Rescan MSA500 G2 Controller after bootup

[Vincent Leung_4]

Hi,

Does anyone know if it is possible to access
HP MSA500 G2 storage if the storage is powered on after the RedHat of DL380 is booted up?

I have tried the ACU utility or the CLI
command "hpacucli rescan" on RedHat Enterprise 3. The utility or command does not find any MSA500 G2 controller but only the internal
SA642 controller.

Anyone's help is appreciated!

Maybe kudzu will work.

Hi yongye,

I tried kudzu before and it does not recognize the MSA500 G2 either.

Thx!

cdrecorder has a command option to scan SCSI bus.

try : cdrecorder -scanbus

Hi Vincent,

make a "lsmod" to see what modules are loaded and unload the driver for MSA500 G2 with "rmmod" and then load it again with "modprobe".

i hope it works!

Yong:

cdrecord -scanbus does not seem to work.


Johannes:

Removing & reinserting the driver may work
but my boot disk is using the same driver
as that of the MSA500 G2 controller. I can't
afford to bring down the driver.

I think the OS is using HP's cciss driver to
access the internal boot disk running on 5iPlus RAID 1 & to the external MSA500 G2 storage controller via the internal SA642
PCI-X controller card. It must be some trick
to do with the cciss driver. Maybe pass some
command to the cciss driver.

i have found something on the hp website:

http://h18023.www1.hp.com/support/files/server/us/download/21189.html

At this location you could download a new driver with the folowing enhancments:

Support for Smart Array 6i Controller.
Support for MSA 500 G2.
Support for MSA 20.
Support for One Button Disaster Recovery (OBDR).
Conversion function for 32-bit user space apps to run on x86_64 architecture.
Script (/etc/init.d/cciss_hotplug) to rescan SCSI bus.

Hi Johannes,

Unfortunately, the cciss_hotplug script that comes with CCISS driver is for rescanning & detecting hot-plug scsi tape drives but not for rescanning MSA500 G2 controller.
