Older Multi-Port servers were shipped with Adaptec RAID controller drivers that are not updated during our software/OS upgrade processes.

We have seen some users experience frequent server crashes due to issues with these old drivers.

Most users will see an error message like this after the crash:


CentOS 5.X & 6.X

Check to see which model of the Adaptec RAID controller your MTP machine is using:

sudo /usr/StorMan/arcconf GETCONFIG 1 AL


The latest drivers can be found on the Adaptec downloads page:



The drivers will come in a .rpm file which should transferred to the target MTP machine and then executed from the command line.
