dl380 system with smartarray 5i controller.
I am trying to create and delete arrays with the hpacucli utility which I am able to do. But my problem is that these newly created arrays are not exported to the cciss driver. Also, even after deleting the logical drive I still am getting the device nodes at /dev/cciss/XXX

Can somebody guide me on how can I refresh the driver data. Please note that I cannot remove the driver because my OS is on one of the logical drives.

Shalom Vinay,

Suggestions:
1) reboot the system
2) boot the system off the smart array cd and set up the new disk carefully. Don't touch anything but the new configuration or you could end up with an unbootable system.

Vinay,

You can try this command
echo "rescan" > /proc/scsi/cciss/0
(from http://www1.jpn.hp.com/products/software/oe/linux/mainstream/bin/support/doc/option/scsi/mptlinux-3.02.56-4.rhel4.i686.rpm.readme.txt)

but I suggest you to read readme for your cciss driver (BTW, do you work with kernel 2.4 or 2.6?)

I echo Steven on this -- be very careful when working with the SA5i array -- I ended up wiping the entire thing and had to rebuild both the ACU box and the array...

Hey Guys,
Thanks for the help...but I dont see /proc/scsi/cciss is there anything wrong here??
My system is as follow...
Two logical drives..3 gb each..on which I have mirrored my OS..
1 logical drive on which I put data...
I am trying to create a new logical drive for data but it doesnt shows up anywhere in the filesystem...untill I reboot the box...
I am using kernel of 2.4 base...
I wish I could use this 4th logical drive without rebooting the box...

Are you sure that, prior to OS start, that the SA5 is configured for RAID?
